Twelve most unusual speakers

Twelve most unusual speakers

We continue our series of reports about the most amazing technology - next up is a story about old acoustics, when creating which the engineers did not restrain themselves at all. As a result, it is still impossible to look at these speakers of the past and today without awe. They either came to life straight from the pages of science fiction novels, or came to us from another world.

Empire Grenadier 9000M

This is the kind of grenadier Empire made! The model was produced from 1967 to 1973, it provided a radiation pattern from 360 to 140 degrees (thanks to the use of acoustic lenses). The frequency response was a record for those years from 20 to 20,000 Hz (there is also a “super tweeter” for frequencies from 5 KHz), a 15' speaker worked on the bass, the maximum power input was 100 W. The price at the start of sales is $299.95. The height of the acoustics is 74 cm, diameter is 56 cm. Chunky bedside tables.

Hitachi Lo-D HS-10000

Five-lane giant, produced in the late seventies of the twentieth century. Cellular 30 cm speakers on the bass (woofer and passive radiator), then a scattering of “support from above” - 6 cm, 3.5 cm, 1.8 cm and 0.9 cm. All speakers are unique, with flat diaphragms filled resin. Height – 1.8 meters, frequency response from 20 to 20,000 Hz, sensitivity 89 dB.

The Grundig MONOLITH 190
Genesis clearly takes a lot from this model. 24 speakers and 4 built-in amplifiers in each speaker ensured fully active activation of 188.5 cm giants. The acoustics were produced from 1979 to 1983, their power units had standard characteristics - the distortion level did not exceed 0.1-0.2%. Frequency response - from 20 to 25,000 Hz, the set of speakers included 8 x 17.5 cm woofers for the bass, 7 x 3.7 for the midrange and 7 x 1.9 cm tweeters. One column weighed 83 kg.

Acoustic Research AR9

Acoustic Research AR9 1978 – 1982 releases weigh 59 kg each - and offer a number of such advanced technical solutions that even today there is a real hunt for them at auctions. Two 30 cm woofers emit sideways, their operation is optimized to dampen standing waves up to 200 Hz. The speakers were extremely difficult to amplify for their time - a sensitivity of 87 dB and a drop in resistance to 3.2 Ohms dictated the need to use extremely powerful and stable transistors with them. Frequency response: from 18 Hz (the body volume of 120 liters with a height of 134 cm allowed this) to 30,000 Hz, for this band were responsible (in addition to the mentioned bass drivers) 20 cm, 3.8 cm speakers and 1.9 cm tweeter; Moreover, the latter used liquid cooling technology.

Dahlquist DQ-10

In 1974, speakers cost $395. An absolutely crazy design with a phase matrix of speakers on different planes. The first speakers to deliver a truly three-dimensional, holographic soundstage. The price to pay was crazy amplification requests and limited bass. To create proper support “from below”, it was recommended to purchase a branded passive subwoofer Dahlquist DQ-1W Passive Subwoofer, as well as a crossover for connecting to speakers - Dahlquist DQ-MX1, and then start amplification again. The frequency response of the model ranges from 37 to 27,000 Hz, resistance is 8 Ohms, input power is up to 100 W.

Onkyo Scepter 500

Costing 580,000 yen at the time of release in 1978, these speakers were equipped with huge 38 cm W3801 woofers, the power of their magnetic system reached 11,000 Gauss (low frequency response - from 25 Hz). Further, everything is even more interesting - proprietary drivers D6540 A+H 4003S with a sectoral horn worked on the midrange, then a system of horns and acoustic lenses D3520A, H2014P, AL80 worked on the high frequency, and the super tweeter worked in the range up to 35,000 Hz - thanks to the use of the TW3001 horn. 96dB sensitivity and 120W power input – oh baby, yes! This acoustics could play really loudly – ​​the maximum sound pressure reached 117 dB! Massive cases weighing 97 kg and 200 liters of case volume (with a height of 130 cm) are the finishing touches.

Diatone DS-5000

1984, classic four-way speakers with 40 cm bass drivers (as many as 286,000 Maxwells) and 25 cm mid-bass drivers (honeycomb diaphragm - made of aramid fibers and aluminum). Next they work - a 6.5 cm dome speaker DUD (diaphragm and coil are a single design) with a boron diaphragm, the tweeter (2.3 cm) is similarly designed. The bodies are made of deflector plates (plywood and walnut), the finishing quality is exceptional, but what is special about them? For a second - the frequency response is from 20 to 60,000 Hz, this is absolutely unique for the eighties! The applied technical solutions allow these speakers not only to compete on an equal footing, but also to surpass the most modern examples of High End speakers. Input power is 250 W, resistance is 6 Ohms, and sensitivity is 93 dB. With a height of 105 cm, the acoustics weigh 87 kg.

JBL S119

Yes, JBL were like that. A two-way strip with an omnidirectional study diagram, a bold experiment. A 20 cm 108H bass driver and 4 x 2.5 cm LE20T-2 tweeters were used - they guaranteed a frequency response from 40 to 20,000 Hz with a sensitivity of 86 dB and a resistance of 8 Ohms. The acoustics first appeared in 1972 and were offered for 111 yen, and were re-released in 1988 (positioning was aimed at owners of cinema systems, magnetic shielding of the speakers was added). During this time, it became more expensive - a new model could be bought for 256,000 yen.

Sony ESPRIT APM-8

Square speaker cones are not a fashion, but a necessity to achieve standard sound! Sony released several variations of such speakers in the eighties. Sandwiches made of aluminum with aluminum cores and cast baskets with ring magnets connected to them through four special cylinders are an absolutely revolutionary design. 807 cm2 for the bass, 144 cm2 for the lower middle, 24 cm2 for the midrange and 5.8 cm2 for the treble - all this gives a frequency response from 25 to 30,000 Hz with a sensitivity of 92 dB and a resistance of 8 Ohms. Peak power 500 W, weight of one speaker 102 kg, price – 1,000,000 yen. The speakers were produced from 1979 to 1982.

Pioneer S-F1

Super rarity - and, again, with square diffusers, also located coaxially. In total, no more than 100 pairs of these speakers were produced; the model was produced from 1979 to 1982. Four-way, the speakers are as follows: 40 cm on the woofer, 15 cm on the midrange, 6 cm on the treble and 2.6 cm on the super-tweeter. 94 dB sensitivity, 150 W input power and 8 ohms resistance. Price at the start of sales: 850,000 yen.

JBL Paragon D44000

Fetish of collectors from all over the world. Owning these speakers is like having a Rolls Royce from the 1940s in your garage. Produced from 1957 to 1984. the cabinet contained a horn stereo system that produced absolutely magical sound. A three-way unit with 96 dB sensitivity (frequency response up to 15,000 Hz), a resistance of 8 Ohms and an input power of 125 W had branded speakers on board: a LE15A woofer, a midrange driver with an acoustic lens 375 and a horn H5038P, a tweeter 075 (also with acoustic lens). 263 cm wide and 72 cm high, weight 316 kg (even the support legs are not four, but six)! It was the most expensive mass-produced acoustic system until the early eighties of the twentieth century.

Technics SB-10000

Not a single selection of super-speakers of the past would be complete without them! The company's 1000-series set was offered in 1980 for 5.45 million yen (the acoustics could be purchased separately for 2.5 million yen; there are reports of 1.2 million yen, but, apparently, this is the price per piece) - system for multi-millionaires. The technological solutions used still cause “shock and awe” today. The EAS-35HD04SA tweeters with a boron diaphragm are housed in a horn and operate up to 35,000 Hz. The EAS-10HM03-N midrange speakers are also enclosed in a horn - their polar pattern extends over 150 degrees. The EAS-46PL01S bass drivers work in their own housing (the volume is as much as 300 liters). All horns are made of aluminum and are not subject to aging due to exposure to air humidity. Sensitivity 95 dB, resistance 6 Ohms, power input 300 W, weight of one speaker 140 kg, height 111 cm.
