I should probley know the answer to this but I'm not sure what to do. My wife & I just bought a house in Dec & already my sub has proven to be a small problem. My neighbor, wich thankfully is a good friend of mine can hear my sub in his house wile I'm watching a movie. In the day time It's not any big deal, but I watch movies at night most of the time. He tells me that every time I watch a movie he can hear my sub from time to time, of wich he said dosent bother him, but his wife is in bed early normally around 8 or so. Now before anyone rips me a new one I'm actley keeping things turned down pretty low, in fact well below my normal levels. But two things are going on here first off I don't by any means wont to get any neighbors pissed at me for noise. But secondly I wont to enjoy my surround system. What I really don't get is that in the house it's not loud at all. In fact my wife & kids will sleep all night with me watching movies no problem. Now I guess some of it could be that there just used to the noise but it really isn't loud in the house. Another thing is that our houses are pretty close to each other, I'd say app 30 to 40 feet between the back of mine & his. But again my previous house was even closer to the neighbor & never a problem in the three years I was there. There is one big difference between houses though. My last house was on a slab, this one is not. I have a partial basement, & than a crawl space under my theater room. I don't see how that could make much if any difference as for sound travel, but it did seam to boost my bass in the house compared to my old house. The floor is not insulated in the crawl space, & I have thought about putting some in to mabe help control sound some, but I don't know if it will do any good. I don't know if its just my friend is just being way over sensitive or if it really is a problem, but I don't wont it to become one. Not to mention I would like to be able to watch movies again without having to worry about getting anyone upset or waking neighbors. Dose anyone have any suggestions that might help? I can't afford to blow a ton of money to sound proof the room, but I'm willing to go to some extent to get back the fun of having a home theater. Thanks for any thoughts.
