Thanks Tom for the tip re: the long pillows. At the moment, I've padded the corners in my listening room with some large unused sofa cushions that I've stacked 2 high. They certainly look after the sound issues, but almost ever time my wife walks into the room she says, "Y'know those look like sh**, eh?"
So, for $20 usd ... about $35 up here, (just one of the many un-pleasures of being Canadian), a few of those pollows would really clean things up. And my wife could easily sew up some nice covers/pillowcases for them. Very cool.
My top floor listening room, in general, is a little different, cuz I live in a 1 1/2 story house, so at 5 feet up, the side walls angle in at 60 degrees to the ceiling. It's an 18' x 15' room, and my Kef R107s are on one of the 15' walls, about 2 feet off the front wall.
The speakers are 9' apart, and I sit about 10' back from them, and there is a nice 6' of open, and softened, space behind me.
So when I'm looking at my speakers, the left and right walls angle in to the ceiling, and I have cushions in the corners of tbe front wall, and sound deadening on the side walls at the first and second reflection points.
So anyway, my point is ... I can hardly believe how good the sound-stage is from my very modest equipment. I really haven't spent much, so I figure that it must have something to do with the shape of the room and the way the sidewalls sngle in; eliminating that upper corner issue alonv the side walls.
And really, the sound of any type of music is impressive. Very full, nicely delineated instruments/voices, very forward and very wide; and quite enveloping.
I've arrived at my current setup/placement, by moving the room treatments, and speakers around, a bit at a time, and it's really paid off.
Anyway, I just figure that for the litttle I've laid out in cash, it shouldn't sound this good.
