Whatever you say, our lifestyle often determines not only our musical tastes, but also our predisposition to a certain character of sound. For example, constantly listening to tracks through small desktop speakers, on the one hand, you get used to the limitations of their low-frequency capabilities, and on the other, you subconsciously begin to yearn for real bass. Such cognitive dissonance violates internal harmony, but it is not easy to combat it - floor standing or even massive shelf holders are not always appropriate and not everywhere. One of the ways to “harmonize” compact sound is offered by Neat Acoustic, which we’ll talk about this time.
Neat Acoustic is a small but well-known company based in the north of England in the town of Tisdale. The word "Neat" can literally be translated as both "elegant" and "clear", although in this case it is also an abbreviation for "North Eastern Audio Traders". This was the name of the store where the history of the company began.
Russian audiophiles are already familiar with Neat Acoustic speaker systems, and in December last year its founder and chief developer Bob Sergener even came to Moscow. The visit, by the way, was timed to coincide with the beginning of Neat Acoustic’s cooperation with the new Russian distributor Alef Hi-Fi and the presentation of the Naim Uniti line of digital sources, which Bob himself considers the most worthy companions for his speakers.
According to Bob Sergener's idea, IOTA can be used both in monitor mode and for general sound recording of a living space
The figure of the company's founding father is very important in this case, since the Neat Acoustic speakers owe both the general character and the nuances of their sound to this man. The fact is that Bob is a multi-instrumentalist musician with extensive experience in live performances and recording sessions. He has been developing and producing speakers on an industrial scale for a quarter of a century, and all this time the main criterion for their tuning has been musicality and liveliness of sound. Instrumental measurements, of course, are also carried out, but the resulting digital data is not an end in itself for the Neat Acoustic team, but only certain reference points on the path to sound that is correct from the point of view of demanding, trained listeners.
Moving in this difficult direction, Sergener uses quite complex and rare solutions in his acoustics. For example, the isobaric design of the low-frequency section, which allows achieving excellent bass characteristics for speakers of reasonable physical dimensions.
The most compact
In the Neat Acoustic IOTA model range, they are the most compact and simplest speakers in design. They do not have any isobaric chambers inside, and yet they are directly related to all of the above. However, first things first.
They are actually very small!
So, IOTA are very small (front panel 20x13 cm), but unexpectedly weighty (3 kg each) speakers, designed for horizontal placement. The 2.6-liter body is assembled from thick MDF panels and filled with damping material. By design, it is a bass reflex with a rear-facing port. There are two speakers: a 10-centimeter low-frequency/mid-range driver with a polypropylene diffuser and a ferrite magnet, as well as an EMIT ribbon tweeter with a 5-centimeter diaphragm. The tweeter is loaded onto a small horn milled directly into the front panel.
The original Neat Acoustics stands are made entirely of stainless steel and are quite stable
On the back surface there were a pair of good quality gold-plated (golden-colored) terminals and a pair of threaded holes for wall mounting. The volume of the bass reflex is impressive: its pipe with a diameter of 38 mm stretches to almost the entire depth of the body. A modest paper label pasted next to the port informs that these (let me remind you once again - the most budget-friendly in the Neat Acoustic catalogue) speakers are “Manufactured in the UK”. Please note that they were not “designed” or “seen in a dream by the chief engineer,” but “manufactured” without any guile.
Speaker systems Neat Iota Alpha
Usually, acoustics are confidently divided into bookshelf and floor-standing, but the current case is a clear exception. The size of the system matches large monitors, but with high spikes for installation at the zero level. The height of the new systems from the famous British manufacturer is about 50 cm, but I didn’t have to sit on the floor to listen to them.
It takes a certain amount of courage to create things that can change our usual ideas, and especially in such a conservative field as electroacoustics. Of course, there are also unique designer models on the market, but this is a very specific and narrow niche that is not always directly related to sound. For NEAT Acoustics, on the contrary, sound has always been in the first place, and all design decisions were subordinated solely to one goal - to obtain the deepest possible bass and powerful dynamics with the smallest possible body volume. Hence the isobaric load of low-frequency drivers in older models, “floating” front shields and other tricks. By the way, NEAT is an abbreviation for North East Audio Traders, and literally means elegant, neat, neat.
The Iota Alpha model is somewhat simpler than, for example, the recently tested Momentum SX5i, but its design also shows the developers’ love for non-standard solutions. The body, made of 15 mm MDF boards, has a height of 45 cm (excluding tenons) and is divided into two parts. The closed top compartment and angled front panel houses a 4-inch Tymphany Peerless midrange driver with a Nomex composite cone. Next to it is the Monacor ribbon tweeter, the two-inch radiating element of which is capable of reproducing spectral components up to 22 kHz.
The lower part of the body is reserved for the bass section, which, according to the manufacturer, covers the range from 33 to 80 Hz, i.e. in fact, this is a real subwoofer. And no isobarics - the 5.5-inch paper low-frequency driver is directed downwards and works in a bass-reflex design. The port of an impressive cross-section is brought out to the rear. High spikes determine the optimal gap between the diffuser and the floor, but bass reproduction will depend on the nature of the surface. As experience shows, the best covering in such cases is a dense rug with low pile.
The Iota Alpha model is somewhat simpler than, for example, the recently tested Momentum SX5i, but its design also shows the developers’ love for non-standard solutions.
The manufacturer does not say anything about the circuit design and order of the separation filters; it is only known that the circuit parts were carefully selected from the assortment of different companies and connected by surface mounting. These are English ICW Clarity capacitors and Volt coils, as well as German products from Mundorf and Audaphon. There are two input terminals, because chief designer Bob Sergener believes that with well-designed crossovers, there is no point in installing bi-wiring.
The sensitivity of Iota Alpha is more typical for shelf systems than for floor-standing ones - 86 dB/W/m with a nominal impedance of 4 Ohms. This means that you won’t be able to save on an amplifier - these kids need good current and damping in the low-frequency region.
The finishing is extremely neat, the veneer is selected according to texture and pattern. In addition to black oak (pictured), standard options include natural oak, American walnut and matte white finish.
Despite their modest dimensions, these systems require free space. Firstly, the bass reflex is directed back, and with a powerful bass component, the air flow from the port is great. We must pay tribute to the developers - the rustling and “sighs” characteristic of a turbulent flow are not heard, but the distance from the rear wall should still be at least half a meter. The second interesting point is that Iota Alpha, like a short-throw projector, forms a picture at a certain height, slightly pushing it forward. This is thanks to the angular radiation of the MF/HF link with a carefully selected radiation pattern. The closer you sit, the lower the soundstage will be and the less noticeable the depth perspective will be. In our case, the optimal distance turned out to be 3 - 3.5 meters from the front line. And the width of the stereo base can be adjusted by installing the speakers with tweeters inward or to the sides. Which option is best will depend on the size of your room.
High spikes determine the optimal gap between the diffuser and the floor, but bass reproduction will depend on the nature of the surface.
In our system, with a fairly wide arrangement of speakers, the space was filled densely and evenly. I must note that Iota Alpha is not the kind of acoustics that concentrates imaginary images in the center of the stage, but itself seems to disappear. On the contrary, she actively participates in shaping the picture, thanks to which the foreground becomes even wider. This feature will be useful in a home theater - even with a small distance between the front speakers, you can get an impressive panorama in width.
But the main thing for Iota Alpha, of course, is music. They have low, energetic bass (I can’t vouch for 33 Hz, but it’s really impressive) and a classic top for ribbon tweeters - transparent, light, with colossal spectral resolution. There is a rise in the range 80 - 100 Hz, i.e. in the region of band separation, but interference with lower frequencies is not noticeable. The sound combines real club drive in the bass register with amazing audiophile precision in the upper register. And the middle is no worse - even such a complex instrument as a violin is presented reliably, with “rosin” and characteristic micro vibrations. The snare drum is good - the blow is sharp, bodily, with filling. Of course, cone control is amp dependent, and with proper damping, the Iota Alpha's attack doesn't drag or boom.
In general, these acoustics are capable of sounding a fairly large room, and not just as a background, but for picky listeners at some important event.

Near field
For testing, I simply installed the “iotas” on my desktop and connected them to the well-deserved, but still full of lively energy, integrated amplifier Pioneer A-404R. The source used was a MacBook Pro laptop with an external NuForce Icon DAC.
Let me clarify right away that a distance of about 15 cm separated the speaker from the back wall, and thick cork pads were used as a vibration decoupler from the tabletop. This configuration more than corresponds to the factory documentation, which provides, despite the rear-facing bass reflex, installation in a space limited at the rear, such as bookshelves.
I must say that for a couple of years now, the role of near-field monitors for background music has been played by speakers of approximately the same size, but in plastic cases of a closed design. In other words, I was not spoiled by bass, especially in the modern “multimedia” sense of the word, and was accustomed to being content with the very top in the sound of double bass and other bass instruments. True, the tops are fast, collected and quite clearly detailed.
Diet and warming up
After such a diet, the sound of IOTA sounding in a familiar environment surprised me, to put it mildly. The fullness and depth of the bass seemed simply immense. Although, after the refined dynamics of closed boxes, the bass-reflex character and specific harmonic composition of low frequencies, of course, made themselves felt.
Before drawing any conclusions, I decided to warm up the acoustics properly, because although I received a pair that was not completely unplayed, the instructions clearly mention as many as 200 hours of mandatory warm-up.
The cases are extremely well assembled and covered with matte paint.
By the way, keep in mind that despite its compactness, with a sensitivity of 84 dB/W, this acoustics will not become a light toy for any amplifier. And this fact must be taken into account when building the system.
After warming up, the sound was noticeably harmonized: the mid-bass became less inert, and the vocal range expanded considerably. Surprisingly, in the sound of the kids, the characteristic features of the British sound really began to be discerned - accuracy in the presentation of timbres, detailed, but not emphasized by a thick line, sound of strings and brass.
However, the psychotype of a prim, buttoned-up gentleman in patent leather boots and with an umbrella turned out to be one hundred percent alien to the speakers. They play brightly and energetically, filling the space with impressive volumes of bass against the backdrop of a volumetric and detailed musical canvas at mid and high frequencies. And this should be credited to the ribbon tweeter with excellent microdynamics and the crossover, which works almost seamlessly.
The ribbon tweeter with a small horn is designed specifically for vertical placement, so do not try to place the speakers on their sides - there will be no sound
Nevertheless, the differences in the temperaments of the midbass with a rubber suspension, which is also loaded with a powerful bass reflex, and the ultra-light ribbon membrane are still felt at times. To the ear, this effect is reminiscent of the work of the 2.1 set: the bass, in which you do not experience the slightest lack, is slightly enlarged and isolated, and the main musical picture is light, detailed and voluminous.
As for the music scene, it turns out that its character largely depends on the installation method. If the speakers are turned with their tweeters outward, the sound takes on additional spatiality and lightness. If the tweeters are moved towards the central axis of the system, the sound becomes more focused and specific. It is not difficult to guess that the first option is more suitable for dubbing the entire volume of the room, while the second is preferable for monitor use. Accordingly, when working “for the whole room,” it makes sense to use standard steel stands, each of which rests on three adjustable steel spikes. The bass in this case will sound much more collected than on a shelf or on a bare table.
By the way, at our own recording studio, in which Neat Acoustic employees periodically record tracks of their own performances, IOTA is also used for control listening.

Test of the Naim Uniti Atom player-amplifier and Neat Iota acoustics: stereo of a new era. Stereo & Video, September 2022.
The couple that will be discussed today, in my opinion, is one of the most unusual and striking phenomena in modern Hi-Fi.
This is exactly what a high-quality audio system aimed at a mass audience should look like. After all, today it is forced to compete with music centers and Bluetooth speakers - in terms of convenience and compactness, of course, and not in sound. And the Hi-Fi manufacturer who can do this first has every chance to expand the ranks of its fans and customers. On one shelf
Perhaps it’s time to formalize my thoughts regarding the current Hi-Fi system format today into one simple and understandable slogan: “Everything should fit on one shelf.” This thought just came to me when looking at my own system, which was located on one long wall shelf, purchased for this purpose at the IKEA store. A pair of shelves on the edges, between them a digital source, a portable DAC and a compact power amplifier (volume control is carried out on the source, through the application). We don’t take the server, which is the source of content, into account, but if there was a need to place it next to the rest of the system components, there would be no need to expand the shelf - a two-disk NAS does not take up much space.
A standard stand for Hi-Fi is, in principle, not particularly relevant
Don't think that I'm bragging about my setup, I just want to draw attention to the fact that for a high-quality Hi-Fi system it is not at all necessary to fill the room with equipment. In modern realities, many components are not necessary; it is rather a matter of habits and personal preferences of the system owner. If you ask me if I’m happy with my system, I’ll just say one thing: it could be even more compact and convenient, and it could sound even better. And here we come to the very essence of the kit that will be discussed. The Neat Iota acoustics and the Naim Uniti Atom all-in-one device can, in my opinion, cover all needs in terms of functionality and sound quality. And from this moment we will begin in more detail.
Separate components
The Uniti range of components from Naim is built on the principle of combining a large number of functions in one device. Following the laws of the old school of Hi-Fi, such devices should be declared “combines”, not worthy of attention, and forgotten. However, we think more broadly and are not averse to figuring out whether this is a “combine” with a bunch of problems caused by the close integration of several components within one, or a serious High-End device, which Naim components have always been.
Display quality is the envy of smartphones
Uniti Atom is the most compact device in the ½ format, so inside it the developers effectively used every cubic centimeter of space. At the same time, they abandoned the idea of placing all the circuits on one motherboard. In fact, there is a layer cake of boards installed there that have different purposes: a separate power supply board, a separate digital part, a separate pre-amplifier, a separate power amplifier.
Even when paired with a server, the system does not take up much space
The power supply is based on a large, and for the size of the Atom, I would even say, a huge toroidal transformer, which has separate windings for powering various blocks and boards installed in the device. All boards are shielded and vibration-isolated from each other, and the signal from one board to another passes through a balanced connection.
The issue of vibration isolation in Uniti components, as in conventional Naim components, is taken to the absolute level: all connectors are not rigidly fixed in the housing, and only “bananas” can be used to connect speaker cables. Adepts of analog sound will certainly be pleased by the fact that the amplifier used here is classic, with class AB circuitry, made in the best traditions of Naim (or more precisely, borrowed from the Nait model).
All connectors, according to Naim ideology, are not rigidly attached to the body
Wi-Fi in Uniti Atom is implemented in a special way. In addition to the shielding of the module itself, which is quite appropriate in this case, a patented design of a dual Wi-Fi antenna is used (it uses one of the side radiators of the device at the same time - as a radio wave diffuser and as shielding to protect against interference).
Classic and modern
As you can see, the internal layout is essentially a reimagined Hi-Fi classic. Traditional circuit design, division into blocks (even within one case), shielding, vibration isolation, balanced connection.
However, much more interesting to me were the phenomena of our time. Studying the hardware, it is easy to notice that the device was created from scratch - it does not, say, have amplifier modules from third-party manufacturers or standard network player boards. In fact, Naim engineers independently developed the mini-computer and wrote their own software for it. This is not an easy task, and judging by the IT market, not every manufacturer experienced in this area copes with it perfectly. This takes into account not only issues of convenience, but also issues of quality.
The aluminum radiator is also an integral part of the WiFi antenna
The front panel has a large, bright and truly high-quality display that displays album covers. It turns out very clearly, and the built-in proximity sensor allows you to turn it off and on automatically. The large volume control, familiar to us from Mu-so devices, is very convenient. However, the adjustment process itself is not digital. A digital control knob and an equally digital application ultimately control a discrete analogue control, similar to that used in the Statement high-end amplifier.
The main control is carried out using the proprietary Naim application, which was and remains one of the best in terms of ergonomics, design and information content. The updated version has expanded the list of supported online services, but the basic set of capabilities remains the same.
With a great app, Naim doesn't forget about traditional remote controls
Uniti Atom plays music from home servers, including the proprietary Uniti Core server, works with online streaming services and radio stations, reads audio files from flash drives and external hard drives, has analog and digital inputs, as well as Bluetooth and AirPlay for quickly connecting mobile devices. The only thing I was missing was the ability to play music from a gadget on which the application is installed through the application itself, as is implemented by other manufacturers.
There are more than enough settings, even the background in the interface can be changed
But what Naim can boast of is the ability to load information about the album or track being played into the main playback window. This, in my opinion, completely compensates for the lack of physical media; a digital booklet from the Internet turns out to be even richer than a paper booklet from a luxury CD release. But I won’t go too deep into this - it’s better to evaluate such things from your own experience. In addition, we should also mention the possibility of combining several devices of the Uniti and Mu-so series into a multiroom system and support for the ZigBee protocol, which allows integration into a smart home.
Where does the sound come from?!
Iota is the smallest bookshelf speaker not only in the Neat range, but also in the entire Hi-Fi market. However, they should not be considered as a microsatellite, unable to work without the help of a subwoofer. The whole point of this model is that it is a complete solution for listening to music in a small living room, bedroom or office.
It's hard to believe that these babies provide such a large sound picture
Unlike older Neat models, Iota does not have isobaric inclusion of the low-frequency driver, but it does have its own tricks. Low frequencies are emitted by one miniature polypropylene speaker with a 100 mm cone. In order to get a sufficient amount of bass from this baby, quite traditional solutions were used at first glance: an increased stroke and a bass reflex.
However, you cannot achieve truly deep bass and high sound pressure with such means - you cannot fool physics. But human hearing can be deceived, so the developers increased not the depth of the reproduced bass, but the number of upper harmonics of bass notes. Thanks to this, the listener gets the feeling that not only the upper harmonics are heard, but also the real bass.
The bass reflex and a pair of terminals hardly fit on the rear wall
But as far as the quality of high-frequency reproduction is concerned, there are no psychoacoustic tricks - it’s pure physics. The vertically positioned 50mm ribbon tweeter has all the advantages of planar technology: smooth tonal balance, low distortion, excellent detail and dynamics.
The placement of the tweeter with the midrange/woofer on the same horizontal plane is not accidental. This way you can control the direction of the sound. The close proximity of the two speakers provides better mixing of the sound waves they emit and makes the sound direction asymmetrical. By installing speakers with tweeters facing outward or inward, you can obtain completely different character of the sound stage and varying degrees of sound distribution within the room.
A few words about beauty
It's time to pay attention to system design. And she looks, in my opinion, absolutely amazing. I don’t see any analogies with traditional Hi-Fi. Everything, from the location of the speakers on the Iota facade to the huge volume control on the Uniti Atom lid, looks unusual and will be remembered for a long time.
The location of the speakers is not accidental; this way the direction of the sound is better controlled
In my case, the bright red color of the speakers also added to my impressions. This system can decorate the most luxurious office and the most sophisticated bedroom. Need I say that the workmanship is impeccable? The display of the Uniti Atom will be the envy of most smartphones, and touching the volume knob, which gives a feeling of smooth rotation and large mass, can charm even a person who is very far from the Hi-Fi industry. This set is a thing that you want to have, regardless of the sound quality and our other audiophile things. However, the system has some kind of sound!
Hi-Fi, feng shui
It’s worth starting a conversation about sound with a lyrical digression about the features of acoustics. The thing is that these seemingly harmless kids turned out to be quite capricious in terms of location in the room and in relation to the listener. We managed to figure out the location of the tweeters quite quickly. The optimal installation is with the tweeters facing inward and the speakers facing the listener. This is how you can get a wide scene, with good depth and natural stereo images. I would also like to note that placing tweeters at ear level or ear level with tweeters gives a noticeable increase in sound quality. So if you plan to listen to Neat Iota in an adult way, as the Hi-Fi canons dictate, keep this in mind.
Signature recordings from Naim Records are worth listening to
If the system will be used for background sound, and the task is to fill the room with sound, it is worth turning the speakers so that the radiation axes are parallel, and perhaps even swap the left and right speakers or place them on their sides.
But that is not all. Neat Iota also reacts very quickly to the location in the room, or more precisely, the distance from the wall. Even when the speakers are on stands half a meter from the wall, moving them literally 5-7 centimeters gives an audible effect in terms of the nature of the reproduction of low frequencies. It's hard to believe, but if you place them too close to the wall, there can be a lot of bass.
Great in small
All the experiments with acoustics described above remain behind the scenes when you come to listen to an already installed set, and it is precisely this first acquaintance that is guaranteed to leave an indelible effect. Listening to a system with a very clear, dynamic and quite mature sound, you involuntarily look for a full-size stereo pair or at least a small subwoofer hidden somewhere (by the way, the Uniti Atom has a subwoofer output, and organizing a triphonic on its basis will not be difficult). A simple check shows the integrity of the experiment: one component and a pair of microspeakers play.
The character of the system's sound was quite soft, neat, with enveloping warmth in the lower mids and bass, as well as extremely clear, transparent and well-balanced upper ones.
And the developers didn’t forget about beautiful music visualization
And then, as usually happens with a good-sounding system, the test tracks begin to be sorted from one to another in order to reveal the limit of the possibilities. After all, it can’t be that absolutely everything plays perfectly! Acoustic music, vocals, light audiophile jazz, popular and simple academic music from different eras - this is what the combination copes with almost perfectly.
The system was somewhat puzzled by heavy music, which sounded generally good, but it no longer lacked intelligibility in the low-frequency range. Another way to load the system is to play progressive rock or free jazz. Layering complex rhythms of bass, drums and percussion did not always develop in the usual way. At the same time, straight rhythms, fast or slow, sounded absolutely clear, regardless of whether it was an old AC/DC record or a modern dance hit.
There could be an HDMI port with ARC support under the flap, but you'll have to pay extra for that
Speaking of dance music: this set coped very well with EDM, and the sound character was ideal for loud listening in a city apartment. There is a feeling of a huge booming bass filling the dance floor, but there is no thumping in the chest or the clinking of dishes in the cupboards. Therefore, the neighbors will not come without an invitation.
conclusions
At the very beginning, I wrote that the combination of Neat Iota and Naim Uniti Atom is an example of what, in my opinion, a modern Hi-Fi system designed for a wide audience should look like. From this point of view, the set is wonderful: it looks bright and attractive, does not take up much space, and sounds impressive. Now it’s time to sum it up from the point of view of a modern Hi-Fi lover.
Uniti Atom also has a very decent headphone amplifier
Both Neat Iota and Naim Uniti Atom do not claim absolute neutrality of sound. Both have their own character, more pronounced in the first case and slightly accentuated in the second. As a compact "cabinet" system, this is an ideal, fully complete solution that allows you to get a lot of functions and a lot of sound without taking up a lot of space.
If this is the only system in the house, this kit can be considered more like a starter kit. The price tag, of course, is considerable, but the prospects are good. The Neat Iota can be supported by a subwoofer, and the Naim Uniti Atom has a power amplifier output, allowing the connection of large floor-standing or powered speakers even further into the future.
Advantages:
memorable design, exceptional compactness, high-quality sound, ease of use, good upgrade prospects
Disadvantages:
specific bass sound, acoustics are sensitive to the installation location, no ability to stream music from the application
