Benefits of KEF Reference 4C Center Channel Speaker:

Uni-Q Driver technology

Featuring a state of the art vented dome tweeter that is a mere one inch in size and is placed at the exact acoustic centre of a highly sophisticated 5 inch mid range driver, the Reference 4C can flood a sound field with pure, unadulterated sound - no matter where the listener is seated. But that's not all! Reference 4c pairs KEF’s latest MF/HF Uni-Q driver array with four sensational alloy cone bass drivers to create a compellingly realistic and completely immersive sound stage. The Reference 4c's Uni-Q cast an inherently wide, even dispersion that also makes it a tremendous centre channel speaker in a home theater system.

Advanced Bass technologies


Featuring a world class 6.5 inch driver with a massive magnet assembly and a large aluminum coil wire, the Reference 4C is a hub for advanced bass technology. Played loud or soft, in delicate passages or for full-on bass effects, the combination of advanced materials and clever engineering delivers deeply rewarding lows that blend seamlessly with Uni-Q’s immaculate mid range and treble response.

Cabinet design

While performance determines if a speaker is worth purchasing, it also needs to be aesthetically pleasing. The Reference drivers are set in a smooth, strikingly distinctive front baffle engineered to eliminate response anomalies caused by diffraction. Made from an exceptionally strong laminated aluminium/resin composite and secured via high-loss pads and high tensile bolts, it adds tremendous rigidity to the inert cabinet. Handmade pair matched wooden banners add a finishing touch to the cabinet walls. Finally, a constrained layer of damping absorbs residual vibrations thereby allowing you to experience the purest of sound.

Flexible Port technology


Featuring award winning technology that was specially designed and crafted for the LS50 by Reference, the Reference 4C sets unmatched standards in reducing mid range port resonance. Carefully calculated fluid dynamics help avoid turbulent air noise thereby ensuring you don't compromise on the purity of sound. What's more? 

The Reference has innovative adjustable ports for fine-tuning the bass output to your personal taste.

Crossover design 

You can't rush perfection and KEF knows that! Each high grade component goes through exhaustive individual and collective auditions before being brought together in the deference 4C. This allows the smoothest response with the lowest distortion - exactly what you want from a centre channel speaker.
