There is this particular speaker that I have an issue with. It is in my living room and it seems to me that the bass frequency is more powerful than the treble frequency. The other speakers sound great.
The first thing I would try, would be switching the two, and see if the problem reverses itself,
or stays the same.
Johhny, I am referring to the front mains. I have tried switching the two but it remains the same. My thinking is that there could be a problem with the wiring connections.
