"Place the Powerpads behind your speakers to wipe out cone breakup and distortion. Deflex Pads will help tighten up your midbass and improve your soundstage."
I'm going to install some CDT's (my first comp set!!) and i was wondering if i should pay the extra $35 for these kits.
the powerpad is to break up standing waves, IIRC. I haven't put it in my doors but its on my list as I hope it will eliminate any chance of standing waves or dull midbas in my doors.
