High power 15-in woofer.

High power 15-in woofer.Very good power handling, excellent linearity & 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-in ch, fiberglass inside/outside copper voice coil1000W continuous program power handling98 dB Sensitivity40 Hz - 2 kHz Frequency rangeDual spider design w/silicon based dampening controlM-roll surround & 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 & 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 at 1kHz: 1.5 mH Half-space efficiency: 2.94% 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
