Caratteristiche
☑ 4,5-inch Inside/Outside copper voice coil
☑ 3000 Watt continuous program power handling
☑ 97.5 dB Sensitivity
☑ 30 Hz - 1 kHz Frequency range
☑ Dual-forced air ventilation for minimum power compression
☑ Dual spider designed with silicon based damping control
☑ BL of 30.2 Txm to provide a faster and accurate low frequency
The LF18N451 is a very high power handling and efficiency transducer specially designed to provide powerful and accurate sub-bass frequencies with low distortion and low power compression. Ultra fast time response. The LF18N451 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. Double silicon spider system ensures excellent control during large excursions. A fully optimized T-pole design generates the minimum amount of flux modulation. The dual-forced air venting system provides a very efficient voice coil ventilation to minimize the power compression.
