Clear, confident and natural sounding, the C3 boasts KEF’s 130mm (5.25in) bass driver for impressively extended low frequency response to complement the seductive realism of the sophisticated 19mm (0.75in) tweeter and ‘tangerine’ waveguide. The resulting sonic performance is warm, rich in detail and compellingly three-dimensional, whether you’re enjoying a favorite track or watching a movie. All of the C Series enclosures are ultra-rigid to ensure the sound you hear is untainted by any internal resonance and all are magnetically shielded to give freedom when positioning.

Aluminum dome tweeter with ‘tangerine’ waveguide

The same 19mm (0.75in) tweeter from the latest Q series reproduces vocals with spellbinding realism – the unique ‘tangerine’ waveguide disperses its sweet natural clarity evenly throughout the room and provides excellent protection from straying fingers.

Gold-plated terminals

The exceptional acoustic definition you experience depends on the recorded signal being perfectly transmitted, so to eliminate the risk of tarnishing, the binding posts of the C Series are gold-plated.

Invisible wall mounting system

With no ugly brackets to spoil the clean lines, it couldn’t be easier to secure your C Series satellites (upright or horizontally) to any suitable vertical surface using the ingeniously neat keyhole mounting point built into the back of each cabinet.

Open Box, Acoustically Perfect with Cosmetic Imperfection

Buying a KEF open box product is a great way to get "like-new" products at a considerable savings. Every product has been thoroughly tested, cleaned and otherwise renewed to original condition. Next it’s repackaged in a new box with all original accessories included. And for your piece of mind and protection, your purchase is covered by a full 5 year parts and labor warranty (1 year on electronics) valid at any authorized KEF repair center (you can look-up locations online here or call 732-683-2356)

All units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10) unless otherwise stated. Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked cabinets, broken grilles, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
