Hi all - I could truly use some advice. We've just moved into a lovely downtown condo which is very soundproof - with the exception of the vibrating sound of our neighbor's subwoofer in his home theatre. If he's listening to music, we get the bump bump whzzzzzzz vibration, and if he's watching movies, we get wall and floor shaking and the sounds of war. We've talked with him a couple of times, and the only solution seems to be putting the subwoofer on night mode, which he's done for the last week and a half. However, he came over last night to discuss his feelings that he should be able to turn the subwoofer on at "reasonable hours" - basically, from 10 am to 10:30 or so pm every day. His feelings are that he's had the subwoofer for 4 years, he didn't have a complaint from the person who lived here before (he was here for about a year and apparently had his own stereo which he blared), and he should be able to listen to his music and movies with the subwoofer on because that's how he likes to listen to it. He also suggested that we could fix the issue by "insulating our walls," which a google search on the subject does not seem to be something that would work. We feel like, while we understand we'll hear some bass noise occasionally even with the subwoofer off (and we are not complaining about that), that the subwoofer is so invasive and irritating with it's constant vibrations that we just don't want to hear it all day on a Saturday, reasonable hours or not. Frankly, we don't want to hear or feel it at all. We are not saying he can't watch his movies or listen to his music - even quite loudly - we just don't want to hear the subwoofer (which is pretty much all we can hear). However, we have been 100% willing to try to find a solution here. I have spent lots of time online trying research ways to deal with this. The only thing I can come up with at the moment seems to be something called a "Subdude," which will get the subwoofer off the floor. We've even offered to pay for it. The problem is that the Subdude seems to work more to reduce noise conveying downstairs, not next door. The other solution that I can find involves him moving his subwoofer to another wall, but he doesn't seem to be too willing to do that. Does anyone have any solutions that could help us stop the subwoofer noise? Is it a major inconvenience for him to have the night mode on? Is there a huge reduction in listening enjoyment? And is it reasonable for us to not want to listen to the banging vibration of the subwoofer, even at reasonable hours? One of the problems is that I am a coach and I often have coaching sessions at 7pm or 8pm at night, and the buzzing thump of the subwoofer isn't really conducive to being fully present for my client. This is causing a HUGE amount of stress for all involved, so I would truly appreciate any expert advice anyone could give. Thanks so much!
