Product Description
The KEF LS50 Meta Royal Blue is a 2-way bookshelf speaker that represents the pinnacle of KEF's audio engineering. If you are looking for a premium speaker with revolutionary technology, reference-grade sound, and an iconic design, this is your ideal speaker.
Revolutionary Meta Technology
First Generation of Speakers with Metamaterials
The LS50 Meta is the world's first bookshelf speaker with metamaterial absorption technology. This revolutionary technology absorbs 99% of unwanted noise coming from the back of the driver, eliminating internal reflections that color the sound.
Pure and Transparent Sound
By eliminating background noise, Meta technology allows you to hear the music exactly as it was recorded, without coloration or distortion.
Advanced 12th Generation Uni-Q
Latest Generation Uni-Q Driver
The 12th generation Uni-Q driver places the tweeter in the center of the 5.25" woofer. This creates a coherent sound source that provides exceptional stereo imaging and excellent off-axis dispersion.
Exceptional Sound Imaging
The Uni-Q configuration allows you to hear the same sound image from multiple listening positions, not just from the central "sweet spot."
Premium Aluminum Drivers
5.25-Inch Woofer
The 5.25" (133mm) aluminum cone woofer provides controlled, precise, and powerful bass and midrange reproduction. Aluminum offers superior rigidity and lower distortion.
1-Inch Vented Tweeter
The 1" (25mm) vented aluminum tweeter provides clear, detailed high frequencies without listening fatigue. The vented design improves thermal dissipation.
Extended Frequency Range
Ultra-Extended Response
The frequency range is 79 Hz to 28 kHz, providing an ultra-extended response of the human audible range. High frequencies extended up to 28 kHz allow for capturing ultrasonic details that other speakers cannot reproduce.
Deep Bass
The extended bass response allows you to enjoy the depth and impact of the music without sacrificing midrange and high-end clarity.
Optimal Sensitivity and Amplification
85 dB Sensitivity
The 85 dB (2.83V/1m) sensitivity is efficient, allowing it to perform well with quality power amplifiers.
Optimal Amplifier Requirements
Amplifier requirements are 40 to 100 watts, providing the ideal range for quality integrated amplifiers and dedicated power amplifiers.
High Maximum SPL
106 dB SPL
The maximum SPL is 106 dB, providing enough volume to enjoy dynamic music without distortion, even in large rooms.
8 Ohm Nominal Impedance
Wide Compatibility
The 8 ohm nominal impedance (3.5 ohms minimum) is compatible with most quality amplifiers, providing maximum amplification flexibility.
Iconic Design
Royal Blue Special Edition Finish
The Royal Blue finish is a special edition that provides an elegant and distinctive look. Also available in Carbon Black, Titanium Grey, and Mineral White.
Premium Construction
The cabinet is constructed from superior quality MDF and a convex plastic composite front that reduces diffraction. The design is iconic and instantly recognizable.
Low-Diffraction Curved Baffle
Optimized Acoustic Design
The curved and convex front reduces diffraction caused by sharp edges, providing a more neutral and transparent sound.
