Here is a photo of these speakers D-12 Design Acoustics
Vintage Speakers
Anybody out there remember the company who made the omni-directional speaker (was actually a dodecahedral disign). I believe it had 12 sides. I think they came out in the mid 70's. Were a unconventional-radical design. I am trying to find out info on these-anybody who can shedd light on this for me would be greatly appreciated.
