Sundown Audio M-15 D2

The Sundown M-Series is an all-new "entry-level" subwoofer in Mega series - all Mega series subwoofers (10,12,15,18) feature custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841) and Mega-Roll surround. For the M-series, Sundown mate out Mega series frames to a quad stacked 200mm (7.87”) diameter motor structure with a total magnet stack height of 88mm (3.46”) featuring a hyper-extended pole and extreme clearances (allowing 59.5mm to mechanical bottom effectively making it bottomless - this is 4.68" peak-to-peak). Sundown always do things to the extreme so even "entry" level M-series features a full 20mm thick top-plate to finish the efficient magnetic circuit.
