Smart Dc Audio M4 8 | 8" 800 Watt Car Subwoofer Tool [1htEJkXd]

The m4 8 is an 8" long X-Max subwoofer. We have been asked for a 8 that smashs 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.
