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

Thanks

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.

for some reason they make me want to say ...


EXTERMINATE!

Neutron7,

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

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

I bet they are meant for a large room!

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

Precursors to Bose's "omnidirectional surround"

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.

Really nice work, John, even prettier than those:

I heard these in a Fiji Duty free store in the 70's. Typical store, totally crammed full of mainly Jap electronics and HiFI gear, but including European stuff. I bought a Lenco turntable and a Pioneer amp both which I still have. In fact the Pioneer forms part of my test rig.

Not the best conditions to listen to speakers, but from what I remember, the Sansui speakers of the time were better than most others on offer. (Sansui quality at that time was far better than their modern stuff, - up market priced, and very reliable)

The Akai's (of all sizes), were probably the least favoured speakers by local expats. but their tape stuff was good.

The pyramidshaped loudspeakers were actually designed and made by a Swede called Bengt Larson!The model nr is Larson LP720.

I do know about them since I have a pair myself!There should be a plastic badge"Larson" at the bottom,but since they easily come off, you don't see them very often in the pictures.Palisander is also by far the most common on these in original.The drivers,the feet,the metal net on top-everything exactly as the original!

His pair looks exactly as the genuine Larson,which makes me wonder-why does he say that they were made for him?Of course it's possible,but I wonder......
