KEF C4 Subwoofer - Walnut

A formidable powered subwoofer
Unobtrusively handsome, yet powerful, the new C4 subwoofer provides an incredible bass output with immaculate control. With a 200 W on-board amplifier driving a 200 mm (8 in.) front-firing bass cone, the C4 is engineered to minimise distortion as meticulously as the rest of the range and adds effortless depth and weight to any performance.

Over four decades of innovation and a passion for engineering excellence has established KEF as one of the most respected names in
high-end audio.
The ideal that inspired KEF’s founder Raymond Cooke in 1961 was to reproduce recordings so accurately that they sounded indistinguishable from live performance, which is why so many professionals (including the BBC) adopted his groundbreaking designs. This spirit of continual innovation in pursuit of perfection is what has driven KEF engineers ever since. KEF speakers are like no others, and few manufacturers have pioneered as many breakthroughs in loudspeaker design - from radical new cabinet designs, cone materials and driver configurations to the use of aerospace technologies and advanced sonic modelling techniques.
So the new C Series is the product of a multi award-winning heritage of daring design, brilliantly executed. Today, it finds expression in revolutionary concepts like the KEF Muon, where ultra-sophisticated driver arrays are shrouded in giant Ross Lovegrove-designed towers of super-formed aluminium.
INCREDIBLE PERFORMERS - WHATEVER YOUR TASTE…
The beauty of the C Series is its exceptional versatility.
The range is engineered for a perfect tonal match between every model, so you can combine them however you please. Using the ingenious and highly flexible C6LCR (left/centre/right) for all five main speakers, for example, gives you a home theatre system of truly epic capabilities. Not only does it deliver precise and engaging vocals but it is also adept at producing a rich and extensive performance enviable of any satellite speaker.
Ease of use and flexibility have been engineered into all C Series models from front firing ports for closer positioning to walls, to the discreet wall mounting brackets fitted to each of the bookshelf speakers. Even the floorstanders are supplied with dedicated plinths to provide greater stability.
Acoustically the C Series provides the sort of clarity, definition and spatial precision normally associated with speakers of a much higher price. Power handling is uniformly excellent, so they’re easy to drive with virtually any amplifier and whether used for music, movies or games, the sheer quality of the sound they produce is equally captivating.
FEATURES
ULTRA-RIGID ENCLOSURES
The sound you hear is untainted by any internal resonance from the sturdily constructed cabinet, thanks to careful internal bracing and a dense dual-layered baffle system.
MAGNETIC SHIELDING
Freedom of positioning is virtually unrestricted because every C Series speaker is fully magnetically shielded to eliminate any risk of interference with other electronic devices in the room.
GOLD-PLATED TERMINALS
The exceptional acoustic definition you experience depends on the recorded signal being perfectly transmitted, so the twinned binding
posts of the C Series are gold-plated.
FORWARD-FIRING SLOT PORT
Bass response is further extended by a frontal slot port carefully contoured to maximise low frequency dispersion and minimise any unwanted turbulence that might otherwise colour the well-defined output of the bass drivers.
