Thanks Guys,
Just got off the phone with Axiom.
The problem is my tiny S.W. is being "overwhelmed". The answer was to turn it down a bit more when watching the more noisier (deep bass) movies.
Its only set at 10 to 12 right now and still does it.
I will have to reduce the DB output on the receiver from 0 to maybe -2.
The other alternative was get a bigger sub. The EP175
Thanks again,
Neil
