Specifications Speaker complement:One 8" (203 mm) woofers;Two 1" (25 mm) Convex Diaphragm tweeters
Crossover frequencies: 2 kHz Crossover network: LC quarter-section. Air-core tapped choke and polyester capacitors are used. Three-position control switch (accessible from front) supplied for selection of system acoustic power response, from nominally flat to concert-hall balance slope.
Impedance: 8 Ω nominal (6,5 Ω minimum at any setting of balance switch) Efficiency: better than 0,7% when placed with back against wall.Minimum amplifier power: 30 watts per channel to produce 100 dB sound pressure level in most domestic room environments.
Acoustic power output capability: 0,5 acoustic watt minimum , over full frequency range, with 70 watt peak input.0,25 acoustic watt minimum in lowest octave, with 35 watts input.System resonance frequency: 52 Hz, nominal Effective system Q: 1.0. Low-frequency response -3 dB at 41 Hz, -6 dB at 34,5 Hz, when placed close to center of large wall. Low-frequency output increases when system is placed in typical positions with respect to side wall and floor or ceiling.
Enclosure: Stabilized Radiation Loading sealed acoustic suspension design.Outside dimensions: 11" high by 19⅜" wide by 10" front to back (279 mm by 492 mm by 250 mm). Internal volume: 1,265 cubic inches (20,7 liters).Material: High density particle board veneered with walnut, oiled finish
