I needed a way to tame the highest octave of a small, paper cone full-range driver. I was getting HF distortion on the highest overtones and harmonics and didn't completely like the results when I kept trying lower and lower crossover frequencies. By doping the cone and dust cap in several areas; I was able to "clean-up" the sound of the treble without any X/O. MUCH better sound quality now!

"I have successfully rebuilt my 2 kicker L7's. I just wanted to take a minute and thank you guys for the videos. Without them it would have been a waste of time and my subs would have been paperweights, instead they are pounding better than when they were new!!
Thanks again and have a happy new year!!"
