from w/w CARPET to WOOD floors

I've read a fair bit on room acoustics and balance can be one key. So I might agree with RW, what are your other five major surfaces like in terms of absorption/reflection?

But Zd542 asks the most basic question - do you have problems now or are you just restless to change something?

One point I've read from several sources, wool is one of the best absorption materials. It is better than most any synthetic. So your berber with thick pad would seem to be a good choice as part of the desired absorption percentage.

I stuck "vibra pods" under my speakers on wood floors and they sound amazing...this was after decades of spikes, and it seems that some high end speakers come with what they call "decoupling" dampers so there could be a trend away from spikes...for room treatment you can also try buying thousands of pods and stick them all over your walls and ceilings, but I find that hurling large amounts of freshly cooked pasta against the walls works well, although you have to keep at it as it dries out and falls off.

I removed four flat 2' X 4' absorption panels yesterday, and liked the results. The sound opened up a bit, and had more emotion. SOME recordings were slightly dry sounding with the panels in place. What I hope to accomplish is more natural sound, which a room being too dead can hinder. Room is 23 X 12 w/ 8ft ceilings, speakers set up on 12' (short) wall.
Sheet rock walls and I have two 4ft X 4ft older RPG-like wood diffusion panels stacked on one another in back/between speakers. Check out my photos on my system page (-:

Wood floors will give you that lively small club sound. I love it. rugs will help with resonace and they look good too!
