I agree with what most others have said about this product - it significantly cuts
the bass. Maybe if I had a subwoofer it would be fine, but I don't and even cutting
a large port hole as described in other reviews cut the bass too much for me.
However, I still wanted some protection because when I installed them there
was still a lot of moisture within the door from a recent rain and there was a lot of
corrosion on one of my pairs of speakers (4 years old) So after several days, I
removed the baffles and cut them so only the top half of the shell was left to form
a protective hood over the speaker. It sounded much better after that and I think
that I have enough protection from dripping water.

Worked great with my new speakers installed in my 2000 Ford Ranger truck.

I purchased a set of these when I ordered a set of the Polk Audio db571 speakers. I have them installed in a 97 Ford Ranger pickup in the front doors along with a Kenwood HU. Like some of the reviews here I cut a hole in the back about the size of a fifty-cent piece to act as a port as I thought the baffle muffled the sound without the hole, plus it made a nice spot to run the wires out of. I actually tried my new speakers without the baffles, and then with the baffles, and again with the baffles and the hole cut out of them. In my opinion they made a huge improvement in bass response. I would highly recommend using them and doing some experimentation.

I always like to leave a comment about Crutchfield any time I leave a review and this is no different. I would like to thank Bill Crutchfield for putting together a very customer friendly customer service department, your people are the best, period! I have been treated with nothing but courtesy and professionalism when ever I have called or emailed. I don't mean to go on and on but in this day where customer service is a "lost art" it's really nice to know there's a company out there that still delivers and I would say this is 75% of the reason I purchase from Crutchfield. Plus their products are priced in everyone's range and selection is incredible. Great job!

Of course theres some custom fitment issues i ran into, but nothing i couldn't handle.
These really do make them cheap speakers sound like $200 speakers. Highly recommend.

It is nice to know that my new JL 5x7's are protected from the elements. Nice product.

I purchased four of these to help protect my new Infinity Reference speakers I installed in my 94 Cougar. I read some reviews here that said that these will kill the bass coming the speakers, but I really disagree. I tried the speakers both with and without the baffles, and found that the sound is better with them in there.

I will admit that I am not an audiophile by any stretch, but for what I have installed (a JVC head unit and Infinity Reference speakers) in all the stock locations these worked out really well, are easy to trim and if you hate them, they will come right out.

For those who purchase these baffles thinking they were going to make some sort of huge difference in your sound, go back and do a little more research. These things basically do 2 things very well, depending on your enclosures they will effect the bass sounds coming from your speakers. In my ford pickup when I opened up the doors and rear panels I saw raw metal all around the speaker locations. I'm thinking Gee.... metal doesn't really make a good speaker box! So after I placed these baffles in the speaker openings they immeadatly started to reduce the hard refllective sound and - yes - increased my low frequencies sounds quite noticeably! Secondly, should water or ice or dust and 'whatever else' get in there, the speakers are protected. End of story! And for the few bucks they cost I'm thinking it was well worth it and in-fact I'm getting a second pair for the rear speakers too now that I've seen the metal inside my 2006 Ford ranger.

The description said they would work for either 5 x 7 or 6 x 9. They are a little skimpy for a 6 x 9 . Since I was stappling them down to a shroud,I was able to stretch them to make them fit, otherwise they would never have worked for a 6 x 9.

I put these behind a set of Boston Acoustic SL80 speakers. They sounded more natural than without. I am using 300 hz bass blockers so maximum bass was not my goal. That is what mid bass and subwoofers are for. If you don't care about water protection and want to weigh your car down with Dynamat then you probably don't need these.

Baffles perform as they should-protect the speakers from the elements. There may or may not be any enhancement to the bass emanating from the speakers. Bass enhancement is not the intended purpose of implementing the use of a baffle.
