So I really want to know if this is true. I was jamming with my brother who plays drums, because of this I had to turn it up quite a bit to try and hear myself. After my 'rents got back from they're walk they told me to turn it down because I was cracking the walls from the vibrations. It seems reasonable, but so many bands play at houses that still stand today.. so does this really happen? I was playing just loud enough to hear myself with the drums, through a 4x10. I didn't know where to post this thread either, so if it's in the wrong spot I'm sorry.
