KEF LOUDSPEAKERS What to look for when choosing your speakers Of all the elements in your audio system, changing your speakers your kind of music or film soundtrack in your room at the volume can make the biggest difference in sound quality. As a rule of you most enjoy. Although technical specifications are helpful, thumb, the speakers in a basic two-channel hi-fi system often you can only find which model best suits your personal account for about a third of the total system cost.
The continuing evolution of KEF’s legendary Reference Series has always been based on the concept of benchmark precision. Every time a new generation of models is developed to incorporate more sophisticated technologies, we build prototypes that are as close to perfection as possible. These then become the ‘Reference’ to which every With only midrange frequencies to handle, movement of the Uni-Q cone is so modest that virtually no distortion is caused by intermodulation with the tweeter.
Model 207 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.
Model 201 All the latest Reference Series technology packed into a neat bookshelf package. The same sophisticated elliptical titanium dome Hypertweeter. The same carefully damped cast aluminium enclosure for the 5th generation Uni-Q driver, with its thermoplastic rubber surround moulded on to the cone to avoid the slightest acoustic discontinuity. The same ultra-low distortion LF motor systems for bass power with un-compromised accuracy. There’s certainly no compromise on build quality either.
The look of XQ - an evolution of the new Reference Series But hey - when the technology inside creates such beautiful aesthetic - is about function, not fashion. From the chromed steel sound, they deserve to look special. Hypertweeter pod to the curves of the cabinet, everything is With all models magnetically shielded and identically voiced, calculated to produce a cleaner, purer sound. the XQ Series fills the room with the kind of breathtaking Admittedly, the finish is a bit of an extravagance.
The latest evolution of the acclaimed Q Series demonstrates how Uni-Q ‘pod’ and curved section cabinets, echoes the latest the listening benefits of KEF technology leadership cascade down Reference series. Every model features a new design of from the Reference Series to more affordable ranges.
Q1 Q2ds All the benefits of the latest Q Series in a compact speaker with the power to fill the room with big sounds. It has the same Uni-Q driver array as the floorstanding models, reproducing the frequency spectrum with virtually no crossover effects. Genuine performance - and great value. The new Q2ds dipole surrounds create the perfect ‘diffuse’ surround effect, as experienced in movie theatres, by utilising two 165mm (61/2”) Uni-Q arrays.
POWERED SUBWOOFERS The Powered Subwoofer (PSW) plays a vital part in exploiting the styling to match. In each case, both frequency cut-off and output full potential of DVD and other digital formats. The KEF range levels are easily adjusted to match the main speakers and offers logical steps in amplifier power, and bass performance with room acoustics.
