Our XBAF speaker baffles create a tight and secure seal around your speakers, allowing for optimal sound quality. The egg crate foam at the bottom of the baffle helps create a barrier between the speaker and the metal door itself. The XBAFs are engineered with high-quality silicone which lasts a lifetime. Sometimes, moisture may accumulate in your door panel. Our waterproof silicone baffles will keep your speaker safe and keep their shape, unlike comparable foam baffles. The silicone design also allows for simple customization of the baffle to match the proper mounting depth. These baffles are available in most car speaker sizes including 5.25", 6.5", 6x8", 6x9", and even 8". Our silicone baffle rings are the most simple accessories you can install to make your speakers sound amazing. Mounting Depth: 1-5/8" (Front); Mounting Depth: 2-5/8" (Back)
