Our take on the Boom Mat 6"x9" Speaker Baffles

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.

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.

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.

Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I've heard they work well for motorcycles, so I want to try for myself. [ Anthony  May 21, 2017 ]
For quality sound [ Horacio  Nov 16, 2016 ]
Crutchfield made it easy to choose a set of speakers that work with my car. I've done business with them since the 1980s and have always been satisfied with my purchases. [ David  Sep 23, 2016 ]
To cover speakers installed in a boat engine room. [ CALVIN A  Jun 07, 2016 ]
Sound much better and isolates sound waves [ JEFFREY  Mar 02, 2016 ]
the only place to mount speakers in my 89 Ford van is the doors unless using a box type enclosure. Speakers being 3 inches deep and doors being only 4 inches I need shallow baffles. [ Collin  Apr 27, 2017 ]
Basically using these for a speaker box where there is no space for a box. ??? Try anything once! [ Glenn  Apr 02, 2017 ]
I chose these to help produce a more full sound. The factory 6x9 speakers located in the back deck have a lot of air space and we need to fabricate brackets so to help with separation from front of speaker to rear of speaker is a must. These will help with that as well as create an enclosure and help with noise vibrations. [ Edward  Mar 30, 2017 ]
Helps keep moisture and dust out. provides a good seal for speaker. [ MIKE  Oct 09, 2016 ]
I have some 6x9's that I am installing in my son's dodge truck [ Thomas  Sep 30, 2016 ]
Love these Boom Mats ordered a set for my front door speakers 6.5 slim they work beautiful completely protect the speakers and keeps from sounding tinny just ordered a set for my back 6x9 wish I had ordered them with the other one, but I never had them before wasn't sure about the quality, they are nice will recommend for now on. [ Michael  Aug 07, 2016 ]
I purchased the boom mats to help protect the new speakers I purchased from dirt, debris and moisture and I wanted them to help with the sound quality of the new speakers and their ability to direct the sound and bass notes. [ Michael  Jun 24, 2016 ]
These guys always make a great product that actually does what it is supposed to do, eliminate unwanted noise. [ Douglas  May 05, 2016 ]
Used baffles on Crutchfield-bought speakers in my first car: a 1981 Honda Prelude (miss it, man). They were very effective in producing superior sound, and the baffles protect the speaker backs in the doors. I'm using them now in the trunk since that's too big an air space for the rear deck 6x9s. [ Russell  Apr 19, 2016 ]
The window seals in the front doors of my 2012 Ram Express allow water to pour into my doors. Very poor design by Ram!!! The water intrusion ruined a pair of 200.00 CDT Audio speakers in less than a year. I don't want that to happen again so I am installing these to keep new speakers high and dry. [ Gregory  Mar 22, 2016 ]
Hoping it will push more sound in to the cabin of my truck [ Anthony  Feb 03, 2016 ]

1 question already asked

The baffles will isolate the sound waves from the back of the door panel and thus cut down on vibration, but they are primarily used to improve the sound quality by limiting the reflective / out-of-phase sound waves that sometimes emanate from the back of the speakers into the cabin. All cars are not build equal, so the benefit is on a case by case. [ RANDELL  Mar 03, 2015 ]
I meant to say "I don't know if...". [ Guest  Mar 02, 2015 ]
Hi Jeff. Sorry but I know if these baffles will help lessen your door rattle. I installed these thinking that it would help enhance the bass sound. Unfortunately it did just the opposite. In short, the speaker couldn't breathe, hence the bass output was very weak. The only benefit I realized was that it can protect your door speakers from getting wet if there's a leak in your door. To help make it sound better, I had to cut off the lower half of the baffle so that the speaker can breathe and perform as intended. Opening up the lower half will still protect the speaker from water dripping down on to the speaker. If you have the time, I'd give it a try. [ Guest  Mar 02, 2015 ]
The baffles will help with the rattling but won't remove all of it, and may change your sound quality. [ STEPHEN  Mar 02, 2015 ]
It mite,,,but sounds like u need that mat to go behind yur speakers,,I think baffles is for water proofing. [ GEORGE  Mar 02, 2015 ]
I don't think these would help your problem. I bought these and wish to take them out. Just have to find the time to remove all the door panels. These ruined the bass response to the speakers I put in, the factory was actually better. I would ask other truck owners if they have the same problem. I worked for Dodge and don't ever remember the speakers rattling the doors.. [ Robert  Mar 02, 2015 ]
In my opinion the baffles are only good for protecting the backside of speakers from moisture. They might help a very tiny bit for the rattles, but it sounds like the entire door needs a sheet of dynamat, or each door may have a rod,cable ect. that needs insulated. I would take door panel off to see if that was the case [ DAVID  Mar 02, 2015 ]
