KEF LS50 – Legendary Bookshelf Precision
The KEF LS50 isn’t just a bookshelf speaker—it’s a sonic benchmark. Born from KEF’s 50-year engineering legacy, the LS50 delivers startling clarity, a wide soundstage, and effortless dynamics in a compact cabinet. Perfect for hi-fi enthusiasts who demand detail, precision, and impact in any listening space.
Why the LS50 Stands Out:
- Uni-Q Driver Technology – KEF’s iconic coaxial driver places the tweeter at the acoustic center of the midrange cone, giving you pinpoint imaging, natural sound, and a wide, immersive soundstage. Instruments appear in space, not just as sound.
- Compact Yet Powerful – Small footprint, huge personality. Tight, controlled bass and sparkling highs come from a carefully engineered cabinet, proving that size isn’t everything.
- High-Fidelity Engineering – Every curve, every material, every damping choice is optimized for low distortion and smooth, accurate response across the spectrum. You hear the music, not the speaker.
- Design Meets Function – Clean, modern lines with premium finishes. The cabinet shape reduces resonance and diffraction while looking stunning on a bookshelf or stand.
- Flexible Integration – Works beautifully with a wide range of hi-fi amplifiers or AV receivers. Thrives in both stereo and home cinema setups.
At The Audio Experts, we believe that great sound is about both technical excellence and emotional impact. The LS50 lets you hear everything—the whisper of a vocal, the breath of a saxophone, the shimmer of a cymbal—as if you’re in the room with the artist. Compact, precise, and utterly addictive.
Ultra Nerd Tech Specs
- Speaker Type: Passive Bookshelf – Requires external amplification. Using a quality amp allows full control over dynamics, transient response, and tonal balance.
- Drivers: 12th-generation Uni-Q coaxial driver (25mm aluminium dome tweeter + 130mm midrange) – The coaxial arrangement ensures phase coherence across frequencies, resulting in a precise soundstage and accurate imaging. Your brain perceives instruments exactly where they should be in space.
- Frequency Response: 79Hz – 28kHz ±3dB – Smooth, extended highs for air and sparkle, tight lows for rhythm and depth. Even subtle overtones are rendered clearly, giving realism and texture to every track.
- Nominal Impedance: 8Ω – Optimized for a wide range of amplifiers. Matching the right amp ensures controlled driver movement, minimizing distortion and maximizing dynamic range.
- Recommended Amplifier Power: 30 – 100W – Enough headroom to handle dynamic peaks cleanly. Underpowered amps may limit bass response and transient speed.
- Sensitivity: 85dB (2.83V/1m) – Efficient enough for modest amps but still capable of producing room-filling volume with accuracy.
- Cabinet: Curved MDF with constrained-layer damping – Reduces cabinet resonance, diffraction, and coloration. Ensures drivers do the work, not the enclosure, for precise tonal balance and imaging.
- Port Design: Slot-loaded rear bass reflex – Tuned for tight, controlled low-end extension without boominess. Your bass is deep, accurate, and in rhythm with the music.
- Dimensions: 302mm H x 200mm W x 278mm D – Compact yet acoustically optimized, balancing internal volume for bass extension and controlled dispersion for imaging.
- Weight: 7.2kg per speaker – Solid, stable construction reduces vibration, keeping drivers stable and maintaining tonal clarity.
- Included Accessories: Spikes, magnetic grille, and user manual – Proper isolation with spikes enhances bass control, and the grille protects the drivers without affecting sound.
