• (1) Sundown Audio M12D1 12 Inch Subwoofer Dual 1 Ohm

The Sundown Audio M12D1 from the M Series delivers extreme low frequency performance with industry leading excursion and low distortion, all at an exceptional value. Built on Sundown’s patented Mega platform frame and featuring the signature Mega Roll surround, this 12 inch subwoofer is engineered for powerful output in compact ported enclosures while maintaining excellent sound quality.
