Been quiet lately... too much DIY ?

Hi Andrew,

I remember many years ago, Sinclair (of the ZX81 computer fame)
producted a "flat" loudspeaker.  It appeared to be some kind of driver
attached to a flat styrofoam slab about 1ft square. I only heard a pair
of them once and they certainly lacked bass response.  However multiple
units something along those lines stuck together may be suitable for
your idea.  I guess a lot depneds on what that "driver" was.  Anyone
else remember those Sinclair speakers?  Anyone know how they worked? 

Also, how about electrostatic speaker technology?  I believe they work
by exciting ionized air in a metalic grill (sorry, very simple
explanation of something I don't really understand!).  Seems to me you
could build a large version of this and drive portions of it both
horizontally and vertically from different sources to get the spatial
effect. 
Any takers?  I can supply a roll of chicken wire to get you started
:)!   

Cheers,

Peter
