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.\n\n\nCome on man, everyone knows that to negate a 28db null at 50 Hz you need to use 28 foot long square 12 gauge cable runs since it's 1db gain per foot!
