The 12. Powered Subwoofer brings music, movies, and video games to life with an immersive bass experience that you can not only hear, but truly feel. With a front-mounted woofer and efficient all-digital 300 watt amplifier, the NV-SUB12 adds a deep and detailed low-frequency impact to custom home theater or audio installations. Its sealed cabinet is constructed of durable MDF for a distortion-free, superior bass response and features a multi-coat high gloss black finish. The NV-SUB12 features signal-sensing power activation to automatically turn on the subwoofer when it receives a signal from the receiver and return it to standby after 15 minutes of no signal. Offering maximum versatility, the Powered Subwoofers were designed to integrate with almost any audio system. Unfiltered LFE / RCA stereo input and output let you easily connect to most modern receivers. And a convenient USB jack can power an optional wireless receiver. The variable crossover and phase adjustments allow you to match the Subwoofer output with the main speakers for premium performance and sound.
