Hi. My wife and I have a (maybe unique) listening room. There is a small problem, but first to share what we have and that we love it! THE ROOM We had an unused 7'x9' closet. If you are feeling creative, imagine this space. Completely light sealed. Add a silent ceiling PC cooling fan to attic and a couple of strategically located ventilation openings the floor edge molding level. One queen sized futon mattress with a memory topper under its cover. An XVR star ceiling 9 feet up with 12" flat black wall border added to absorb light. 712 stars of 11 different levels of intensity. Lossless audio goes to 4 PC speakers via cell phone 3.5mm (Neutron lossless app) PC SPEAKERS Front: Sony Z623 (2 desktop speakers and a sub) Back: Creative Gigaworks T20, Series II QUESTION Recently I rewired to eliminate a ground loop. I also lowered the speakers to a foot above ground since we are lying down looking up at the stars. There seems to be some kind of audio loss. As the volume goes up, the sound seems to cancel in ways I do not understand. Its not just the base. The sound is clean but some seems to disappear or at best, parts do not scale well with the volume. I don't think the setup can be out of phase since these speakers to not have separate + - connections. Is there some way to optimize positioning of the speakers based on the size of the room and where we are in it?
