drdna,

The subject of room reflections is kind of completed topic but form what you described I do not think that your problems are there but rather in some kind of bug of your system that you will discover soon. Meanwhile, I would disregard any room issues at this point besides the macro-poisoning of you your speakers. Well, yes and no….  There is one thing in the room reflection that you might look but it not because it’s related to your spastic case but because it related to 99% of all hi-fi installation and unfortunately widely disregarded by the people who love to talk about room acoustics and at the same time have crapy sound in their listening rooms. You see, handing the sexy diffusors and resonator is affective to one or another degree but there is one HUGE subject that unfortunately completely ignored: the listing room ceiling. If you do not has a very high ceiling that produce 1 second reverberation time at 5kHz then the reflections form this ceiling should be killed or “retouched”. Those “glossy” large horizontal surfaces produce an acoustic fog that I found very-very annoying and any clapping echo test would instantaneously portray it. There is a very-very easy and very cheap way to deal with it, without deading your room, still kipping it “live” but to killing the unwanted ceiling’s acoustic fog: introduce something the I call the ceiling’s sails. The ceiling’s sails are the none-horizontal layer of soft fabrics that located angularly to the surface of the ceiling and located at the location of primary OR secondary reflection. The sq footage and the angle of the sails could be tuned to the specific room… unit … it would be pleasant just to talk in the room. They it is a time to place the speakers in there. You could ran RT60 at high frequencies or do it by your ears but 99% of the playbacks out there are very ceiling-fogy… Here is a idea how I deal with the problem I my own listing room.

Do not over-sail your ceiling though….

We have found that a very heavy speaker wire, or multi stranded really damage the sound. We have had best results using a single strand thin gage magnet wire for best results.

Rich, could you elaborate more on the heavy speaker wire and damage to sound

Rgs,
