At the heart of LS LUXE sits a 12th generation 6.5-inch Uni-Q driver array with MAT. This signature technology delivers a true point-source configuration, with the tweeter precisely placed at the acoustic centre of the woofer, ensuring uniform sound dispersion throughout the room. At the same time, MAT functions as an acoustic black hole, absorbing 99% of the unwanted sound energy from the tweeter’s rear radiation. This reduces interference and results in a cleaner, purer sound.
The Uni-Q assembly is mechanically decoupled from the cabinet to minimise panel vibrations that could otherwise generate audible distortion. Incorporated within the Uni-Q assembly is a bespoke flexible decoupling chassis arrangement that decouples and dampens the vibrations of the LMF motor, preventing them from exciting the cabinet panels.
Together, these innovations and refinements deliver an exceptionally wide sweet spot, uncannily natural sound with vanishingly low distortion.
Velocity Control Technology (VECO), KEF’s sound correction technology first introduced in the XIO soundbar, is now featured in the LS LUXE. VECO utilises a closed-loop feedback amplification system, combining KEF’s patented velocity sensor and a custom current-drive amplification stage within both primary and secondary speakers. The velocity sensor measures the real-time cone motion, feeding this data to the amplifier, which instantly corrects any discrepancies between the input signal and the cone’s motion. This real-time monitoring and negative feedback loop ensures that the signal reaching the driver’s voice coil includes both the intended musical signal and necessary corrections, significantly reducing distortion and compression. The result is pristine clarity and a more linear, accurate bass performance at all times.
To further refine performance, KEF’s MIE—a proprietary suite of DSP algorithms—has been specially tuned for the LS LUXE, enhancing sound integrity, detail, and accuracy. This custom implementation is tailored specifically to suit the LS LUXE’s acoustic and electronics package, providing excellent dynamic control that ensures consistent tonality regardless of playback level or duration.
LS LUXE features a highly optimised package of 100W Class AB and 280W Class D current-drive amplifiers in each speaker, which directly control the cone’s motion by regulating the current delivered to the primary voice coils of the tweeter and the LMF drivers, respectively. This design results in lower distortion and a cleaner sound.
