Seeking: Screw all the electronic answers to your volume problems. None of them allows 'loud.'
When I lived in an private apt. building in grad school, I left a note on all my adjacent neighbors' doors to let me know the best times to use my stereo w/o interfering with their serenity.
Of course, I had to try to be home when I knew they weren't, but it was way better (to me) than a volume compromise.
Eventually, they even left ME notes when they were going to be out of town. Then again, I was having sex with each of them, so maybe that was a mitigating factor?
