These definitely allow the speakers I installed these behind to sound their best. They also allowed me to mount my 6x9's in a hole that wasn't a perfect fit for the basket, and not rattle or vibrate excessively.
These are good quality foam, as good as the other brand of baffles for sale on Sonic. Like me you may have to cut out the bottom of these to let your speakers breathe. I needed these for use as rain guards in my doors. I live about 50 miles from Sonic's Louisville, KY warehouse, so when I order from them I usually get my package the next day!
Geat value and protection.
Excellent fitment. Easy to install. Keeps moisture away from speakers. Great for marine speaker installations as well.
These made my polk audio 6x9s very quiet and distorted. I had to cut holes in them to get a clear sound out of them so they dont work as well as i thought
Makes the sound come out not stay in the door or not go back in the trunk
