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.

Really Enhanced the Sound from my speakers

Written By MJAinKY, Kentucky on Saturday, September 19, 2015

Crutchfield Customer Review (What's this?)

I ordered these baffles along with the replacement speakers for the rear doors in my 1999 Subaru Forester. They were easy to adjust to my exact needs and really made a difference in the sound quality. For the price, they are a steal.

Pros: Easy to alter for exact installation. Enhances sound quality.

Cons: Can't find any CONS.

great suggested add-on

Pros: fit perfect

require trimming as expected

Written By Bobco, Mauldin, SC on Saturday, October 25, 2014

Crutchfield Customer Review (What's this?)

Trimmed to fit cut small slot at curve, cut slit access for speaker. Leads. Fit was tight on forward speakers as stock grills we're tight but managable.

Pros: Keeps speakers from druming sheetmetal

Cons: Would be difficult to install for mechanically chalanged

Could be easier to install

Written By Terry, Cedar Rapids, IA on Tuesday, October 21, 2014

Crutchfield Customer Review (What's this?)

The density & general construction of these baffles is good, but I found them too deep for my installation. Rather than send them back I just removed about a inch from the middle and glued them back together. Thereon the installation was relatively easy.

Pros: A must for door installations.

Cons: Required alteration.

Crutchfield Customer Review (What's this?)

Installed these with my Kicker speakers and they fit perfectly.

good ideal

Written By jl, Shreveport, LA on Thursday, February 20, 2014

Crutchfield Customer Review (What's this?)

Good idea for small speakers in doors. Installed these with a pair of kicker 4" coaxils. The difference these things make for sound of the speaker is night and day.

Pros: Slightly increases lower-mid range bass response. Nothing major but it is a help.

Cons: Can't think of a single con.

They seem to work great. They were super easy to install in the factory brackets.

Pros: Super easy to deal with.

Cons: none that i can see.

Great product

Written By ThePotts, Maceo, KY on Friday, October 04, 2013

Crutchfield Customer Review (What's this?)

These do what they're supposed to do - contain the sound of my speakers in the door. I admittedly didn't try the speakers first without these baffles, but the cavity inside the door is HUGE. I can only imagine that I'd get some of that hollow, echoing sound we've all heard if I hadn't used these baffles.

Pros: Works great, easy install

Great Product

Written By T H, St Charles, MO on Tuesday, October 01, 2013

Crutchfield Customer Review (What's this?)

These baffles were just what I needed to ensure that my component speakers stay nice and dry. The sound is not effected if you cut a small hole in the bottom to allow your speakers to do their thing.

Pros: Inexpensive way to protect your investment

Cons: None

Worth it

Written By Nick, Anchorage Alaska on Wednesday, September 25, 2013

If you get the speaks spend a couple extra dollars on these for better sound quality. Other wise the door panel rattles

Cons: Have to modify

Baffles are a huge improvement in over all quality and feel there is value in purchasing these with speakers.

Pros: I highly recommend them.

great product!

Written By Alex, cerritos, ca on Tuesday, May 28, 2013

Crutchfield Customer Review (What's this?)

I have been using baffles for a long time now and I am never disappointed. I strongly recommend them if you are installing from speakers free air. These baffles will not only protect them but also clean up that hollow in the air sound commonly found in most free air installed speakers.

Pros: good price and fast shipping from Crutchfield as always. Product works!

Cons: none yet !

These are a MUST!

Pros: Adds sound performance! Aids in speaker protection!

Cons: None!

Just what I was looking for

Written By Stormy, Twin Cities, MN on Thursday, March 15, 2012

Crutchfield Customer Review (What's this?)

I purchased these speakers to replace the 18 year old blown out factory speakers in my Geo Metro. I have a 50 mile per day commute and wanted to hear my music without all of the ferocious distortion. I don't listen to the radio very loud, so these work just fine. In my noisy car the comfortable listening volume is 16 - 20; these speaker don't start to distort until around 30. I'm well please with the speakers the price and especially Crutchfield for making everything so easy.

Pros: price, sound quality at low to mid volume

Cons: not a lot of range, base isn't great, distorts at high volume.

First time

Choose wisely, doesn't help everybody!

Written By pdok, Oklahoma on Monday, December 28, 2009

Crutchfield Customer Review (What's this?)

Toyota Corolla - Door speakers and rear hatchback speakers. 4" and 5" sizes.

These were pointless for my car. I compared the sound with and without them,
and I absolutely preferred them without the baffles. The back speakers actually
sit in a tuned port enclosure, so I lost that effect by installing these (I was
unaware of the enclosure until I took off the covers.)

The front door speakers are smaller, and having the baffle installed killed off
some of the depth of the bass coming from the space behind the door panel. Say
what you want about the sound "quality", tightness, etc., but without any other
speakers up front, the low-end sound seemed to just go away when I had the
baffles installed.

This might be fine if you have other speakers filling in those gaps in sound,
but for me, these things ended up in the trash can.

I'm not saying they don't work, but just not for me and 15-year old Corolla.

Nice and thick

XTC 4" Speaker Baffles

Written By jason, Newport Beach, CA on Thursday, February 26, 2009

Crutchfield Customer Review (What's this?)

Definately improved sound quality and eliminated the rattle in the dash but
the amount of torque required to hold down the speaker is enough to tear
a hole while mounting.

A change from thin to bodacious!

Written By rulisg, Costa Rica on Thursday, March 29, 2007

Crutchfield Customer Review (What's this?)

This ones DO change the way speakers sound...
Prior to the installation, the sound was OK but lacked some body; after these were installed, the sound gained a lot of consistency, similar as if the loudness control of your receiver has been just activated.
They don´t add any bass at all, sorry, but that character is part of the speaker desing per se instead of any accesory you may add.

Good protection, bad sound!

Written By Kahres05, Fleetwood, PA on Monday, March 12, 2007

Crutchfield Customer Review (What's this?)

I bought these for my install for a 2005 wrx. The speakers are polk db400's. First off, I made the mistake of not testing the sound of the speakers without the baffles. Anyway, the system sounded good with the baffles in but I have a sub in the car so I didnt realize how much bass I was loosing. So I turned off the subwoofer and found out the speakers had like no midbass, I was dissapointed and not pleased after that. They say these baffles improve bass response not kill it! Knowing these are great speakers from a previous install I knew it had to be the baffles. I called Polk support to find out what they thought about the baffles and the tech said that would completely kill the sound of the driver. So I took my door cards off, pulled the speakers out and cut the baffle backs in half so air flow was good, but still had protection from water coming off the windows above; looks like a speaker hood. The end result was nothing but great sound with some protection but the audio was the way it was intended for. I only recommend this product if you properly vent the rear of the driver othervise dont be talked into buying these.

XTC 4" Speaker Baffles

Written By Kenneth, Skamokawa, WA on Friday, September 02, 2005

Crutchfield Customer Review (What's this?)

These are a "must have," especially if you have small speakers. Even with bass blockers, which helped a little, installed on my 4 inch Pioneer TS-G1040Rs, they still bottomed out during sudden bass thumps. Having these baffles behind each one seals up the rearends so the woofer cone has a bit of cushion. They sound WAY better now!
