Subwoofer Description

DC Audio M4 8″ Subwoofer

Available in D2 & D4 Models

800 watts RMS 1600 watts Peak

The m4 8 is an 8″ long X-Max subwoofer. We have been asked for a 8 that smashes the lows and takes power.

This is a 8 that will give those that asked exactly what they are looking for. A tall roll stitched surround, oversized spiders, and a taller cast frame than the m3 . These newly designed parts allow for lower frequency reproduction and higher power handling.

The bolted down spaced spider design keeps it all linear. The m4 8 uses a gap cooled design to allow the 2.5″ voice coil to thermally take more power than the m3
