This box is a variant, or rather a further development, of the Hans Deutsch Poseidon, which was distributed in the second half of the seventies by JWS in the Federal Republic of Germany.
Technical data (source: HiFi Yearbook 11)

- dimensions (WHT): 370 x 560 x 235 mm
- weight: 15 kg
- non-binding, approximate retail price: 998 DM
- Special features: "Eye-catchingly documented by 3 optical-acoustic specials: in front of the woofer system the acoustic crossover to absorb frequencies above 500 Hz, an acoustic baffle lens at the midrange driver to attenuate the intended indirection, and decisively optimised components - the golden horn seems reality - emphasised still by a valuable design (oak / gold-coloured details) ..."
Deviating data from the advertising of JWS:
- Rated power: 80 watts sine wave at 4 ohms.
- frequency range: 32 Hz to 20 kHz
- separate mid and treble control can be lowered by +/- 4 dB
"... With the Poseidon JWS offers a speaker that stands out from the crowd due to some unusual design features. Sonically, its main merits are bass reproduction with impressive volume, a certain fundamental vitality and unobtrusive treble." (Excerpt from the test report in HiFi-Stereophonie 11/81)
