Sundown Audio M-18 D2 18"

The Sundown M-Series is an all-new "entry-level" subwoofer in their Mega series. All Mega series subwoofers (10,12,15,18) feature custom tooled and patented frames and Mega-Roll surround. The M-series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion. This is all thanks to the Sundown Mega-Roll surround & proprietary Sundown PG linear suspension (fully computer optimized). As with most subwoofers from Sundown. the M-series features a magnet inner-diameter aluminum shorting ring for superior inductive distortion performance as well. Sundown Audio is quite certain that the M-series will go down in car audio history as one of the best low-distortion subwoofers per-dollar of its time.
