Pair the Wharfedale SW-12 Active Subwoofer with Diamond 11 or D300 Series Speakers for Amazing Synergy: Performance Fueled by 12-Inch Long-Throw Driver and Powerful 300-Watt Amplifier The sonic benefits that come from adding an audiophile-quality powered subwoofer to a stereo or home-theater system are legion.

Want proof? Try the Wharfedale SW-12 in your home during a risk-free audition and hear the difference.

An ideal match for the company's Diamond 11 and D300 Series loudspeakers, and able to deliver a powerful 300-watt output by way of its advanced amplifier and astute 12-inch long-throw driver, SW-12 completes harmonic notes, fully extends bass lines, offers added weight, and helps bring music and movie sound into better focus.

It plays with impressive speed while maintaining its composure even during demanding passages. Wharfedale built SW-12 with non-pressed paper cones to enhance self-damping, improve transient impact, and increase the structural rigidity of the cone itself.

SW-12's center vents are lined with copper to reduce the magnetic distortion and improve heat dissipation. On the back panel, two line-in inputs, a mono line-in input, and a phase inversion switch complement handsome looks and a continuously variable crossover that provides easy integration with existing loudspeakers.

Measuring 19.2 x 15.6 x 18 (HWD), and weighing nearly 49 pounds, SW-12 is one mighty cube. 100% Music Direct Guaranteed.
