I had a 2.1 THX unit I purchased in 2001 go down. I purchased a new replacement about 6 months ago.
My problem is I notice an amazing amount of static from L and R speakers.
After I purchased the new unit I dug into my old unit and found out the woofer speaker foam had deteriorated .
I purchased a replace woofer and put that unit in my garage.
I don't seem to have the static on that unit.
The static is horrible on the new setup
