About the Extrema
The Sonus Faber Extrema is a two-way, ABR-loaded stand-mounted loudspeaker introduced in 1991. It uses a 28mm soft-dome tweeter, a 190mm mineral-loaded polypropylene-cone woofer, and an Auxiliary Bass Radiator based on a KEF B139 or TDL 3021GT03 bass unit. Its first-order 2kHz crossover uses a 6dB/octave slope. Rated specifications include a frequency response of 35Hz–18kHz ±3dB, 88dB sensitivity at 2.83V, 4-ohm nominal impedance, and up to 200W amplifier power. The cabinet combines black satin lacquer with solid walnut and measures approximately 18.1in H × 10.7in W × 21.7in D; each speaker weighs about 88lb (40kg).
