They're Good

For the price they are perfect and they really do enhance the sound quality. I like that they have such a deep mounting depth, I can fit almost any type of 4 inch speaker. The bad part it is trying to get the foam to form around the speaker, there is quite a bit of a gap between the edge of the speaker and the inside of the baffle. They are not true 4 inch baffles they seem a little to wide to be. But when they are formed right and cut with scissors to fit, they work really well.

Works Great!!!

I used these as a baffle behind my speakers that were installed on a custom plate in my 1986 Chevy crew cab's 4x10 center dash speaker location. They work great, and to be sure they worked I installed the speakers without them and it sounded okay. When i got these and installed them, it made a big difference. I have used these baffles over the years and have not been disappointed.

great baffles!!

Night and day difference with this size speaker. Improved mid-bass was my goal and this product was key. With all speakers performing best when in an enclosure, I also improved over all clarity from my speakers as well. I would take extra time to measure you install spot and take into consideration the baffles thickness as it is not a cheaply made baffle its actually very durable material! 100%

Did their job

Needed the sound from my speakers to project forward and not lose any of their effectiveness.
They definitely did the job.

Does it's job

Since 4'' usuually don't deliver much bass, these are perfect to keep water and such out of the speaker. Doesn't work well for bass as it seems to choke the speaker ( I also have the 5 1/4 and 61/2 ). Not so expensive either.
