Description
RCF LF18N451 18" Power: 1500W rms, 3000W prog. Sensitivity: 97,5 Freq. Range 30-1000 Hz
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 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
