I have had kick ports on three different drum kits now. On a 22x18, 16x16 and now a 22x14 and it has made such an impact on each kick drum. I went for the chrome kick port this time as I have an acrylic kit with chrome hoops on the bass drum, and they tie in together perfectly.
Installation can be a bit tricky, this time I had to remove the batter head in order to set the kick port in place. But it's worth the hassle once you get to hear the result.
