Features: Our replacement rubber surrounds are your perfect choice for repairing your speakers. Made of high-quality rubber material for durability and high pressure. Whether your speakers are new or old, our surrounds can be trimmed to fit your application. Easy to install, perfect for any average DIYer. Usage: 1. Remove the gasket and rub off the old rubber, apply glue to the cone. 2. Center the surround evenly when placing it on the cone, press the inside of the surround to the cone with your fingers, go around a few times until it sticks. 3.
