Features

4 - inch, fiberglass inside-outside copper voice coil
2400 Watt continuous program power handling
98 dB Sensitivity
30 Hz - 1 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

Incredibly linear frequency response characteristics,the highest power handling of any comparable 18-inch neodymium transducer, the lowest power compression. The LF18N401 uses a fibre loaded cone assembly along with a high excursion triple roll,constant geometry surround. This combination provides remarkablestrength venting system guarantee a very efficient voice coil ventilation for minimum power compression and higher power handling.
