JVC brings out the spherical speaker...again

The first one was in 1967.

Not exactly a floor-stander.

I would think that you could get some nasty room reflections with these

Common, we do not have to as far as JVC, but go to the Bose 901s.  Again, eventhough there might be room reflection issues, what about those speakers that claim to be ommidirection, such as those uber expensive MBL Ommidrivers?

The mirages and others like it such as the Ohm walsh models are also omnidirectional - but not as omnidirectional.  These supposedly have constant frequency response over a greater frequency range than do the solutions such as found in the mirage and ohm designs.

They would provide the near perfect point source for proper imaging (if matched to an original two mike setup that no one uses in the recording industry).

Wonder what the frequency response is, especially in an apparently sealed cabinet?  (I own single driver speakers, so know of the challenge to find full range/quality drivers.)

Wonder how the 11 drivers are wired?? (Series, parallel, or something crazy like Bottleneck the speakers)  What would the overall resulting efficiency, average/peak impedance look like?

Wonder how the back waves are addressed.  Would they all cancel each other out (if properly wired)?  As cones are too thin to be acoustically transparent, the resulting backwave would come back out through the cone as most any box design.

this quote :

"Yup, Design Acoustic D12 was also a "dodecahedren"(12 sided) shaped speaker in 1972 (+or - 2 years. But it was bigger and I am sure better (10" woofer, 5" mid and 9 tweeters. The 12th side was a port for the woofer. They were great but no one liked the looks so they fad e d a w a yyyyy"

the D/As were good, not super, but better than the previous jvc that hung and was smaller.  its too bad they werent more successful, a more developed unit would have been interesting.
