Axiom Home Page Forums General Discussion Home Theater Subwoofer hum

You are exactly right, the best setting for me is around 10 and there is no audible hum either connected to the recevier or not. I only noticed the hum when it is turned way up -- and not in use since that would knock some walls down...But the hum is a little louder when connected to receiver (again only at the higher amp levels (>2 clock)

I guess I was curious to know if the humming at high amp levels is normal?
BTW - the hsuforum does not cover much of this stuff which is why I am relying on you guys -- thanks for being patient with me.
