Overview4-inch, fiberglass inside/outside copper voice coil 1800W continuous program power handling 97 dB Sensitivity 35 Hz – 1.5 kHz Frequency range Dual-forced air ventilation and 15mm top plate for minimum power compression Dual spider design with silicon based dampening control Triple-roll surround and corrugated straight cone geometry Specifications
Incredibly linear frequency response characteristics, the highest power handling of any comparable 15-inch neodymium transducer,the lower power compression. The LF15N401 uses a fibre loaded cone assembly along with a high excursion triple roll,constant geometry surround. This combination provides remarkable strength and a peak to peak maximum excursion of 52mm. The unique Dual-forced air venting system guarantee a very efficient voice coil ventilation for minimum power compression and higher power handling.
