Best to cut out undeside in doors to allow for better soy nd

I cut the bottom off of these baffles and I am using them with the 6x8 to 5 1/4 speaker adaptor plate. Prevents my speakers from rattling when my music is turned up. Easy to cut.

Great product! Used them on my Boston acoustic dash speaker. After cutting out the bottom and installing it improve sound quality greatly

Great product it shipped same day, makes speakers sound better and prevents them from rattling. I recommend everyone to purchase these if installing speakers. Front or rear door.

these work great with my new pioneer speakers makes the bass hit harder and makes the speakers sound so much better

Purchased these to help reduce the road noise on my 5 1/4 aftermarket speakers in my F150. Installation took about 5 minutes for both front door speakers and they do their job just fine - reducing the road noise.

I just purchased Sound Ordinance 5-1/4" and 5" x 7" speakers for my 95 Dodge Dakota and was recommended by Crutchfield to buy the baffles for at least the front to help keep moisture out. I bought baffles for front and rear and installed the rear first. It's a little difficult to install the speakers into the baffles and then into the speaker mount while contending with the speaker wires but not to bad. I tested the sound of just the rear and it sounded really good so I went on to the front. Thats when I started have issues with the front 5-1/4" speakers and baffles. The speakers mounted loosely in the baffles where the speakers were not very snug in the baffle and had just a small cap between the magnet and the back of the baffle. I installed anyway's and tested the sound. It sounded horrible. There was a severe rattle or distortion in the doors & looked like the speakers were struggling to function especially with the bass. I got my hand behind the speaker and lightly pressed against the baffle so that it was touching the magnet; the rattle sound went away! The back of the baffle was vibrating against the speaker badly. So I tried cutting some ports on the side of baffle to free the air but didn't eliminate all the vibration. I then cut almost the entire back of the baffle out & the vibrations completely stopped & sounded great. I'm really baffled about the baffles. Why they work great for rear & not front is unknown.So I guess don't buy for smaller speakers!

still not convinced on this product i think it hampers bass even with hole cut in rear

Good to use if you can. Helps shallow speakers to sound better.

I bought the 5.25 inch size and it was not more than 1/8 inch larger than the speaker magnet. Putting a woofer in an extremely small cabinet damps out the motion of the cone and prevents it from vibrating below a certain frequency. I tested these in my shop with soundeasy digital testing system and calibrated microphone accurate + or - half dB from 20hz to 20k hz. The driver I tested was an audiophile driver with an FS of 50 hz and measured response to 40 hz in my car. With the baffle.. in my shop, response stopped at 300hz and dropped like a rock below that at 18 dB per octave... so no usable output at all below 300hz. It would be great to use on your rear door speakers... even better than bass blockers.. but if you want anything lower than midrange, you do not want these.

First time purchasing the baffles no problems or complaints.

Made the sound in the front 2 doors allot btter. Good add on by the Crutchfeid rep.

I installed these front and rear in my 05 silverado ext. cab. The rear factory speakers
were pretty dirty when i took them out so i think they will help protect the new speakers
there, the front door speakers were pretty clean, but I do think they will help with noise
and vibration as well. I played the new speakers with and without the baffles and they
seem to sound sllightly better with the baffles.

Installed these baffles because Crutfield rep said they would help with bass response. Wow where they wrong it decreased bass response by 75%. So i tried it without the baffles and wow just one speaker sounded better than both (in phase) with the baffles. So removed both baffles now everything sounds awesome. Don't wast your money.

As an audio engineer, system designer and installer for 21 years, you cannot shove any speaker in any opening with any amp and expect it to work.

If you have learned about crossovers, frequencies and slopes, as well as the impedance of the speakers to match them with the amp, then go one step further and learn about Thiele/Small numbers. The lower the frequency to be produced, the more air space required to produce it. In small spaces, this can be manipulated with vented boxes and port design, but if you install these baffles behind a full range speaker, you are losing the open air space of the door or rear quarter panel, and therefore lowering the ability to produce lower frequencies.

These are great products when used as part of a whole system design.

They will clean up the lower mids, reduce unwanted vibrations, focus the higher mids and protect your speakers.

Do not use them if you do not have a component system with separate subs and still expect decent low end.

As many have reported, installing these baffles with my new speakers wiped out the bass. I wish Crutchfield Tech Support would have read these reviews and helped me figure out what had gone wrong. It took returns, new and different speakers, many hours and much frustration to figure out it was just these simple pieces of foam. If your speakers need protection in the back, fix the door. Don't sacrifice sound quality for protection.

im shocked in that everyone in this review page is bashing a wonderful product. let me ask a question did anyone lower there x-over freq to allow for the baffles? my bet is no.
its not taking anything away but "controling" the speaker, meaning if your still using the setting as you did when they were free air, your way off.

Installed these in my doors and they rub on my windows even after i put a spacer in
there. They still make my cheap speakers sound good.

So I first installed my speakers without these baffles. I have four 51/4" kickers. I isolated each speaker and listened to it with and without the baffle. I lost a lot of bass with the baffle the s[eakers began distorting much sooner. Unfortunately my door seals leak, so I need them. I just got a sub and some bass blockers to fix the bass problem.

Even with my factory speakers, my truck had that infamous rattling noise when the volume was turned all the way up. These baffles will not get rid of all the vibrations, but do make a big difference. They also protect your speakers from the elements, so including these in your installation is a good idea.
