I bought the Jamo SUB 650. generally, this is a very great sub. I like the music performance.
However, I found a problem. when I watch some movie, especially in some screen, like people talk in car.
the engine sound is very loud. after I plug the sub, everything is ok.
I used the Denon Audyssey to setup subwoofer and crossline is 80hz.
Do you guys know what happened to my sub?
