Sundown Audio M-Series 18" Subwoofer 2000W RMS Dual 2-Ohm (SWM18D2)

The Sundown Audio M18 is the 18" model in the M-Series, the entry point to Sundown's Mega platform, rated 2000W RMS with dual 2-ohm voice coils that wire to a 1-ohm or 4-ohm load. Sundown recommends a 7.0 cu ft ported box tuned to 32 Hz, or 5–6 cu ft sealed; it also suits infinite-baffle setups. It fits builds with room for a large enclosure that want low extension from a single driver.
