The Q400b subwoofer is the final step to achieving a truly immersive home cinema audio experience at an accessible price. The Q400b is simply seductive, offering a superlative performance of liquid-like bass, complete with the same level of control and sophistication that one would expect from any product made from KEF.

The Q400b's 250mm woofer is driven by a capable 200W Class-D amplifier, housed within a closed-box design. This unobtrusive cube is designed to match the other models within the Q series flawlessly, and adds a new depth of dynamic superiority to what is already a superb set of loudspeakers.
