DS18 DSFR6 6.5" Car Door Foam Speaker Rings Blocker Soundproof Sponge Speaker Baffle Fast Rings Stereo Foam - Espuma Para Altavoz (Sold in Pair)

These are awesome foam speaker surrounds. Very good quality foam and adhesive. Perfect fit. No issues with these sticking and staying in place. Don't install new speakers without these and enough stick on sound dampening mat to cover at least 20 percent of your metal door panel to eliminate vibration. A little bit of extra time and money makes a big difference in sound quality. Be sure to install some sound deadening on the outer door skin through the speaker hole as wel. I chose this kit because it uses open cell foam for the baffle which absorbs reverb better than closed cell foam. Open cell may not be the best choice if you get a lot of water inside your door however, since it absorbs water.This kit worked great. No unwanted resonance and sound is directed into interior cabin. My vintage MB Quarts are rocking again and sound amazing.

Very high quality and really do help keep the sound in, the adhesive is really sticky I highly recommend

Mounted the speaker in a speaker box, and it works so perfectly. Great bass

Easy to install & sound good

Nice and good feel/fit3m adhesives are a huge plusGood price

These worked perfectly for installing my new speakers. Did adhesive was strong, and these were easy to apply to my new speakers. They definitely make a difference.

They fit perfect

Absolute junk. There is no adhesive at all on these rings.
