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 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.

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.

I could tell a difference once these were installed. I have no complaints actually glad I got these. Wasn’t sure I would notice anything but the sound is much more focused into the truck.

Good product, will buy again.

Perfect fit - great sound

These are sized correctly for a 6.5" woofer. Installed correctly the the ring will improve the sound from the front of the speaker, and the disk will reduce sound reflections from the door panel. The material has the same medium density style foam as other acoustic products I have purchase over the years. The adhesive backing is made by 3M, which makes the some of the best adhesives on the market. Compared to other fast rings, the price is reasonable. The product specifications don't list the actual measurements. See the photos uploaded with this review for pictures with a tape measure. Ring thickness is 1". Inner diameter is 5.75" and outer diameter is 7.75" Overall, it's a solid product.

Great product, great sound! I recommend this 100%

Simple to install. Rings fit right around speaker and adhere pretty well. 15 dollars cheaper than name brand, will use again next time i do a vehicle's sound system.
