Bass port damper 90 mm Dynavoice DAM-90 2 PCS

Bass port dampers made of foam rubber designed to provide more controlled bass reproduction. If you experience slightly overpowering bass in your room, you can try plugging one or more bass ports. Generally, this results in a slight loss of bass energy, but what you gain is enhanced control. To ensure compatibility with your speakers, you can measure the diameter of the bass port. The port should be a few millimeters smaller for a secure fit.
