Well my way with words is bad and my audiophile's lingo is even worse but here goes anyway. I have been looking for some new (used) equipement for two channel but until then decided to move my H/K 320 and RT600's around the house a bit just to see what differences my subject title makes. In the smaller room which is 13x11, with the speakers against the narrower wall, they just didn't sound very musical. The bass seemed to get lost and the mids seemed to shout at you. The tweets sounded a little bright for my taste, although that was a common trait no matter where I placed the 600's. I then moved the system to a larger room which is 15 1/2x12 3/4 and placed the speakers against the wider wall. This room has a 6 foot opening to the dining room to the right which I thought for sure would kill the sound. Well the sound absolutely opened up although I had to use a few more decibals compared with the smaller room to get the same sound level. Much more musical and the bass came to life, even for the RT600's. The mids were more neutral and not as forced sounding. In both rooms the speakers were placed 18" away from the wall and the same distance apart, just to the right and left of the 47' widescreen.
Anyway the bigger room gave new life to these speakers (although still a little harsh which I think has more to do with the H/K), but now I am wondering can a room be TOO small for good acoustics? Damn if only I still had the Rotel/Lsi combo to try in the larger room. Incidentally, the PSW303 was much more noticable in the larger room. Perhaps because it had a little more room to breath in the corner (although still too boomy for me) but it works pretty good for H/T.
Well I wanted to post this because I was quite surprised at the difference in sound quality in the two rooms. Let me just note here that both ceiling heights are almost 8' and the smaller room has plaster walls as opposed to dry wall in the other with both having dropped ceilings with the same panels and like carpeting.
OK, stop laughing now. Just that I was quite surprised at the results.
