21 of the Top Subwoofers for a Thumping Home Theater Sound System
RBH Sound SI-1010
Utah-based RBH Sound developed the SI-1010 to install into ceilings or in the floor of a home. The sub uses a pair of non-powered 10-inch aluminum cone woofers, and it is powered by the outboard SA-500DSP amplifier. The SA-500DSP incorporates smart circuitry to prevent the sub from being overdriven, and once installed it looks like a common heating vent.
