Sundown Audio SW-SML12D4

The SML series is a revolutionary line of subwoofers offered by Sundown Audio. An inch shallower than our SLD series, it delivers nearly the excursion, making it an ideal choice for customers seeking an extremely shallow driver with deep bass. Designed to fit under or behind your seat, the SML series performs exceptionally well in small enclosures.
