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 sysetm ensures excellent control during large excursions. A fully optimazed T-pole design generate the minimum amount of flux modulation.
The Dual-forced air venting system provides a very efficient voice coil ventilation to minimize the power compression
