I think I figured it out, with a combination everyone advise. The right speaker I reconnected each of the drives, but I think the issue was a weak connection on the rear terminal, with the nut.
The left speaker, the bottom woofer is blown. Visibly it looks good, but it is distorting. Any suggestions on repair or replacement? Where do you recommend to buy a replacement?
One a side note, my matching sub has a consistent low hum. I have tried different outlets, its plugged directly into the wall. I have tried the ground delete wall adapter....
Thanks again!
