Our take on the Boom Mat 6-3/4" Speaker Baffles

by Buck Pomerantz

Boom Mat baffles protect your car's new speakers from moisture and dirt. Mounted behind the speaker, the baffle forms a mounting seal that also improves sound clarity by reducing panel vibration that could transfer to the speaker.

These baffles will protect your speakers. In many applications we recommend that you cut a hole in the bottom of the baffle, or remove the entire bottom of the baffle, to maintain good bass response while still protecting your speaker from dirt and water damage. Call one of our Advisors if you have questions — they'll be happy to share their expertise with you.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Overview: These acoustic baffles are designed to be placed behind car speakers to protect the speaker from moisture and dirt which can damage speaker components. Along with providing a sealed chamber, they also form a mounting seal between the speaker and the mounting surface to eliminate panel to frame resonance. Baffles will improve door acoustics by reducing road noise and vibrations transferred to the back of the speaker cone. The baffles are pliable and can be compressed to fit most applications.

Boom mat seems like a gimmick

Written By Chris, Arkansas on Sunday, July 28, 2013
Crutchfield Customer Review (What's this?)
Probably wasn't needed but used a set to try them out. There was a lot of air space where I used them, so basically used them to reduce it.
Supposed to protect the speakers from the elements
Making holes in them to mount the speakers. Pretty much have to install the speaker twice.

Must have for door speakers

Written By Kestas, Frisco TX on Thursday, April 09, 2009
These are a must have for door speakers. They reduce road noise and give a more consistant base with a much fuller rich sound.

Easy to install

Written By Duncan, Albuquerque,NM on Monday, November 10, 2008
This product is a great way to protect the new speakers in your car door from the weather, as well as providing better sound. It is very easy to put this product behind the speaker just before you install the speaker.
