The first product of our new powered subwoofer line features a cast frame 10" woofer with a special Kevlar cone. We made it wide instead of tall so it would easily fit under your mixing console. The built-in active crossover is designed for both LCR and 5.1 systems. Look inside and you'll see our usual attention to detail; the S10 has both vertical and horizontal internal braces, and even the ports are covered with sound deadening material. These details add up to make the S10 the best sounding active subwoofer in its price range.
