Acoustic systems "Cleaver 100AS-002" and "Cleaver 100AS-002-1".
Acoustic systems, passive or active, as well as electro-acoustic units, hearing aids, electric megaphones, intercoms ...Passive speaker systemsAcoustic systems "Cleaver 100AS-002" and "Cleaver 100AS-002-1" were produced presumably since 1992. Both speakers are 3-way compression type. The LED power level indicator allows you to visually monitor the power input. The speakers used heads with a maximum rated noise power of 75 W (LF), 20 W (MF) and 6 W (HF). The dome-shaped diaphragm creates low-directional radiation, which increases the area of perception of the stereo effect. The frequency range is divided into sub-bands by complex third-order crossover filters with a slope of the frequency response - 18 dB per octave and crossover frequencies of 800 and 4000 Hz. The systems have a rigid casing, which excludes overtones typical of compression systems from secondary radiation of the walls. The body is made of chipboard. To achieve high tightness, the wall joints are made with glue, and the joints of the heads with the body are sealed with polyurethane foam gaskets. The midrange and tweeter heads are covered with a plywood screen that protects the midrange head from the pressure exerted by the woofer head. To absorb acoustic energy and damp standing waves, the internal volume of the case is filled with a highly efficient sound-absorbing material - super-thin fiberglass. To reduce the diffraction effect and tunnel resonances, the heads are flush with the outer surface of the front wall. In the AC "Cleaver 100AC-002" the front wall is covered with a removable decorative panel. The systems have a well-balanced soft sound with deep and clean lows and transparent mids and highs. The minimum value of the total electrical resistance is not less than 3.2 ohms. The level of characteristic sensitivity in the frequency range 100 ... 8000 Hz is 85.5 dB. Total characteristic harmonic distortion at an average sound pressure level in the frequency range 100 ... 8000 Hz, equal to 90 dB, measured in the frequency ranges, Hz: from 250 to 1000 - 1.5%, over 1000 to 2000 - 1.5% , over 2000 to 6300 - 1%. The frequency range is not more than 40 ... 25000 Hz. The difference in the frequency characteristics of the sound pressure of systems of the same type, averaged in octave frequency bands in the range of 250 ... 8000 Hz, is not more than 2 dB. Maximum long-term power 100 W, short-term power 150 W. Maximum noise power 75 W. Dimensions of the AC "Cleaver 100AS-002" (Cleaver 100AS-002-1) - 396x362x714 (340x362x684) mm. Speaker weight - 32 kg.
