I suspect the real problem is that you're playing the system with the bass
jacked up every time, all the time. Your neighbors might not object so much if
the loud bass were only occasional.

You wanna hear a really weird story? A friend of mine used to live in an
apartment with very thin walls. When he sat near the wall, wearing his Stax
headpnones (!!!), the old lady who lived next door complained about the sound!
