Our take on the Boom Mat 6-1/2" 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. Call one of our Advisors if you have questions — they'll be happy to share their expertise with you.

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.

Our 2008 Chevy Silverado speakers shorted out. Water is known to seep by the windows and short out the speakers. According to others online the baffles will prevent future water damage known to occur on 2007-2012 Silverados. [ Gregory  May 21, 2016 ]

The main reason for ordering these baffle is for added protection from water damage which seems to be a big problem with Silverados. [ JIM  Apr 02, 2016 ]
keep water from dripping onto my speakers. The window's often leak water down into the door, and enough water will eventually damage the speakers. Since I'm in there replacing the crappy factory speakers, I might as well take the extra effort to protect the new speakers. [ STEPHEN  Mar 30, 2016 ]

tighten up the sound with the baffle, instead of giant open trk. door. Plus it is water resistant and my door is leaky. Sounds much better and I feel more comfortable. [ jason  Mar 08, 2016 ]
Weather protection and sound improvement. [ Daniel  Feb 25, 2016 ]
I will need to cut out the back of the existing baffle due to clearance issue with the speaker depth. I will need something to protect the speaker back from the elements. In addition, it will help to improve the sound somewhat. [ rickland  Feb 23, 2016 ]

Prior experience [ Steven  Jan 31, 2016 ]
I know very little about car audio. I hope the purchase is worthwhile. I picked these baffles for three reasons. First, I wanted some type of gasket between the speaker and door panel to reduce vibration. Second, I wanted to protect the speakers. I just purchased a used car and all four of the main speakers were damaged. Third, I have heard of this brand and seen it in stores (not really a well informed decision, but...) [ Mike  Jan 12, 2016 ]
These things just make sense: most people wouldn't think of installing a sub woofer without an enclosure - they just don't work right without them. So why not "enclose" your smaller speakers as well? So maybe they are not as 'tight' as a sub box, they will still improve your base response, dampen any rattles you may get from a dash or door mount, and help protect your vulnerable backside - of your speaker, of course. [ Danen  Jan 01, 2016 ]
i like big bass and i can not lie [ denis  Dec 31, 2015 ]

To protect the speaker and improve bass response [ Paul  Dec 12, 2015 ]
I believe that they cut down on vibrations and you lose less sound in the door.Plus they protect your speakers from moisture. [ Theresa  Dec 06, 2015 ]

Because my speakers sound like crap [ Richard  Feb 28, 2017 ]
Reviews say they protect speakers from weather, that might leak into doors. Cost was reasonable so I went with the added protection. [ Auther  Jan 18, 2017 ]
2007 Honda Civic Factory Front Speakers are inoperative. A little research online led me to a common issue with these vehicles. Water from rain and carwashes runs down the window, inside the door and drips on the speakers. The speakers fail over time. Zero sound coming from the front. I chose these baffles to protect the replacement speakers I ordered. I expect them to attenuate some of the bass response, but want a lasting fix. May cut out the bottom to help with sound. [ TIMOTHY  Jan 10, 2017 ]
They add clarity to the sound. [ Robert  Jan 07, 2017 ]

bought these as extra security for possible water intrusion in my Sierra doors [ John  Nov 25, 2016 ]
Because the doors are exposed to moisture and dirt. The 2-1/2 depth baffles were chosen because they will not hit the window regulator. [ Tony  Nov 20, 2016 ]
Had to clean up unwanted vibrations from the Jeep overhead sound bar. [ Mark  Nov 19, 2016 ]
The 6.5" Alpine speakers I originally installed in my vehicle in 1995 have deteriorated and the woofer cones are disintegrating. I think this is partly due to the 1967 automobile door design, which basically allows water to flow down inside the door, directly onto my speakers. My hope is that these baffles will prevent this water damage. [ Wayne  Nov 16, 2016 ]
Protect speaker, hopefully reduce vibrations on door panel. [ Michael  Nov 04, 2016 ]
these help make a good seal around the speaker. keeping moisture and dirt out along with providing a little bit of sound deadening. [ MIKE  Oct 09, 2016 ]
The entire system is based on the recommendation of Jane. I felt I could trust her judgement and did so. Because I may replace the truck soon she did not try to sell me up and gave me what I needed. I even offered her a job in CA!! [ David  Oct 06, 2016 ]

I chose this product due to the age of my vehicle and the proximity of the speaker to the window glass. I feel that protecting the speaker from additional moisture is important even when the speakers are rated for marine applications. To me that does not include the wiring segments and are thus prone to corrosion. [ Joshua  May 31, 2016 ]

These are to protect new door mounted speakers in a 1975 Chevy Truck. The interior of the doors are exposed to outside moisture and although the speaker cones are made of polypropylene, these baffles will add another layer of protection from the elements. [ MICHAEL  Mar 13, 2016 ]

To get better sound from speaker and protect the speaker from moisture. [ Gabriel  Dec 30, 2015 ]
It's important to create an airtight space for your speakers to sound the way they were engineered to. By placing these baffles behind your speakers you are enabling them to perform to their highest specifications. [ James  Dec 28, 2015 ]
Wanted to get better sound quality and after reading the reviews I knew it would be a good choice. Was going to install Dynamat behind the speakers but found these instead. Were recommended so anything is better than nothing! [ Joshua  Dec 17, 2015 ]

3 questions already asked

I used this product when I installed new speakers in my old truck and it seemed to make a noticeable difference. Can't really address how they might affect ceiling speakers, but I was satisfied with them in my application. [ Stewart  Aug 03, 2016 ]
For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Sep 08, 2015 ]  Staff
I would think you need to cut a hole in it either way, cause you have to get the wires through. I just cut about an 1" slit in the bottom of mines. [ Victor  Mar 28, 2015 ]
Its probably up to your tastes. I initially cut the bottoms out and installed them. I found the sound muffled and the volume reduced too much. I then cut out part of the sides and the sound improved so I left them in. [ MIKE  Mar 28, 2015 ]
As I recall (been a few years), I poked a hole through just to feed wires. What I can tell you is that these definitely improve sound and amazingly keep sound focused within the cabin as opposed to making the door pocket resonate and buzz. I always think people next to me are annoyed by the loud music, but when I get out and close the door, it's not loud outside at all. (I do have insulation panels) [ GEORGE  Mar 27, 2015 ]
Do you want to use the door cavity as the "cabinet" for your speaker or a little tiny cover? The cover without a hole will turn a very small volume into a sealed speaker cabinet, which will limit bass response.probably not the best choice. [ AARON  Mar 27, 2015 ]
