They look stupid. I would not wear them. This reminds me of the aluminum foil I got from them one time. My celery covered in tar. Disgusting!

Does the job! Had to cut slits in it for wires but that is to be expected.

Really enjoy this product. It's protects the back of the speaker and improves the sound.

This is going to be a mixed review because I'm not really sure what to say. I installed these on one set of speakers, a cheaper set, and it accentuated the sound. Made it produce better low frequencies, just made the speaker sound like it was worth much more, I was very impressed.
On the other hand. I ALSO installed these on a set of expensive speakers that sounded amazing right off the bat. My mind set was "wow! If these sound baffles could make that cheap speaker sound good, imagine what they will do for these". Yeah well they made them sound worse then the cheap speakers without the baffle. Absolutely no mod or lower range, just straight high frequencies.

This MIGHT have to do with my application though. The cheap speakers were 5.25's located in the kick panel with a very holo area behind it. The expensive high quality speakers are 4 inch speakers in a very small awkwardly shaped area that the seatbelt actually runs through. So like I said. Mixed review, worked very well in one case, worked absolutely terrible in another.
They're cheap enough that I can say just get them if that's your plan. If they don't work out hold onto them because you never know. But don't be surprised if you get opposite results then what you're expecting.
Very interested in how they'll preform when I replace the kick panel speakers to the same brand expensive speakers. Maybe I'll post a comparison video and change up my review.

I expected suppression of vibrations from the speaker inside the door (bounce). The product does not delay any vibrations from the bass, all vibrations are distributed through the door, rattling is heard both with and without it. Removed..
The size is smaller than the 6/9 speakers of the Lexus GS 13-20, you have to pull it onto the body, which is not convenient. The glass also rubs against it when lowered. There are no complaints about the quality of the product or the seller. Sincerely!
