Sonitus Kicker 2.0 For 22x18" Bass Drum.
The Sonitus Acoustics Kicker is made from a special polyester foam, and is incredible durable. With proper care it should last for the lifetime of your drumming career! As the kicker is designed proportionally for each bass drum, the volume of air percentage is consistent for each bass drum.
The Kicker has been designed to project low end bass frequencies clearly, whilst absorbing and eliminating muddy mid and high frequencies, giving you a tight, focussed and powerful kick drum tone.
