I've recently come out of retirement after 6 years away from my drums and needed to reskin my Sonor Delites - 22, 12, 14, 16, including the kick drum reso head. When I was looking at rings for the kick drum port hole, I realised there isn't a whole lot of price difference between one of these and a pack of generic plastic rings, which are really only good for aesthetic purposes. I've always hated any kind of muffling or laundry pile in my kick drum and so I was eager to try the Kickport which I've read works better without any kind of internal dampening.
Installation was incredibly simple, easier to do than describe in writing if anything, and the chrome finish looks fantastic against a Remo Fyberskyn.
Sound wise...WOW.. it simply has to be heard to be believed. My kick has always been a beast, but the Kickport really adds to the low end thump. The sound is clear, focused, and, and well defined and still delivers fantastic results when mic'd up in studio conditions. I have yet to try it in a live environment with a mic, but I really can't wait for the day as I'm sure this thing will rock any venue around.
