DESCRIPTION

UNI-Q DRIVER ARRAY THAT JUST HITS THE 'WIDE' SWEET SPOT

The LS50 features KEF's patented Uni-Q driver configuration, in which the tweeter is mounted at the acoustic center of the midrange cone. With both acting as a single point source, the sound is dispersed widely and evenly throughout the listening area allowing you to experience superbly defined and perfectly balanced stereo imagery with a wide sweet spot. The Uni-Q driver array comprises a 1" aluminum vented-dome tweeter and a 5.25" magnesium/aluminum alloy cone woofer.

Headphone-Zone-KEF-LS50

1" ALUMINIUM VENTED-DOME TWEETER + 5.25" MAGNESIUM/ALUMINIUM ALLOY CONE FOR A STRIKINGLY NATURAL SOUND

The geometry of the tweeter dome matches that of the midrange cone to avoid disrupting the waveform. By smoothening high frequency response, this helps to account for the detailed and strikingly natural-sounding treble. The 1" aluminum vented-dome tweeter utilizes a Tangerine Waveguide to encourage the sound to radiate spherically for wider, more even dispersion so that everyone in the room enjoys the same superb sound quality. A large internal vent prevents potentially distorting high pressures from building up behind the dome in the critical vocal region, preserving all the nuance and fine detail of the original performance. The 5.25" woofer uses a magnesium/aluminum alloy cone that is light, stiff, and smooth for natural midrange and midbass sound. As well as allowing the midrange cone its full extension, KEF's ingenious Z-flex surround guides the sound from the tweeter across the surround without any disturbance or secondary radiation. Treble response is clearer and sweeter.

Headphone-Zone-KEF-LS50
Headphone-Zone-KEF-LS50

230W BI-AMPLIFICATION FOR HIGH-FIDELITY SOUND

The Uni-Q driver array is powered by an incredible clean and fast 230 watt amplifier in a bi-amp dual mono configuration. (200 watts to the woofer and 30 watts to the tweeter) that produces high-fidelity sound. The LS50 Wireless speaker system is self-powered, hence each speaker will need to be plugged into an AC wall outlet.

Headphone-Zone-KEF-LS50

ADVANCED TIME CORRECTING DSP

The LS50 Wireless employs an advanced time correcting DSP crossover that corrects for inherent time delays introduced in the crossover stage.

FEA-DESIGNED CABINET AND CURVED BAFFLES FOR HIGH PRECISION, MINIMUM REFLECTION AND A SPACIOUS SOUND

The FEA-designed cabinet with its constrained layer damping bracing and precision engineered curved baffle, along with the elliptical flexible port all work in concert to prevent cabinet vibration and resonances that produce unwanted sound coloration for clear, spacious, distortion-free sound.The curved baffle is shaped so that the sound waves spread from the drivers with minimum reflection from the edges which gives a very nice spacious sound.
The curvature also improves the rigidity of the baffle which reduces vibration and sound coloration.

Headphone-Zone-KEF-LS50

DESIGNED WITH A FLEXIBLE PORT TUBE ENSURING LESS VIBRATIONS, MORE STABILITY

The rear-firing port tube has a flexible wall which allows midrange sound that is travelling down the port tube to escape back into the cabinet and prevents longitudinal resonances; which can otherwise radiate and cause midrange coloration.The port tube also has very carefully flared walls to avoid the chuffing noises which may be caused due to air turbulence inside.

QUAD DAC CONFIGURATION AND SPEAKER EQ MODES TO TAILOR THE SOUND OF YOUR SPEAKERS

The LS50 Wireless features an end-to-end 192kHz/24-bit high-resolution digital signal path with two separate DACs for each speaker, for a total of four for the pair.

Through the KEF LS50 Wireless app for Apple iOS 8.0+ and Android OS 4.1+ you get access to advanced audio settings to expertly tailor the system's sound to your room environment and preference. Select from Desk, Stand, Wall or Free Space.

ADJUSTABLE ROOM ACOUSTICS, ADVANCED BASS-TREBLE CONTROL AND SUB CONTROLS

In addition, you can indicate how far the speakers are from the back wall. You adjust the treble trim from -2dB to +2dB. The bass extension can be set to Less, Standard, or Extra. If you connect a powered subwoofer you can activate a variable high pass (50-120Hz) & low pass (40-250Hz) crossover. You can also adjust sub polarity and sub gain (-10 to +10dB), as well as the balance between subwoofer and speaker. The KEF LS50 Wireless speaker system is equipped with a mono-RCA subwoofer output to connect a powered sub (sold separately).

The LS50 Wireless powered speaker offers an analog stereo RCA output for connection of an analog audio source device.
