Original Product Details

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 smash 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

Key Features:

Extremely rigid non-pressed paper cone assembly
High Roll Stitched Multilayered reinforced polymer foam surround
Rigid propylene dust cover with White DC logo
Bolted down & spaced Linear roll spiders
Sewn flat heavy duty tinsel lead wire
Custom Cast aluminum black frame
FEA analyzed and optimized motor assembly – Fully CNC machined
Rubber mounting gasket and custom tooled motor boot.
DVC 2.5” Copper voice coil.
