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.
Applications :
The LF18N405 is ideal for use in applications where incredible power handling is required, long excursion and light weight. Specially designed for touring, perfect for high quality professional bass reflex or bandpass enclosure.
Key features :
4,0 - inch Inside/Outside copper voice coil
3000 Watt continuous program power handling
97 dB Sensitivity
25Hz - 1kHz Frequency range
Hypervented magnetic structure for minimum power compression
Triple roll surround and exponential cone geometry
