I had a customer mention to me that his room is too hard and "echoey" and the top end on his speakers are a little too bright. He has scatter rugs on a hardwood floor and some drapes but he feels that this is not enough to stop reflections. Now depending on your WAF, (wife acceptance factor) who may or may not like this solution, you could try some acoustical foam. The Foam Factory online has a wide selection of acoustic foam in various styles. They also have bass absorbers if a little too much bass is your problem. I have used their acoustic foam myself. The panels are not too expensive and they kill echos in the room very well. Check them out at the link below.
Some very nice stuff here. One small quibble on the nature of deep bass: most of those vibrations are pretty much immune to casual room treatments (below say... 60 Hz). This does not mean that this foam is ineffective, but that the SOAF (significant-other-acceptance factor) may be of greater importance when the material is placed.
Thanks for the link! Writing for myself, my present need is low, but knowing such a source is a very good thing!
One trick is to have a helper hold a mirror flat on the wall while you look from your listening position; and move it around to where you can see one and the other loudspeaker in the mirror. That's where you put the antireflective foam, if it doesn't upset the room decor too much or if you live by yourself...or if it's YOUR exclusive listening room!
I just iBalled the room and taped a weighted string to about where I thought the ceiling "baffles" needed to be, then gave it a swing. When the arc pointed at the tweets AND my pointy little head on the rebound, I was good to go.
Bob, Unless you're a stone-cold bachelor, which I think you're not, either, this topic should be banished from the Forum. It has ignited too many fights between the humble toob-o-phile and She Who Will Be Obeyed. Unless, of course, you've got an off-campus man-cave.
