| 18", 1500W RMS, 3000W program, 4.5" coil |
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. |
