Dynamat vs Fatmat

I am getting closer to my 12B overhaul and found an alternative product to Dynamat called fatmat . I wanted to know if anyone has had any experience with this product. is is far less expensive than Dynamat, and since in this particular application, we are only looking to stop vibration, not block noise (which is what Dynamat is also designed to do), this should work fine. Actually, Felt or even silicone caulk would probably work to stop the speaker basket from vibrating, although caulk would be a mess to apply.

Please let me know if you have had any experience with this product.

    I've used both and I can't tell that there's any difference when damping speaker baskets. They look very similar, too.

    Thanks. I assumed that was the case - and I can get 10 sq ft for $20 shipped. That is far less than Dynamat!

    We are looking to stop/block both as one is the same as the other. Dynamat Extreme appears to be thicker and therefore will do a better job.

    I just used a dynamat wedge kit. It is like a 4 foot roll and it was enough to do my RTI A7's and CSI A4.

    Your talking about putting it on the magnet shields and basket fingers right?

    $24.50

    I am just giving another option from my car audio days. One of the best rated products that I used was http://www.raamaudio.com/. Another alternative would be http://secondskinaudio.com/

    Evening Michael,

    to add to the mix, I have fat matted all my polks and it worked wonders from the moment I applied it.

    I think you could get away perfectly with the fat mat and save yourself some $$ for later overhauls.

    My 2 cents for ya, make sure to spend them wisely, we are in a recession.:lol:

    Yes, this is to dampen vibration on the speaker baskets (magnet shields and fingers). Everyone that has done this said it made a tremendous difference. I happened across the FatMat product and thought it would do the same job for a lot less.

    Very similar, but cheaper. Either will do the job, but if you can save some coin, I would (and have) gone that route.
