"I know I expected my bass drum to sound better than the current muffler/damper I have been using, but WOW! The fundamental punch is more present than before, with an incredible bottom end without it being too overbearing or canceling out any of the bass drum upper end. Consistency is the name of the game when you play different venues, but the Kicker has you covered with three removable tubes to allow you to tailor if need more resonance. Thanks Kicker and Sonitus for making my job easier."
