The M4-8 is an 8" long X-Max subwoofer. 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.
