Blow the roof off (it's just plain going to happen with the Q900) with KEF's towering 200W performer. Perfectly capable of taking on complex audio, the Q900 provides clear vocals and articulate midrange response as well as mammoth bass for dynamic imaging worthy of even the most demanding home theater system.

Performance that's completely out of the box

The KEF Q Series floorstanders have a sound so big, so clear, and so outstanding, you won't believe it's resonating from a single point in the room. Configured with the newest generation of the Uni-Q array, the Q Series floorstander comes complete with the mid/high Uni-Q array plus a long-throw bass driver and two matching auxiliary bass radiators (ABRs) for one seriously intense soundstage. Add this bad boy to your current KEF setup or make it your maiden KEF voyage. It doesn't matter, once you get hooked on KEF, you'll be one spoiled little audiophile.

Uni-Q: every seat in the room is the sweet spot

KEF's latest version of the Uni-Q array uses state-of-the-art technology (and makes it affordable). The vented tweeter design makes clarity a priority and insures a smooth transition to midrange frequencies thanks to KEF's Stiffened Dome technology. Adding the new Tangerine Waveguide to the tweeter protects the dome and improves the efficiency and sound dispersion at the highest frequencies. Matched directivity (mounting the tweeter in the center of the bass driver) improves the uniformity of the tonal balance across the listening area — improving off-axis stereo imaging. For lows and mids, the new aluminum driver cones and large aluminum voice coils deliver fast, clean response at high power levels. The Z-flex surround gets rid of the conventional half-roll and adds one that allows simple deformations at low frequencies, but resists complex deformations in the midrange. The result is clear, unsmeared sound. But, beyond all this techno-speak, the Uni-Q array does one thing and does it well — disperse sound evenly throughout the room. It's like playing duck-duck-goose where everybody's a winner.

Crossover — simply good acoustic performance

If you've ever peeked inside a speaker cabinet, you may be tempted to decry the simplicity of the design. Interestingly enough, the simpler the crossover design, the better the acoustic performance. And we're saying simple, not cheap. The whole point of a crossover network is to filter the input signal to the separate bass, midrange, and treble drivers and to provide overall equalization and good tonal accuracy. For the Q Series, KEF put together lower, second order (i.e. a construction that uses the least amount of components) crossovers with simple electrical filter topologies for free-flowing, unconstrained, and dynamic swings and a big, open stereo image with believable overall geometry. How do they get away with using lower order crossovers? They know that carefully designed drive units and enclosures ensure only minimal filtering is necessary: genuinely good high-performance drivers = the realization of the full potential of low order acoustic crossovers. More simply put, KEF is all quality, and you don't have to be an engineer to hear the difference (thankfully).

Sound engineering — inside and out

What may seem a Herculean task to the non-engineer was undoubtedly down-right fun for the developers at KEF. Beyond the high-performance components, KEF has taken care of every single detail, right down to the top-side adjustable floorstander spikes. The cabinets are ultra rigid with 30% more internal volume for the best bass and midrange response. The gold-plated bi-wire terminals provide the clearest signal transmission possible. And the sexy, exotic, and very guilt-free wood veneers that consist of recycled wood fiber instead of unsavorily harvested hardwoods. (Hey, just because KEF provides luxurious sound doesn't mean they have to take more than their share.) KEF knows it's in the details. It's not just an experience. It's a KEF experience. Kind of gives you that warm fuzzy feeling, doesn't it?
