Speakers "S-90F" contain a mid-frequency head 20GDS-1-16, and "S-100F" - 30GDS-3 with magnetic fluid MAXID, which allows increasing the power of the speaker up to 100 W. The speaker has two smooth playback level controls for midrange and treble. The adjustment limits are from 0 to -6 dB in the ranges of 500 ... 5000 Hz and 5 ... 20 kHz. In the "-6 dB" position, the signal is attenuated by 2 times. The speaker has LED indication of loudspeaker overloads. Main technical characteristics: Passport power 90 and 100 W, respectively. Rated electric power 35 W. The nominal electrical resistance is 8 ohms. The range of reproducible frequencies is 25 ... 25000 Hz. Characteristic sensitivity in the range of 100 ... 8000 Hz at a power of 1 W is not less than 89 dB. Overall dimensions of any speaker - 710x360x285 mm, weight - 23 kg.
