9059 Woofer 130 mm / 90 W

13 cm (5") woofer with robust polypropylene membrane for very compact subwoofer. Designed for multi-purpose applications due to 2 x 4 ohms double voice-coil, with excellent properties as 8 ohms drivers in series configuration. The enormous membrane displacement for its size as well as the very low resonance frequency allows a considerable sound pressure level, the one does not trust such a small speaker. Possible connections: (1) one voice coil not connected (2) both voice coils in series (3) both voice coils in parallel Technical Data: Rated power 60 W Maximum power 90 W Nominal impedance Z (1) 4 Ohm (2) 8 Ohm (3) 2 Ohm Frequency response fu-6000 Hz (fu: Lower cut-off frequency depending on cabinet) . Mean sound pressure level 78 dB (1 W/1 m) Maximum linear displacement +/-5,8 mm (10% THD) Excursion limit +/-11,5 mm Resonanzfrequenz fs Resonance frequency fs 40 Hz Magnetic induction 0,92 T Magnetic flux 694 µWb Obere Polplattenhöhe Height of front pole-plate 6 mm Voice coil diameter 40 mm Height of winding 12 mm Cutout diameter 123 mm Net weight 1,5 kg D.C. resistance Rdc (1) 3,8 Ohm (2) 7,9 Ohm (3) 2,0 Ohm Mechanical Q factor Qms (1) 4,27 (2) 4,39 (3) 4,59 Electrical Q factor Qes (1) 0,86 (2) 0,41 (3) 0,48 Total Q factor Qts (1) 0,71 (2) 0,37 (3) 0,43 Equivalent volume Vas (1) 5,10 l (2) 5,64 l (3) 5,30 l Effective piston area Sd 94,2 cm² Dynamically moved mass Mms 37 g Force factor Bxl (1) 6,5 Tm (2) 13,2 Tm (3) 6,19 Tm Inductance of the voice coil L (1) 0,77 mH (2) 2,75 mH (3) 0,69 mH Connections 4,8 x 0,8 mm (+) 2,8 x 0,8 mm (-)
