PURE GEWA Drummer Thrones round seat DT-400, adjustable height, double braced, heavy

Designed to protect the ported hole cut into your bass drum head. The Gibraltar 6 Port Hole Protector includes two rings which connect at each side to extend the durability of your bass drum head. The Gibraltar Port Hole Protector can be used on any bass drum providing you can cut a sound hole in the resonant head to deliver an enhanced bass response with a sound that can be tuned to your preference. The Gibraltar Port Hole Protector focuses the air as it leaves the bass drum resulting in a natural compression which increases punch and adds to the overall depth of sound.
