Square cables tend to be REAL bass heavy since the bass transmission signals collect in the cable corners. The longer the run, the bassier they are. I was able to fill in a 50hz null that was 28db down, by changing from 10’ round cables to 27’ long square ones. If the null was in the 30hz range I would have used 10ga as it’s more effective down low. Square subwoofer cables have also supercharged my subs. Sooooo much cheaper than buying new subs too.
