Depth Imaging


My KEF 104/2s are 92" apart and flank a Sony 36 XBR. The fronts of the KEFs are 38" from the wall, 35" from the side walls. Frequencies below 80 Hz are shunted to a Velodyne HGS-15. I improved depth imaging for stereo by removing two equipment cabinets that sat on each side of the XBR and between the KEFs, and removing the cabinet around the XBR. Horizontal and vertical imaging are excellent.

I want a larger video image to better match the large sound stage. Front projection is an obvious answer that would improve audio depth imaging further, but I'd need a flat panal display behind a pull down screen so we don't have to sit in a dark room for regular TV viewing. An alternate is a flatter monitor that sits between the KEFs, e.g. a plasma or the new 60" Sony XBR Qualia spin-off rear projection.

This raises the essential question of this post: Is it the mass or the relective surface area between the speakers that interferes with good depth imaging? That is, would a 60" plasma monitor interfere any less with depth imaging than a 60" rear projection monitor? My knowledge of acoustic propagation and its effect on depth imaging is not up to the task, so I'm seeking help.

Donbellphd, I suspect the plasma will intefere less than a rear projection set. That is just a suspicion. It may turn out that the deeper rear projection might just break things up a bit. There are now screens from Sony and DNP that enable front projection with some ambient light. These screens are more expensive than typical ones. I suspect that a good projector and one of these screens would be less expensive than a 60" plasma. I suspect that such a projector set up would off the best sound, especially if you could draw drapes over the screen.
