The SK-F loudspeaker system is a fully horn loaded compact cabinet made for applications where directivity and power are of importance. The SK-F system is a processor controlled 3way design, with 2way active LO & MID/HI. The MID & HI sections use a sophisticated built-in passive crossover. The patent pending 3waydesign allows better performance in terms of power handling and distortion: using an 1” high frequency driver means having less distortion above 2kHz in comparison to a conventional 2” driver because of diaphragm resonance. The three drivers share the same horn, acoustically aligned at the same vertical plane producing thus an astonishing flat and smooth frequency response from 60Hz to 20kHz.

(1) Frequency response: +/- 3dB, measured at 3 meters, on axis, half-space conditions -  MLSSA 1/3 octave

(2) Max peak SPL: Measured with music referred to 1 meter

(3) Crossover: Acoustical crossover frequency - at these frequency, transducers produce equal sound pressure level

(4) AES: Power handling is measured under AES standard conditions

(5) Power AMPS: Amplifier RMS output power per channel into 2 ohms, both channel driven
