RCF LF15X401 Very Linear Frequency Response Characteristics

This item is brand-new, factory sealed.

* The LF15X401 is ideal for use in applications where sizable amounts of low frequency, long excursion & low distortion acoustic power is desired * The robust mechanical design & optimised weight of the device make it desirable for use in fixed installation or touring professional loudspeaker systems. * The transducer's low frequency extension, coupled w/its extremely low generation of harmonic distortion, also makes it ideal for use within critical listening applications such as studio monitoring subwoofer systems. 34 1500 * Part Number 11100090 * 4-inch, fiberglass inside/outside copper voice coil * 3000W continuous program power handling * 96.5 dB Sensitivity * 30 Hz – 1.5 kHz Frequency range * Dual Forced Hyperventing System * Dual spider design w/silicon based dampening control * Triple-roll surround & corrugated straight cone geometry * Nominal Diameter: 380 / 15 mm/inch * Rated Impedance: 8 Ohms * Program Power: 3000 W AES * Power handling capacity: 1500 W AES * Sensitivity: 96.5 dB * Frequency Range: 30 Hz to 1500 Hz * Effective Piston Diameter: 340/13.4 mm/inch * Max Excursion Before Damage (peak to peak): 50 / 1.97 mm/inch * Minimum Impedance: 6.3 Ohms * Voice Coil Diameter: 100 / 4 mm/inch * Voice Coil Material: Copper * Voice Coil Winding Depth: 30 / 1.18 mm/inch * Number of layers: 2 * Kind of layer: inside / outside * Top Plate Thickness: 15 / 0.6 mm/inch * Cone Material: No pressed pulp * Cone Design: Straight * Surround Material: Polycotton * Surround Design: Triple roll Thiele/Small Parameters * Resonance frequency: 34 Hz * DC resistance: 5.5 Ohms * Mechanical factor: 7.6 * Electrical factor: 0.30 * Total factor: 0.29 * BL Factor: 26.5 T · m * Effective Moving Mass: 170 g * Equivalent Cas air load: 146 liters * Effettive piston area: 0.091 m² * Max. linear excursion (mathematical): 11.5 mm * Voice - coil inductance at 1kHz: 2,5 mH * Half-space efficiency: 1.90% Mounting information * Overall Diameter: 393 / 15.5 mm/inch * Bolt Circle Diameter: 371-376 / 14.6-14.8 mm/inch * Bolt Hole Diameter: 6.5 / 0.3 mm/inch * Front Mount Baffle Cut-out: 354 / 13.9 mm/inch * Rear Mount Baffle Cut-out: 354 / 13.9 mm/inch * Depth: 145 / 5.7 mm/inch * Volume occupied by the driver: 4.3 / 0.15 liters/ft³ * Net Weight: 12.6 / 27.7 kg/lbs Shipping information * Shipping weight: 13.6 / 29.9 kg/lbs
