JVC GB-1E
(1970s)

Here is something which never sold well : suspended loudspeakers.

Grundig had its own Audiorama 8000, JVC had the GB-1 and the GB-2 and others had their own. Elipson was the first anyway to have taken advantage of the round shape - no diffraction, easy omni-directional spread of the sound and very little resonance.
Even if not high-fidelity, Toa sold millions of "sound balls" throughout the world - many are still hanging around when you walk in this railway station or that public building.

Each 11kg GB-1E has four 5" free-edge woofers and two "globular diaphragm" 2" tweeters. The two halves are hermetically sealed and, inside, a special acoustic material prevents standing waves from... standing ; a 5901 floor stand was available if hanging wasn't possible.
Easy to feed with 93dB of efficiency, a 5kHz crossover and 8Ohm load ; maximum power handling is at 80W, or 40W RMS.
