Summary: I got this sub as part of a HTIB setup. My biggest complain about this sub is that it has serious crosstalk issues. Its acts like a radio, picking up some local transmission and puts out really annoying muffled voices. I haven't been able to pin point the exact resonant frequency for the crosstalk (need an RF signal generator for that, which I dont have), but I guess the amp portion inside is not properly shielded. Deal breaker for me.... and GOD ..
