Design Engineering 050330 Boom Mat Speaker Baffles, 6.5" Round (Pack of 2), Black

V. Good.

Installed these as part of an overall upgrade to my TJ 99 sound bar, worked well to reduce the vibrations in the sound bar and provide more depth to the sound and improve the overall sound

I’ve seen where people say they loose bass or is doesn’t help, those people are wrong. I’ve used these for a long time. It reduces the “loudspeaker” crackle and helps your speakers by adding back pressure and you ultimately get your Bose audio sound out of your pioneer speakers. Don’t think about it just buy it and thank me later. Plus they protect your speakers from water that gets into your door and ultimately in the speaker and causes them to fall apart, ever notice how certain cars the door speakers sound like they are flying apart when your turn the radio up? Cause they are paper cone speakers with no insulation to prevent them getting wet as they age and the glue pulls from the cone or the cone falls apart. These prevent that and protect your investment. Just make sure you run your wire in from the bottom not the side or top.

Se lo coló que a mi cheyenne para evitar que se le meta el agua a las bocinas, cumple muy bien!

Works great

These have improved the sound quality of my car speakers noticeably, as the car only has a single door speaker each side it's well worth the cost of the product and time to install.They also have the added benefit of protecting the speaker connector from any rainwater that may get inside the gap between the window and door (is an old car, so this gap is more significant than a newer car)Importantly, you must cut a small section out of the bottom of the rounded part, to allow for the movement of air, if you don't do this, you will muffle the speakers, not improve them.

Works as a barrier to prevent water leakage on speakers. But nothing there to increase sound quality. Not recommended if your looking for sound dampening or enhancing sq. But works well for protecting speakers against moisture.
