SW1820S

It includes two separately wired 18" long-excursion woofer units with a program capacity of 800 watts each (1,600 watts max. x 2), providing a super-solid bottom end.

Yamaha's Active Servo technology offers the most significant benefits in the bass region, the combination of the SW1820S and Y30 Active Servo Processor achieves outstanding results.

It is equipped with a rugged dark-grey carpet finish that prevents nicks and scratches and a heavy-duty metal grille. For easy handling, a pair of casters are installed on the lower rear edge of the cabinet, and a pair of large handles are recessed into the cabinet's top.
