Introducing the SML series: a revolutionary line of subwoofers by Sundown Audio. This series is an inch shallower than the SLD line, yet delivers nearly the same excursion, making it the ultimate choice for customers in search of an extremely shallow driver with deep bass. Specifically designed to fit under or behind your seat, the SML series excels in performance, especially within small enclosures.
