HP 46CM 8 OHMS 1000W RMS 97 dB 25-1000 Hz RCF

Haut-parleur 46cm - 1000 W rms LF18N405 WOOFER 4,0 - inch Inside/Outside copper voice coil 3000 Watt continuous program power handling 97.5 dB Sensitivity 25Hz - 1kHz Frequency range 4,0 - inch Inside/Outside copper voice coil 3000 Watt continuous program power handling 97.5 dB Sensitivity 25Hz - 1kHz Frequency range Hypervented magnetic structure for minimum power compression Triple roll surround and exponential cone geometry The LF18N405 is an extended low frequency with high power handling , designed to provide powerful and accurate bass frequencies with low distortion, low power compression and very high SPL. The LF18N405 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. The single spider system is specifically designed with a heavy cloth which ensures excellent control during large excursions. A fully optimised T-pole design generates the minimum amount of flux modulation. The Dual-forced air venting magnetic structure system provides a very efficient voice coil ventilation to minimize the power compression.
