RCF LF15N451

Reproduktor 15", 1300W, 97dB, 35-1500Hz, X-max 8,7mm, hmotnost 11,38kg

The LF15N451 is a very high power handling woofer , specially designed to provide powerful and accurate bass frequencies with low distortion and low power compression. Ultra fast time response. The LF15N451 uses a fibre loaded cone assembly along a large triple roll surround, this combination provides remarkable strength and control. Double silicon spider system ensures excellent control during large excursions. A fully optimised T-pole design generate the minimum amount of flux modulation to get lower distortion.

The transducer design is based on a very strong neodymium magnetic structure and a new 4,5” inside-outside copper coil, this combination guarantees higher handling especially in comparison to standard 4" voice coil designs. The unique Dual-forced air venting system provides a very efficient voice coil ventilation to minimize the power compression.
