RCF LN19S400

19-inch neodymium low frequency driver rated at 3000W program power with 8 ohm impedance and 98.5 dB sensitivity, covering a 25 Hz to 1000 Hz frequency range. Uses an ultralight CCAW 4-inch, 4-layer inside-outside voice coil on a fiberglass former with a BL factor of 32 T/m and an aluminum demodulation ring to reduce distortion. Fiber-loaded cone with triple-roll polycotton surround allows 65mm peak-to-peak excursion. Hyper-Vented dual-forced air cooling reduces power compression. Weighs 10.2 kg.
