The m3 8 is an 8" long X-Max subwoofer. Long hours in the R&D department is what it took to develop the newest version of our 8" subwoofer.
We designed a tall roll stitched surround, oversized spiders, and a tall cast frame that allows for extreme amounts of cone travel. All of these newly designed parts allow for lower frequency reproduction.
The bolted down spaced spider design keeps it all linear. The m3 8 uses a gap cooled design to allow the 2" copper coil to thermally take more power than other 2" coil motors with the traditional pole venting.

First off if you’re looking to buy this sub, it is a great 8 and it sounds good at 600 watts which it’s rated at. Now what I had previously was a sundown sd2 8 which is rated at 300 Watts rms. In my opinion the sundown sounded just as good but not quite as loud. The sundown could take more power, I gave it about 450 Watts without a problem. I tried giving the dc more power than 600 Watts and it did not like it at all. I think one of the coils is burnt. With all that said, if you’re looking for a bad ass 8, I would go with a sundown product. But if you want to try something else, the dc is great just don’t give it any more than 600 Watts.
