I added a second run of 12 gauge to the mids which is effectively like a 9 gauge cable. That seemed to do the trick in getting my midbass back! The highs are still a little rolled off but I’m going to hold off on doing anything. I’m sort of apprec...

Group delay in subwoofers

Speaker Cables and Carpet
Correct, the cables are under a layer of carpet. I’m pretty sure cable risers would help a lot, but then I would lose the clean look I’m going for. Are there other solutions than cable riser? Or is there a way to incorporate cable risers and keep ...
