  1. Добрый вечер. Достались два динамика Visaton W200 4ohm. Можно ли сделать на них сабвуфер? Rated power 50 W Maximum power 80 W Nominal impedance Z 4 Ohm Frequency response fu–8000 Hz (fu: Lower cut-off frequency depending on cabinet) . Mean sound pressure level 88 dB (1 W/1 m) Opening angle (-6 dB) 49°/4000 Hz Excursion limit +/−10 mm Resonance frequency fs 45 Hz Magnetic induction 1.0 T Magnetic flux 400 µWb Height of front pole-plate 5 mm Voice coil diameter 25 mm Height of winding 9 mm Cutout diameter 185 mm Net weight 1.045 kg D.C. resistance Rdc 3.2 Ohm Mechanical Q factor Qms 3.46 Electrical Q factor Qes 0.77 Total Q factor Qts 0.63 Equivalent volume Vas 54 Effective piston area Sd 207 cm² Dynamically moved mass Mms 14 g Force factor Bxl 4.2 Tm Inductance of the voice coil L 0.5 mH
