MID-BASSL12P110KProfessional Low Frequency TransducerVery high efficiency and low distortion are special features of this mid-basstransducer. Special treatments are applied to cone surface and surround foroptimum dampening.PART NUMBER 11146001Features4-inch, fibreglass inside-outside copper voice coil1000 Watt continuous program power handling101 dB Sensitivity60 Hz - 2 kHz Frequency rangeApplicationsThe L12P110K is specially designed for compact size bass reflex enclosures.The unique combination of short voice coil and very high BL/Re ratio makes theL12P100K a very good choice when fast and precise mid-bass reproduction isrequired.Very good for high power horn loaded applications.M-roll damped surroundCorrugated straight damped cone6020005020 100 1.000 10.000 20.000
