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.

4-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
