Rcf L15P540 15" 400w Woofer

High power 15-in woofer. Very good power handling, excellent linearity and very low distortion. Very efficient heat dissipation in ensured by a radiator that is part of the basket design. The air is forced in the radiator thanks to a dual sealed spider design. 3-inch, fiberglass inside/outside copper voice coil 1000W continuous program power handling 98 dB Sensitivity 40 Hz 2 kHz Frequency range Dual spider design with silicon based dampening control M-roll surround and exponential cone geometry * The excellent linear response, well controlled down to 40 Hertz, makes the L15P540 especially suitable for horn-loaded applications, band-pass enclousuresband small size bass reflex systems. * It is a very good solution for two or three way system when a very high BL and maximum punch is required. * 380 / 15 mm/inch * Rated Impedance: 8 Ohms * Program Power: 1000 W AES * Power handling capacity: 500 W AES * Sensitivity: 98 dB * Frequency Range: 40 Hz to 2000 Hz * Effective Piston Diameter: 330 / 13 mm/inch * Max Excursion Before Damage (peak to peak): 36 / 1.4 mm/inch * Minimum Impedance: 6.8 O * Voice Coil Diameter: 76 / 3 mm/inch * Voice Coil Material: Copper * Voice Coil Winding Depth: 18 / 0.7 mm/inch * Number of layers: 2 * Kind of layer: inside / outside * Top Plate Thickness: 10 / 0.4 mm/inch * Cone Material: No pressed pulp * Cone Design: Curved * Surround Material: Polycotton * Surround Design: M - roll * THIELE/SMALL PARAMETERS * Resonance frequency: 50 Hz * DC resistance: 5.6O * Mechanical factor: 9.7 * Electrical factor: 0.41 * Total factor: 0.39 * BL Factor: 21.4 T - m * Effective Moving Mass: 106 g * Equivalent Cas air load: 100 liters * Effettive piston area: 0.085 m-Squared * Max. linear excursion (mathematical): 6.5 mm * Voice - coil inductance @ 1kHz: 1.5 mH * Half-space efficiency: 2.94% * MOUNTING INFORMATION * Overall Diameter: 387 / 15.2 mm/inch * Bolt Circle Diameter: 371 / 14.6 mm/inch * Bolt Hole Diameter: 6.5 / 0.3 mm/inch * Front Mount Baffle Cut-out: 352 / 13.9 mm/inch * Rear Mount Baffle Cut-out: 360 / 14.1 mm/inch * Depth: 163 / 6.4 mm/inch * Volume occupied by the driver: 3.8 / 0.13 liters/ft Cubed * Net Weight: 9.5 / 20.9 kg/lbs * SHIPPING INFORMATION * Shipping weight: 10 / 22.0 kg/lbs
