Thanks Star/Harosha,

I checked out the auralex website. Good stuff. Not sure if I'm going to spend that much money on sound dampening stuff (I feel it's going to be up there in the hundreds of dollars). I know this for sure that I don't play music as loud as my neighbor does. I can't imagine my 20watts sony/5 inch full range boston acoustic would rumble all the walls. I'm a really nice neighbor...I don't play that loud anyway. I just thought if spending less than 50 bucks (I know..i know..i'm a cheapskate!) can reduce the "possibility" of my sounds travelling through the wall, I'd do it. Heck, even I can hear her sometimes playing her collection of country music when she cleans the house or whatever (just the bass though).
