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 fo r. 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.
