Best In Show
Born from high fidelity performance and bred especially for home theater systems, the Ci Series Ci9000ACE is the best of KEF's best. Not just a set of mangy components beneath a groomed exterior, the Ci9000ACE uses the exact same Uni-Q array as found in the purebred XQ series speaker.
Customize Your Audio Ride
The hot rod of the Ci series, the Ci9000ACE was built to be customized. Specifically designed for flush mounting into walls and ceilings, the Ci Series delivers KEF audio quality as unobtrusively as possible without losing any sound quality. The Ci series even comes with three grille options: white, black cloth, or—the ultimate in customization—the paintable grille. Pretty tempting to put some flames on these bad-boys, isn't it?
KEF's Ci Series Custom-Install Speakers
Since all models are designed to withstand harsh environments such as bathrooms or even outside (under the eaves), there's virtually no limit to the design possibilities they open up. And with KEF's simple and ingenious mounting system, you'll also find them amazingly easy and rapid to install.
Acoustic Compliance Enhancement (ACE) Explained. . .
The holy grail of loudspeaker design has always been to generate big bass from small boxes. The trouble is, the laws of physics make this almost impossible to achieve, as bass extension relates directly to efficiency and cabinet size. Continuing a 40-year tradition of genuine design innovation, KEF engineers have now developed a way of overcoming this apparently insoluble limitation. It's called Acoustic Compliance Enhancement (ACE), and it works like this: in conventional speakers, cone motion is restricted by the acoustic pressure in the enclosure as the air is alternately compressed and expanded by the cone moving in and out. The smaller the enclosure, the greater the pressure that acts on the cone. By dramatically reducing this pressure, ACE allows the cone to move as freely as it would in a much larger cabinet, generating bass extension out of all proportion to its actual size. This is achieved by introducing granules of activated carbon into the enclosure—a material containing millions of pores ranging in size from visible fissures to holes a few molecules across. By introducing activated carbon into the enclosure of a loudspeaker, the effective compliance of that enclosure can be enhanced at low frequencies by between 150% and 300% in a practical design. With ACE, the drive unit behaves as if it were in an enclosure up to three times the size of the actual enclosure. In layman's terms, what you get out of all this is enhanced mid-range definition and extended bass response.
Uni-Q Array Explained. . .
KEF's Ci series incorporates the Uni-Q technology, something originally designed for one of the world's finest speaker models, KEF's legendary Reference Series. With each generation of speakers, KEF expands on and improves their Uni-Q offerings. The Uni-Q concept is based on using aerospace materials to make the tweeter small enough to place at the acoustic center of the bass/midrange cone. With both drive units on exactly the same axis and sharing the same waveguide, they behave as a single point source that projects a more natural sound image over a much larger area than the usual tiny sweet spot.
