The SubSeries 250 is a 10-inch (254 mm) subwoofer that uses a 200-watt Class D amplifier with built-in DSP to add a powerful beat to your hi-fi or home theater system. Designed with a high-performance polypropylene woofer and intelligent bass-limiting circuitry that prevents the sub from overpowering, the SubSeries 250 delivers powerful bass with stunning accuracy at room shake levels down to 20Hz. Thanks to its discreet compact design and low-pass driver, this premium-looking yet affordable subwoofer can be easily integrated with existing speaker systems and blend seamlessly into any space.
