Twin 9 inches driver 'force-cancelling' subwoofer

Delivering exceptional bass precision and control with zero distortion, Reference 8b is a truly extraordinary subwoofer.
For power with accuracy the Reference 8b sub has two 500W Class D amplifiers, each driving a 228mm (9 inch) long-throw, ultra-low distortion driver. These are connected back-to-back in a heavily braced, acoustically inert cabinet. The result is low distortion bass with effortless body and weight.
KEF is a British loudspeaker manufacturer that produces a range of high-quality audio products, including home theater speakers, stereo speakers, and headphones. The company was founded in 1961 and is headquartered in Maidstone, Kent, England. KEF is known for its innovative loudspeaker designs, which incorporate advanced materials and technologies to deliver high-quality sound. For example, KEF's Uni-Q driver technology places the tweeter in the center of the midrange cone, resulting in a more coherent and accurate soundstage. The company also uses materials like aluminum, magnesium, and carbon fiber to create rigid and lightweight speaker cones that minimize distortion. KEF offers a range of products to suit different needs and budgets, from its affordable Q Series speakers to its high-end Reference Series. The company's products are also designed to be visually striking, with sleek and modern designs that complement contemporary home decor.
