Sundown Audio SA-6.5 SW D4 6.5" 200W Dual 4-Ohm SA Series Subwoofer

The SA-6.5SW was created to achieve extremely high performance at less than 4” of mounting depth (3.8” to be precise). Rest assured that even with the limited depth the SA-6.5SW lives up to the reputation of the SA series! These little guys will take a beating in TINY ported enclosures. Our customers have been in love with the incredible performance per dollar since their launch in 2017.
