World`s first “head to head” bass drum muffler. The Kicker is custom designed for all bass drum diameters and depths. It is made from Polyester foam with a special structure that yielded the best results for the Kicker. Kicker dampens the rear and front bass drum head at the same time and is produced proportionally for all bass drum sizes, that means the volume of air percentage is the same in a small or big bass drum. Its design and material gives a clear sound in low frequencies, while muddy mid frequencies are being absorbed. The result is a powerful and very focused sound.
