No offense. When u got the correct subwoofer setting, it sldn't annoy your neighbour. It just blend it right and doesnt go too boomy.

I did check with my neighbours. They dont seems to be disturbed by it. Apparently, they didnt know that I was blasting at high vol. 200W powered 12" sub with dual 10" woofer spkr (that makes 4 x 10") firing away. No prob. Tuned using Radioshack SPL meter.
