I had my entire room's ceiling sprayed 1" thick with bleached-white cellulose insulation fiber. This is the same gray stuff found on warehouse ceilings, etc. It improved the echos & reflections considerably & was not very expensive, although it was quite a messy install. The cellulose worked well enough that I didn't have to completely hide the beautiful hardwood floor under full carpeting; a large wool deco. rug centered in the room does nicely. Also hung some artwork and various hook rugs on the walls all around, plus the curtains & stuffed furniture all adds up to some pretty decent room treatment and looks quite natural compared to the various treatment contraptions
Hardwood floors vs Carpet
I am about to pull my carpet flooring to install wood flooring in my home. I had a non-audiophile over who stated that the acoustics will change with the addition of wood vs carpet. It dawned on me that he was likely correct. Anyone know what changes in sound could be forthcoming with wood flooring? I have recently got my system to sound like ive alwasy wanted and hope this home improvement doesnt serve to be a audio downgrade.
