[QUOTE="Brad Weber, post: 109636, member: 114"] Re: Lumbar Array? Based on this, [url]http://www.jblpro.com/press/june07/SAVA.pdf[/url], it seems that the venue apparently already incorporates some form of physically variable acoustics and perhaps some of the wall speakers referenced by Ivan Brusic may be the JBL cinema surround speakers installed as part of the cinema system upgrades. The comments Andrew quoted referenced only delay, not reverb. My guess is that since they apparently have two 'layers' of surround speakers, probably one serving the center of the room and one the areas closer to the walls, he can have a shorter delay for the speakers covering the center of the room to try to make that perceived as early lateral reflections. But with just delay of the direct signals they would seem to be be more discrete rather than diffuse reflections. [/QUOTE]
