Default Strange design. Has anyone heard them?

See

Weird in the extreme. Can anyone outline the design, history etc of this design?

Thanks

Doug

Very interesting looking things. Looks like an omni directional setup, but hey. Might be worth having a bid just to find out exactly what they are.

Neutron7,

I wonder how many people in here know about Doctor Who?

Cool looking speakers, I bet they are meant for a large room!

Yes, right in the middle of that room. Actually you only need one per room

I have a friend who in the early eighties had also designed such a speaker. The footprint is an octagon. The top and bottom had a woofer each, connected with a force cancelling rod. Each of the side faces had a midrange and tweeter alternately placed. His theory was that all of this amounted to one virtual point source, right inside the middle of the box. He called it omnidirectional speakers.

When played with a good source and a good amp, the imaging of these speakers were stunning; yet the sound was very spacial and relaxed. There was absolutely no smearing, despite the many sources. Ofcourse, he had a bunch of papers which showed his math behind the design.

I certainly hope my Hexagon project on the Single Driver Section looks better than those.
