The KickPort 2 Bass Drum Sound Hole is an innovative bass drum accessory which can be attached to the resonant head of your bass drum to deliver enhanced bass response. The device can be used on any bass drum and any head material. The KickPort focuses the air as it leaves the bass drum, resulting in a natural compression which increases punch and adds to the overall depth of the sound. When paired with a high-quality bass drum and drumheads and with a little bit of tuning, the KickPort 2 Bass Drum Sound Hole can transform the sound of your kick, making it an essential for any drummer, whatever their chosen style or genre.
