Waterproof foam baffles from XTC fit behind speakers to keep them clean and dry. They compress easily to fit the installation, and form a mounting seal that can reduce panel vibration. Use these speaker baffles along with a Dynamat kit when you install your new speakers, and you'll enjoy improved sound and performance.

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.

I used these for my ceiling speakers to seal up the gaps and install something over my speakers prior to doing "blow in" insulation in my attic

Pros: easy, great product

Cons: a little pricy but high quality

Crutchfield Customer Review (What's this?)

I purchased these baffles to install with the factory sub woofer in my Civic. Using these baffles has improved the bass response from this little sub more than i could have hoped. Its not making pounding bass by no means, but it definitely has some more oomph which helps round out the sound in the car.

Pros: Easy to install. Light and cheap. Able to coat in resin to make it rigid to further improve.

Cons: none. these do exactly what i wanted.

Good product

Very good product. Seems to be thick enough to get the job done but not so thick that it smothers the speaker.

XTC 8" Speaker Baffles

Written By rowells, greenville ms on Tuesday, January 07, 2014

Crutchfield Customer Review (What's this?)

this is good product didnt know they are so big for the 8 inch speakers i guess they are more for woofer type 8 inch speakers and not mid 8 inch even though mines are are big but they still were fine in the end and was just the size i needed everyone thought they were top hats on my back seat before i installed them lol im going to fiberglass them and make them stronger after i put them in because i have major aggressive bass and they need strength so the bass wont get to the speakers and distort them like they are doing

Pros: good product

Cons: kinda big but are used for exactly what its for its a good product

speaker baffles and other purchases

Written By jim, Brandon Ms. on Wednesday, June 19, 2013

Crutchfield Customer Review (What's this?)

I've bought two head units, a set of speakers and the speaker baffles from you. Your website is fine. What impressed me the most is the high level of product knowledge your reps have to include helping with install questions/issues. In my book that's something you can't put a price on and the reason I'll buy and recommend you to people I know.

Pros: Fast/accurate shipping. Good price. Excellent customer service.

Cons: None that I can think of.

  • Two acoustic foam baffles for 8" speakers

Product Research


Overview: Acoustic baffles are designed to mount behind car speakers to protect them from moisture and dirt, which can damage speaker components. Along with protecting the speakers, they also form a seal between the speaker and the mounting surface to seal any air leaks and 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 many applications.

Dimensions: Keep in mind the baffle is foam rubber, it can be stretched or compressed so these dimensions are not rigid:

  • Speaker Size: 8"
  • Required Cutout Diameter: 7-3/8" (into which the baffle is mounted)
  • Speaker Cutout Diameter: 7" (of speaker used in baffle)
  • Maximum Speaker Depth: 6"
  • Baffle Depth: 6-1/4"
  • Thickness: 1/4"
  • Flange Size: 10" x 10"
