Okay, you upraded you AVR/Amp, you upgraded or purchased your dream speakers, you finally got your fantastic sub and when driving it all together you find that it's loud to the rest of the house.. My viewing room is open to another large room that is tiled (echo). Are there ways to trap some sound in the viewing room? Would heavy curtains help? Also, the second floor rolls hard (maybe to hard) when the sub hits. The main floor is slab.. I'm looking for ways to keep the great sound contained or even better than what I have now.. Advice?
