This Listings Includes:

• (1) Sundown Audio Series M Subwoofer 15 inch, 2000 Watts RMS, 1-Ohm

The Sundown Audio M15D1 from the M Series delivers extreme low frequency performance with massive excursion and low distortion, all at an exceptional value. Built on Sundown’s 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.

At the core of the M15D1 is a quad stack 200mm motor structure paired with a 3 inch 4 layer aluminum voice coil wound on a thick aluminum former. This advanced coil design allows an impressive 35mm one way linear excursion while maintaining thermal stability during high power operation.

The M Series incorporates Sundown’s proprietary PG linear suspension and an internal aluminum shorting ring to reduce inductive distortion and improve clarity. Combined with high velocity pole venting, backplate gap venting, and frame integrated cooling, the M15D1 maintains consistent performance even under demanding bass conditions.

Designed for serious bass enthusiasts who want deep extension, strong output, and reliability, the Sundown M15D1 continues the Mega series tradition of delivering extreme performance per dollar.
