A 14-Inch-Square Knockout: Award-Winning KEF Powered 400b Subwoofer Delivers Fast, Impactful, and Clean Bass Driven by Twin Nine-Inch Drivers and Fueled by Twin 250W Amplifiers

In this corner, weighing 47.4 pounds and measuring only 14 inches square, is the punchy, fast, impactful, and delightfully compact KEF R400b subwoofer. Tailor-made to pair with its Reference Series tower-speaker counterparts, the sealed-design R400b touts twin nine-inch low-frequency drivers fueled by twin 250W Class D amplifiers. Back-to-back mounting of the drivers creates a force-cancelling effect that nullifies opposing reactive forces, eliminating cabinet resonance and producing clean, powerful bass that elevates the spatial breadth and emotional resonance of any home-theater system. Named a Sound + Image highly commended component and Home Theater Top Pick, R400b fits into music setups equally well and gives you a harmonic complement that increases the naturalism, completeness, and dynamics of every song you'll play. A reinforced and sealed cabinet, along with elegant looks, crowns a subwoofer that will give you the extra bursts of realism that makes films and recordings that much more enjoyable. 100% Music Direct Guaranteed.
