This mini subwoofer adds deep bass excitement and extended dynamic thrills to your music or movie sound system with the easy-to-connect and easy-to-use Polk Audio subwoofer solution. These are compact, active subwoofers engineered for limited distortion. This small subwoofer speaker packs a 10 inch sub inside a non-resonant cabinet, delivering deep, smooth response with superior detail. The 10 in subwoofer is driven by a high-current amplifier generating 50 Watts RMS/100 Watts dynamic power, giving you a reliable sub amp combo within a single powered sub design. A rotary control lets you match output to the rest of your setup, while a continuously variable low-pass filter (80-160 Hz) supports seamless subwoofer home theater integration. Easily accessible line- and speaker-level inputs and outputs simplify hookup to stereo or sub woofer systems, making this ideal for rooms that need impactful yet space-saving sound.
