Acoustic systems 'Electronics 25AS-227' and 'Amfiton 25AS-227'.
Acoustic systems, passive or active, as well as electro-acoustic units, hearing aids, electric megaphones, intercoms ...Passive speaker systemsAcoustic systems "Elektronika 25AS-227" and "Amfiton 25AS-227" since 1984 have been produced by the Leningrad plant Ferropribor and Lvov PO named after Lenin. Three-way speaker systems with phase inverter "Electronics 25AS-227" and "Amfiton 25AS-227" are similar, made in mirror reflection and are intended for high-quality reproduction of phonograms as part of a complex of amplifying equipment of the highest group of complexity. The LF functions are performed by the 25GD-42 head, the MF 15GD-11 head, and the HF isodynamic head 10GI-1. The magnetic system of the head consists of 2 parallel rows of magnets, and the flat membrane is made of a polymer film on which a voice coil is applied. It provides a non-inertial radiation mode, which has expanded the frequency range to 31.5 kHz, and reduced nonlinear and phase distortions. The speakers are made in pressed chipboard bodies, pasted over with a thin film imitating valuable breeds. Rated input power 25 W. Resistance 4 ohms. The operating frequency range is 31.5 ... 31500 Hz. Average sound pressure 1.2 Pa. Speaker dimensions - 320x600x320 mm. Weight 25 kg. The price of one speaker is 145 rubles. Since 1986, AS has been referred to as "Electronics 25AS-027" and "Amfiton 25AS-027".
