DC Audio m4 8”
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 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
