10 Inch Subwoofer
This Sumiko S.9 subwoofer is a bit of an anomaly in the field of subwoofers. It uses a 10 inch downward facing driver coupled with a 10 inch front firing passive radiator. The uncommon trait here is that it uses a 350-watt RMS Class AB amplifier. In a time where most sub amps are class D, this is a big deal. Like most Rel subs, this Sumiko also uses a Neutrik speakON connector to provide speaker-level input. By providing input through your amplifier or receiver, the entire system, including the subwoofer, is coherent and consistent. Highly recommended.
