When you want to experience more from your movies and music, the SDS-10 steps up to deliver peak power output of 500W using a 10″ custom Sunfire driver that is mated to a 10″ down-firing radiator. Twice the woofers for twice the bass! The SDS-10 incorporates Sunfire’s wide-band, energy efficient Class D amplifier and produces twice the output of its smaller sibling – while only consuming a half a watt in standby. Sunfire’s exclusive FFDTM technology results in superior fidelity, higher output and with lower distortion than the competition.
