Model 207
Atrue five-way design, the 207 is instantly recognisable by the cast aluminium pod, which is shaped to damp the internal sound field of KEF’s new generation Uni-Q upper midrange driver.
Beneath the state-of-the-art elliptical profile titanium Hypertweeter, a bonded Uni-Form cone/surround provides the optimum waveguide for the 25mm (1”) titanium dome HF unit leading to exceptional vocal clarity.
The lower midrange driver is derived from the LF unit, KEF’s lightweight neodymium magnet
Model 205
In all the other Reference Series models, the wide dispersion Uni-Q/Hypertweeter pod is faired into the cabinet itself.
As in the 207, advanced computer modelling techniques were used to optimise the elliptical profile of the titanium dome tweeter, whose output is fine tuned to the Uni-Form wave-guide. It makes the human voice sound so real and so close that you start looking around for the source.
For the smoothest possible response, much attention has been paid to evening out flux profiles. Both MF and HF coils in the Uni-Q driver share a compound twin neodymium
magnet assembly, and the two ultra-low distortion 200mm (8”) bass drivers have balanced Faraday loops above and below the coil to ensure perfect symmetry. Both long-throw bass drivers operate in parallel at low frequencies where throw is critical, but the lower unit is rolled off early to allow the top LF driver to dominate at the crossover to the midrange unit for the smoothest possible integration.
The listening experience is spine-tingling, off-axis as well as on.Wherever you sit in the room, there’s a near perfect illusion of presence - exactly what you want for auditorium quality home theatre or to recapture that elusive live concert ‘feel’.
assembly allowing it to be effectively decoupled from the cabinet to improve imaging and integration while minimising colouration.
Both long-throw 250mm (10”) bass drivers have their own dedicated enclosures, tuned to different frequencies for better performance in real rooms. With a combined cone area equivalent to a single 375mm (15”) cone, they deliver staggering bass extension of exceptional purity.
Incredibly lucid over an expansive sound stage, with no discernible distortion - whatever sounds you’re into, this is a supremely musical performer.
Model 203
The 203 shares all this technical virtuosity, only on a slightly smaller scale.
Computer matched high order four-way crossovers assure fluid transitions between the five drivers. The Hypertweeter and the new Uni-Q coincident source array together provide seamless mids and highs while the two high-tech 165mm (61⁄2”) LF drivers with KEF’s high-tech motor systems and stiff, lightweight reinforced diaphragms, deliver deliciously open bass with incredibly low distortion even at high volume.
The curved section cabinets are massively braced to eliminate box colourations, and the open chassis design of the drive units with vented cones eliminates any trapped air
noise. Magnetically shielded like the rest of the range, the 203 combines heavyweight muscle with intricate delicacy right across the frequency range. Stereo imaging is superb, the detailing immaculate and the response so fluid you could almost drink it.
