KEF has expanded its subwoofer lineup for 2024, introducing five new models designed to cater to a wide range of budgets and room sizes. Among these new releases are the highly anticipated KEF KC92 Force-Cancelling Subwoofer and the Kube Subwoofers, which promise to deliver immersive sound experiences for music, movies, and gaming enthusiasts alike.
Central to the performance of these new subwoofers is KEF's proprietary Digital Signal Processing (DSP) algorithm, known as the Music Integrity Engine (MIE). Custom-tailored for each model, MIE ensures optimal synergy among the subwoofer's components, resulting in detailed and accurate sound reproduction across the frequency spectrum.
The KEF KC92 subwoofer builds upon the success of KEF's previous models, particularly the popular KC62 compact subwoofer. Featuring a dual-driver arrangement mounted in a force-canceling (Uni-Core) assembly, the KC92 delivers extended bass performance and impactful sound reproduction while maintaining a relatively compact form factor.
Powered by 1,000 watts of Class D amplification (with a dedicated 500W amplifier for each driver), the KEF KC92 offers precise control over bass output, enhancing timing accuracy and dynamic response for a more detailed listening experience. The inclusion of KEF SmartConnect ensures seamless integration with a variety of audio systems, while five room placement options enable flexible positioning to suit any environment.
For those seeking a more affordable option, KEF's Kube Subwoofers offer a range of sizes and configurations to accommodate different room sizes and audio preferences. Available in 15", 12", 10", and 8" driver sizes, the Kube lineup boasts features such as long-throw drivers, sealed cabinet designs, and placement-dependent EQ adjustments, all optimized for maximum in-room performance.
With Class D amplifiers providing efficient power delivery and versatile connectivity options including line-level and speaker-level inputs, the Kube Subwoofers offer versatility and ease of integration into any audio setup. Optional accessories such as the KW1 wireless subwoofer adapter further enhance convenience for users seeking a cable-free solution.
