Rcf MR8N301 High Efficiency, High Power Midrange Specially Designed To Provide Superior Sound Pressure Level In A Very Compact Size.

This item is brand-new, factory sealed.

Especially designed for horn-loading & line array configurations. * The ideal range of application are mid & mid-low frequencies. * The combination of the 3-in voice coil, the neodymium motor & the heat sink basket design makes this driver the ideal solution for most demanding applications. The total weight is reduced to less than half of a comparable ceramic midrange. * 3-inch, finside/outside copper voice coil * 400W continuous program power handling * 107 dB Sensitivity in horn loaded application * 300 Hz – 3 kHz Frequency range * High BL neodymium design * Unique aluminum sealed basket featuring vented fin heat dissipation design * Calibrated back volume for a perfect time domain transient reproduction General Specifications * Nominal Diameter: 200 / 8 mm/inch * Rated Impedance: 8 Ohms * Program Power: 400 W AES * Power handling capacity: 200 W AES * Sensitivity: 102 dB * Frequency Range: 300 Hz to 3000 Hz * Effective Piston Diameter: 168 / 6.6 mm/inch * Max Excursion Before Damage (peak to peak): 15 / 0.6 mm/inch * Minimum Impedance: 9.8 Ohms * Voice Coil Diameter: 76 / 3 mm/inch * Voice Coil Material: Aluminum * Voice Coil Winding Depth: 11 / 0.4 mm/inch * Number of layers: 2 * Kind of layer: inside / outside * Top Plate Thickness: 8 / 0.3 mm/inch * Cone Material: No pressed pulp * Cone Design: Curved * Surround Material: Polycotton * Surround Design: Triple roll Thiele/Small Parameters * DC resistance: 6.6 Ohms * Mechanical factor: 3.45 * Electrical factor: 0.41 * Total factor: 0.37 * BL Factor: 17.8 T · m * Effective Moving Mass: 10.1 g * Equivalent Cas air load: 1.65 liters * Effettive piston area: 0.021 m² * Max. linear excursion (mathematical): 3.5 mm * Voice - coil inductance at 1kHz: 1.16 mH * Half-space efficiency: 12.8% Mounting information * Overall Diameter: 238 / 9.4 mm/inch * Bolt Circle Diameter: 220 / 8.7 mm/inch * Bolt Hole Diameter: 6.5 / 0.3 mm/inch * Front Mount Baffle Cut-out: 202 / 8.0 mm/inch * Rear Mount Baffle Cut-out: 182 / 7.2 mm/inch * Depth: 101.5 / 4.0 mm/inch * Volume occupied by the driver: 2 / 0.07 liters/ft³ * Net Weight: 3.5 / 7.7 kg/lbs * Shipping weight: 4.0 / 8.8 kg/lbs
