Our take on the XTC 3-1/2" Speaker Baffles

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.

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.

XTC 3-1/2" Speaker Baffles

Anonymous from East Peoria, IL on 6/12/2017

Crutchfield Customer Review (What's this?)

Such a great improvement on the sound for such a small investment. Can definitely tell a difference and would recommend to anyone thinking whether they are worth getting. Of course it still helps to have a nice quality speaker, but just adds that little extra something to make them sound even better.

Very good quality, good thickness. I believe the speakers sound better but it is not easy to judge this. I would use them again

These work as advertised. They were quite a bit thicker than I expected, but that just means that they are better quality than I expected as well.

3.5" speaker baffle

Burkey's 66 from Las Vegas on 4/25/2016

Crutchfield Customer Review (What's this?)

Purchased these for a custom stereo install. Have nit installed this pair yet but have used these in the past. Easy to install and offer protection for your speakers. Best for doors as for water protection. using these in dash as there is no room for anything else to baffle 3.5" speakers.

Pros: Cost ease of use speaker protection

Cons: None so far

Slimline did not clear magnet assembly

Danny from Vancouver, WA on 9/20/2014

Crutchfield Customer Review (What's this?)

I bought these inexpensive baffles with the intention of using them for a rear panel mount install of an older set of Infinity 32cf speakers into a VW Cabriolet. When I ordered, I waffled back and forth between regular and slimline depth, knowing the larger magnet assembly may be a tough fit. Bottom line is- the slimline does not clear the magnet. I would return them, but for $7, I would rather not hassle Crutchfield. (I know they would make it right, but since the margin on these is so slim- I'll pass.) Rating based on product quality.

Pros: Non resonant, water-resistant baffle. High density foam appears durable enough for long term

Cons: Slim line baffle does not fit 3.5" Infinity Kappa.

Shallow foam baffles

jb from 50th State on 9/16/2014

Crutchfield Customer Review (What's this?)

Simple molded foam, flexible baffle.

Pros: Seals the rear of the speaker, flexible and waterproof.

Cons: Wish it had an adhesive mounting surface. Also the circumferance should be a little larger as there is no room for the speaker terminals.

It's OK

Genius from Central Florida on 7/30/2014

Crutchfield Customer Review (What's this?)

So far, there is an improvement in sound quality. It does what it's suppose to do. That is to damping reverberation in the sheet metal. It also prevents sound from moving to unwanted areas and reduces road noise and vibrations that are transferred to the back of the speaker cone.

Pros: An improvement in speaker performance.

Cons: Little or no information on what it actually does and how best to use them.

Simple and Effective

Justin H from Burbank, CA on 6/28/2013

Crutchfield Customer Review (What's this?)

Easy to fit and install. Perfect for my custom mounted center speakers in my dash

Pros: protects the speaker while fitting nice and snug

Cons: could be a tad too deep for shallow mounting spots

XTC 3-1/2" Speaker Baffles - solved my problem

99SAAB9-3 from Evergreen, CO on 3/30/2012

Crutchfield Customer Review (What's this?)

My dashboard speakers were vibrating or were causing vibration in my dash. When I installed new dash speakers I added these baffles. I don't know if it was the new speakers or the baffles, but the problem is gone.




Hands-on research

Product Research


Product 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.
