Design EngineeringDEI 050331 Boom Mat Speaker Baffles, 6.5" Round Slim (Pack of 2)

These were a great price, and I really like the way that they seal off and protect the speakers on my old muscle car. They probably sound a little better too.

Foam baffle worked as it should making the sound quality on my 4runner more strong!!

I recently put these in the driver/passenger side doors of my 2000 subaru rs sedan with 6.5 in Polk dxi650 speakers. My main reason for getting these was because when I installed my door speakers it was snowing out and I noticed water dripping directly onto the speakers. So, I rigged a thick plastic sheet into the speaker hole on both sides, placing the speaker and wires in the created cavity and leaving enough plastic on the edges so when I bolted the bracket back on it would create a seal so no water could get in.This did work but, my speakers couldnt breath. Now these arent very bass heavy speakers but making it so NO air could flow from behind the speaker made the plastic bag cave I made for the wires/speakers breath inward and rattle like crazy causing a super annoying sound on top of my already rattling door panels. So I needed a fix and thats what these baffles are for.I did have to modify my original brackets though. The brackets come with a sort of half cone protruding from behind creating a half cavity, for depth and to protect the speaker (but this still failed with rain water depending on how your speaker actually fit in the brackets with its terminals). I cut off the half sphere lumps to create a smooth flat bracket, inserted the new foam cave (so it goes foam brackets from speakers->plastic bracket screw into door panel->baffle->speaker) and positioned the speaker so the terminals are on the bottom. Cut out an area I felt wouldnt allow water but air could get in, and mounted.This did meet my requirements for water proofing, rattle reducing and plastic eliminating but there are drawbacks after experiencing the setup for a few weeks. First, while the bass is reduced this makes the rear speaker bass seem much more potentb thus throwing off the entire balance of rear/front. Some music is ok and there isnt much difference but a lot of times Id say my front speakers sound 60% the volume of my rears (adding +1 to my front with the front/rear balance of the head unit causes such a great difference in power output it makes the rears sound invisible). The baffles will also redirect the sound output to directly forward. To alleviate this cut more foam off the back of the baffle. I couldnt because of the rain issue which in this case causes the music to shoot at my feet instead of giving the "atmospheric" effect. Its not nearly as bad if you drive alone but when someone is in my passenger seat I can barely hear the front speakers unless the song is heavy on treble.All in all a good product for what I needed without fixing my window seals, buying dynomat and spending tons more money. My fix for the difference in sound dynamics was to buy an app called TuneShell for my iPod touch so I could better tune the music equalizer and take away the bass more subtly and raise the treble than what my head unit allowed.If your car has leaky windows, if you need to direct the sound output directly forward, cut out bass for an amp, etc, buy these. They are cheap and will hold you over until you can plan accordingly.

Fit perfectly. Easy to install and customize to size. I never installed speakers in a vehicle before, this my first time and this item was extremely easy to use. Would recommend

The product was easy to install and was a good price. It amplified the sound and also helped to keep the speaker protected from anything that gets into the door. It made my speakers sound better and louder.

These do change the sound of the speakers in your car however I cannot say they make it better. It may be a personal preference on if you really need these but if its the sound you're going for, I am glad they exist. They are lightweight and easy to install. They are sized for six by nines or eights and are a soft foam essentially. They are a good deal considering the cheap price

The sound difference in control of the woofer or the mid-range is unbelievable the difference it makes. Night and day.

Wanted to add more sound deadening when upgrading my speakers and these made the most sense compared to sticking foam sheets on the inside of my car doors. Also provide water protection should rainwater drip inside my door.
