Sundown Audio M-15 D2
The Sundown M-Series is an all-new “entry-level” subwoofer in our Mega series – all Mega series subwoofers (10,12,15,18) feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841) and our Mega-Roll surround.When we say “entry-level” this is only by comparison to its big brothers in our own Mega line – X,Z,NS series and higher. The M series was built for intense bass with stellar low-frequency performance at industry-leading levels of low-distortion. It does this while looking amazing – with a new laser-etched back-plate design and special M-series magnet boot design.
