The KEF Model 105/3, a floor-standing speaker system embodying several advanced and unconventional design features, is the newest member of the company's Reference Series. A fairly large column-shaped speaker, the 105/3 weighs more than 92 pounds. Its walnut-veneered cabinet, which stands 43-1/2 inches tall and measures 11 inches wide and 16 inches deep, is handsomely finished on all visible surfaces. The cabinet is constructed of 22-millimeter (about 7/8-inch) particleboard and is fitted with four spiked feet with removable plastic caps to protect finished floors. For use on carpeted floors, KEF recommends that the caps be removed once the speakers have been placed.
The KEF 105/3 is a four-way system rated for very high sensitivity, high acoustic-output capability, and exceptional power-handling capacity. Its bass section consists of two upward-facing 8-inch drivers; they are mounted within the cabinet in the double coupled-cavity configuration first introduced by KEF in its top-of-the-line Model 107 speaker system. The drivers' magnetic structures and frames are linked with a rigid force-canceling rod (about a half-inch in diameter) that is said to reduce acoustic distortion and the transfer of energy from the woofers to the cabinet walls. The combined output of the two woofers is radiated through a smoothly contoured molded duct, about 6 inches in diameter, that acts as an air diaphragm of very low mass.
The other drivers are housed in a separate module, about 10 inches wide and 22-1/2 inches high, that is machined from a solid piece of 3-inch-thick fiber material. This section of the speaker is mounted on the front panel of the cabinet, extending from the top of the bass port to the top of the cabinet. Like most of the front of the speaker, it is hidden from view by the black cloth grille, which is retained by magnetic fasteners and is easily removable. The grille structure weighs a surprising 4-3/4 pounds.
The lower-midrange frequencies are handled by two 6-1/2-inch cone drivers near the top and bottom of the front-mounted module. Between them is a KEF Uni-Q driver, with a concentric 6-1/2-inch cone and 1-inch dome tweeter. The tweeter's tiny, powerful neodymium magnet allows it to fit within the voice coil and magnet structure of the cone driver, placing the middle- and high-frequency sound sources in the same plane. The Uni-Q design is said to minimize crossover discontinuities and provide similar directional coverage in the crossover region for the outputs of the two concentric drivers.
The symmetrical, vertical placement of the lower-midrange speakers around the Uni-Q mid/high-frequency driver are said to give the Model 105/3 system the highly desirable properties of a broad, uniform horizontal radiation together with a narrower vertical radiation pattern in the midrange, where the acoustic sources of all four drivers appear at the same point in space (the center of the middle driver). This point is about 31 inches from the floor, roughly on a level with the ears of a seated listener.
