PERFORMANCE

High-Fidelity sound
Each LSX II LT speaker uses a version of KEF 11th generation Uni-Q driver array specially designed for this loudspeaker. This signature technology acts as a point source, where the tweeter is placed at the precise acoustic centre of the woofer, recreating how sound is produced naturally. This design eliminates the traditional, tiny ‘sweet spot,’ instead delivering accurate, pristine sound to all listeners.
LSX II LT has a combined 200 Watts of system power. Both the primary and secondary speakers are equipped with dedicated amplifiers for the tweeter and woofer, ensuring the delivery of room-filling sound in its remarkably compact cabinets.
Performance is further enhanced by the Music Integrity Engine. This cutting- edge collection of bespoke Digital Signal Processing algorithms is optimised for the Uni-Q driver, enabling the LSX II LT to deliver a perfectly timed performance, resulting in better clarity and a tighter, more accurate sound.
