BRAND: Sumiko

TYPE: Loudspeakers

The S.10 is the flagship of the S Series. It is built for those who require higher power and deeper reach from a subwoofer, but with even greater definition and musicality than our smaller models.




The S.10 is powered by an ultrahigh current 500 watt, Class D amplifier. With a 1-kilowatt peak, the S.10 can deliver striking dynamics with ease. An all-new 12-inch driver has been developed with fiberglass sandwich construction, coupled to a 12-inch passive radiator of identical material. This allows the S.10 to reach the lowest frequencies with transient control that is simply not found elsewhere in passive radiator designs.

The new Sumiko WRX Wireless Receiver is built into S.10, providing the same connectivity as the traditional wired setup.

One or more Sumiko S.10 subwoofers in your system will transform your listening experience into a spectacular, life-like engagement that will keep you in your seat song after song, scene after scene – all at a very reasonable price.
