In production between 1984-1996, and bi-wire terminals introduced in1990, KEF was a wonderfully British company making their own drivers with a top-notch team. KEF's 104 model saw various versions and the 104/2 was the final result of the product's evolution. With five drivers, the tweeter is KEF's T33 25mm (1") silk dome with slight horn loading. It was flanked above and below by the B110 100mm (5") doped Bextrene midrange cone in a D'Appolito technique. Bass was produced by a pair of coupled cavity B200 200mm (8") paper cone drivers with their center magnets connected by a metal pole. The midrange/tweeter/midrange panel (weighting about 25 lbs) is completely removable from the woofer cabinet (at nearly 45 lbs) and both loudspeaker cabinets are very rigid. Each midrange is enclosed in its own sealed section to reduce any interaction while the tweeter is press fit to the cabinet via a rear screw. The internal woofers' output exits via a flanged port the same size as the midrange units. Specifications: Sensitivity Level: 92dB. Amplifier Requirements: 25-200W into 4 ohms. Maximum Output: 112dB. Frequency Range: 55Hz - 20kHz (+/- 2dB). Crossover Point: 150Hz, 3kHz. Remarks: a) 2-3 minor dents and some signs of cosmetic wear. b) No original packaging. However, they will be safely packed. |
