DC Audio DC-M3 8" 1200 Watt Dual 4 Ohm Voice Coil Subwoofer

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.
