Pair of KEF 105/3 speakers and Kube 200 equalizer Made in England from a smoke-free home.
The KEF Model 105/3 is a floor-standing speaker system embodying several advanced and unconventional design features. A fairly large column-shaped speaker, the 105/3 weighs more than 92 pounds. Its 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.
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 specifications of the KEF 105/3 include a frequency response of 49 to 20,000 Hz ±2.5 dB at a 2-meter distance on the reference axis and within 2 dB from 50 to 17,000 Hz up to 30 degrees off the axis in any direction. The system's sensitivity under anechoic conditions is rated for a sound-pressure level (SPL) of 93 dB at 1 meter on the reference axis with a pink-noise input of 2.83 volts rms. The impedance is rated at 4 ohms (resistive) from 20 to 20,000 Hz, and the system is recommended for use with amplifiers capable of delivering 50 to 300 watts into a 4-ohm load. Its maximum acoustic output on program peaks is rated at 115 dB SPL under typical listening conditions.
The speakers are furnished with an active external equalizer, the KEF Kube 200, designed for use with the Model 105/3's. The Kube 200 should be installed in a low-level signal path such as a tape-recording loop or between a preamplifier and power amplifier. Pushbuttons on its panel can replace the tape-monitoring function (there are tape-in/out jacks on its rear apron) and bypass its equalizing circuits. It has separate low- and high-frequency control knobs, with center detents, and a small, separate power supply. The Kube 200 is 6 inches wide, 8-1/2 inches deep, and 2-1/2 inches high.

The speakers sound great with or without the equalizer. The internal woofers need refoam due to age. The cosmetic condition is excellent, no blemishes. You can audition in my garage before you buy and even bring your amp, source, and cables if you want. I also have the original speaker boxes and packaging. Cash only.
