AudioSource AST-SUB10 150-Watt Powered Subwoofer with 10" Woofer (Single Speaker)

The sub accepts line-level (RCA) or speaker-level inputs, depending on your needs. A continuously variable crossover lets you pick a crossover point between 50 and 180 Hz to match the upper range of the speaker's frequency response to the low-frequency output of your other speakers. If you're using a surround receiver with a dedicated subwoofer output, you can bypass the AST-SUB10's crossover altogether for the most accurate reproduction of your receiver's LFE (low-frequency effects) signal.

The subwoofer is constructed of 0.75-inch high-density press board. A side port lets the woofer move more air for greater bass output, and the AST-SUB10's internal bracing minimizes unwanted resonances, which can unfavorably color the sound. Other features include output volume control and phase switch (0/180 degrees for help in integrating the sub with your other speakers, depending on its position), auto-sensing power on, an LED power indicator, custom isolation spikes (use is optional), and a multi-voltage power input.
