KT - It was good meeting you the other day.

After taking a look at KT's system, it was a fairly simple problem, He had a mini JL amp rated at 75x4 running his REV8's and also a sub. The amp was gained to the max which created a lot of hisssssssss. I recommended he go back to his retailer and add a small dedicated JL monoblock and run the existing amp in dual mono mode so he delivers 200W to the tower and turn the gains WAY down. Towers where also tuned upward of 150HZ which was contributing to this problem, so on the final tune he should be able to get some more bass out of the speakers by moving the xover point down lower into the 80-90hz range.

Let me know how it turns out KT.

Cheers!
