A little overpriced but OK
I liked that you could control the rear channels with the knob, but I really think that you should be able to control all four channels with the knob. Instead of just two channels. But I understand they do that because people use a subwoofer on the back two channels. But if you use all four channels for highs or mids it’s kind of pointless that u have the knob.?? also the little jumpers you pull them out by hand, and they fall out by their self and I’ve already lost one.?
