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. || Features || 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 || Triple-roll surround and corrugated straight cone geometry || Safety agency : CE compliant || SPECIFICATIONS || Nominal Diameter : 15 inch / 381 mm || Rated Impedance : 8 ohm || Program Power (watt) : 1800 W || Power handling capacity : 900 W || Sensitivity : 97.0 dB || Frequency range : 35 - 1500 Hz || Effective piston diameter : 340 mm / 13.39 inch || Max.
