Compact, versatile, and potent. Each speaker in the C1 bookshelf pair combines the superbly accurate 0.75" tweeter with "tangerine" waveguide with a slot-ported 4.0" midrange/bass driver and dense two-layer front-baffle system to deliver a complex, profoundly realistic, and spatially accurate soundscape. With excellent power handling and a carefully tuned crossover, this KEF C series speaker pair delivers a generously full performance that belies its discreet appearance and modest size.

Its size might be discreet, but its audio . . .

When you first began dreaming up your surround sound home theater, you weren't imagining surround sound effects that when whiz and pop. Au contraire! You had visions of effects that went ZOOM, BANG, and CRASH! Combining an improved 0.75" tweeter with a 4.0" midrange/bass driver and a front-ported bass-reflex enclosure, each speaker in the KEF C1 bookshelf speaker pair serves up generously full performance, whether from your favorite album or your favorite movie's surround sound track. Further, a whole host of design features showcases the performance potential of KEF's C series speakers.

The C series' foundation

Before we delve into the details of the C1's high- and low-frequency drivers, let's take a quick look at the C series' repertoire of performance-enhancing design features. First on the list: speaker-wire terminals. Not only does each C1 speaker have dual sets of binding posts that accommodate bi-wiring and bi-amplification for clean frequency response, but the binding posts are gold-plated for high-fidelity transmission of your audio signal. Further, built-in invisible keyhole mounting points allow for effortless and seamless mounting of the C1 to any vertical surface. Next, the use of an ultra-rigid cabinet construction and a dense, dual-layer baffle system minimizes internal resonance and unwanted distortion of your favorite audio. Finally, magnetic shielding of the drivers allows all of the C series loudspeakers to be safely placed near your television with no risk of damage to the screen.

A high-frequency medley: tweeters and tangerines

What if a high-frequency driver's soundstage could be widened to fill your entire listening area, while still preserving the integrity of high-frequency audio reproduction? With its new "tangerine" waveguide, the C1's 0.75" aluminum-dome tweeter delivers both a smoother, clearer high-frequency response and an even more expansive audio dispersion, leaving even further behind the notion of an audio "hot-spot." An appropriate first song: Led Zeppelin's "Tangerine", what else?

Full, extended bass

You might think that the folks at KEF would have been just fine, relying on the C1's 4.0" midrange/bass driver to fill out its low-frequency audio reproduction. But the engineers at KEF took things one step further, coupling the dual-woofer system with a front-firing bass-reflex port. While the vibration at the rear side of a driver can result in unwanted resonance and distortion in your audio, bass-reflex systems take advantage of that movement of air to improve audio performance. The C1's contoured front port extends this speaker's bass performance and improves bass efficiency for a full low-frequency effect.
