The Sundown Audio M15D2 from the M Series delivers extreme low frequency performance with massive excursion and low distortion, all at an exceptional value. Built on Sundowns patented Mega platform cast aluminum frame and featuring the signature Mega Roll surround, this 15 inch subwoofer is engineered for powerful output in ported enclosures while maintaining excellent sound quality and durability.

The M Series incorporates Sundowns proprietary PG linear suspension and an internal aluminum shorting ring to reduce inductive distortion and improve clarity.
