COAXIAL CX15G251 Professional Low Frequency Transducer PART NUMBER 11100099 .. .. .. .. .. .. Coax. Features 600 Watt continuous program power handling Mid-Bass 2.5-inch , fibreglass outside aluminium voice coil The CX15G251 is a lightweight coaxial driver with excellent linearity and high efficiency. The CX15G251 radiates a coherent single spherical wave front with perfect dispersion control. The design is powered from a large sized single neodymium ring magnet that provides an extremely high flux density and BL factor. The new hyper-vented aluminium basket and magnetic assembly design provide an excellent heat dissipation and lower power compression. Special air-forced ventilations are provided for voice coil, magnet assembly and basket. A 2,5” voice coil combined a strength fibreglass former and aluminium wire drives the mid-bass cone with high efficiency and a good extension. The 1,7” dome compression driver, loaded to a 60° conical waveguide, provides a clear vocal output and a perfect high frequency extension. 100 dB Sensitivity Applications 50 Hz - 3.5 kHz Frequency range Dual-forced air ventilation for minimum power compression The CX15G251 is the perfect lightweight solution for vocal applications, stage monitoring and compact 2-way reflex enclosures. Triple-roll surround and exponential cone geometry 100 Watt Continuous program power handling HF Ideal in designs where a constant radial directivity pattern is a requirement. is designed for use in compact reflex enclosures and stage monitor. 1.75-inch Diaphragm, 1.0-inch Exit Throat Frequency range: 1200Hz – 20kHz 2-slot, optimised geometry phase plug Kapton diaphragm Aluminium rear cover 12,5 mm 170,4 mm Ø 170 mm Ø 353 mm Ø 388 mm CX15G251 CX12G251 CX15G251 50 20 3500 100 1.000 10.000 20.000 CX15G251 DRIVER General Specifications Nominal diameter Rated impedance Program power Power handling capacity Sensitivity 1W, 1m Frequency range Minimum impedance Voice Coil diameter Voice Coil material Number of layers Diaphragm material Diaphragm design Suspension material Suspension design BL factor Flux density Phase plug design Phase plug material Magnetics 25,4/1,00 8 100 50 105 1200 - 20000 6,5 44,4/1,75 Edgewound Aluminum 1-Outside Kapton Dome Kapton Flat 7,5 1,6 2 slot Composite Ferrite mm / inch ohm Watts Watts dB Hz ohm mm / inch Txm T CX15G251 HORN Thiele - Small Parameters Resonance frequency DC resistance Mechanical factor Electrical factor Total factor BL Factor Effective Moving Mass Equivalent Cas air load Effettive piston area Max. linear excursion (mathematical) 5 Voice - coil inductance @ 1KHz Half-space efficiency 25,4/1,00 60° 1800 Structural Polyurethane Throat Diameter Nominal Coverage (-6dB) Cut-off-Frequency Material 110120 SPL, 1w/1m (dB) 110 100 100 90 90 80 80 70 20 100 1.000 10.000 20.000 Frequency (Hz) Frequency response curve of the loudspeaker maketaken in a hemispherical, free field in a reflex box with an Frequency response curve of the loudspeaker in a hemispherical, free and fieldmounted environment and mounted in ainternal volume 55 litres andinternal tuned atvolume 60Hz, applying a sinusoidal signal of 2.83 the V @8 closedof box with an of 600 litres (21,2 cu.ft) enclosing rearatof1m. the driver. 316 Impedance (ohms) Nominal Diameter Rated Impedance Program Power 1 Power handling capacity 2 Sensitivity 3 Frequency Range Effective Piston Diameter Max Excursion Before Damage (peak to peak) Minimum Impedance Voice Coil Diameter Voice Coil Material Voice Coil Winding Depth Number of layers Top Plate Thickness Cone Material Cone Design Surround Material Surround Design 100 10 380/15 mm/inch 8 ohm 600 Watts 300 Watts 100 dB 50 - 3500 Hz 330/15 mm/inch 30/1,18 mm/inch 6,4 ohm 64/2,52 mm/inch Aluminum 14/0,55 mm/inch 1 8/0,31 mm/inch No pressed pulp Curved Polycotton Triple - roll 4 41 5,2 7,6 0,41 0,39 14,9 70 219 0,086 4,8 0,5 3,50 Hz W 388/15,3 369 - 373,5/14,5 - 14,7 5,5/0,22 355/13,98 358/14,09 161/6,34 3,5/0,12 mm/inch mm/inch mm/inch mm/inch mm/inch mm/inch liters/ft3 7,0/15,43 7,3/16,09 Kg/Lbs Kg/Lbs Txm gr liters m2 mm mH % Mounting Information Overall Diameter Bolt Circle Diameter Bolt Hole Diameter Front Mount Baffle Cut-out Rear Mount Baffle Cut-out Depth Volume occupied by the driver 6 Shipping Information 20 100 1.000 Frequency (Hz) Impedance magnitude curve measured in free air. 10.000 20.000 Net Weight Shipping Weight Notes to Specifications 1 Program Power is defined as 3 dB greater than AES power. - 2 AES standard. - 3 Sensitivity measurement is based on a 500-2,5 kHz pink noise signal with input power of 2.83V @ 8 Ohms. - 4 Thiele-Small parameters are measured after a 2 hour warm up period running the loudspeaker at full power handling capacity. - 5 The maximum linear excursion is calculated as: (Hvc - Hg)/2 + Hg/4 where Hvc is the voice coil depth and Hg the gap depth. - 6 Calculated for front mounting on 18 mm thick board.
