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.

5 from 5 Phenomenal performance

Bought two of these RCF woofers for dual 550L LLT subwoofer enclosures tuned @15Hz for home theatre which easily exceeded my expectations. They deliver very powerful, clean, articulate and extremely deep bass without breaking a sweat. Phenomenal woofer!
