High Output 18 Inch Precision Transducer w/3.9-in Large Format Voice Coil - 8 Ohms

3.9'' Large Format Voice Coil 4000 Watts Peak Power Handling Active Balanced Cooling Integrated Demodulation Rings Double Spider Design Ferrite Magnetics Precision Rectangular Ribbon Wire Geometry Die Cast Aluminum ChassisApplicationsThe P Audio P180-4000CA is a high output low frequency transducer designed w/a vintage voicing. The P180-4000CA is an upgraded design that features many of P Audio s new technologies & performance upgrades. The 18 inch 457mm diameter piston will produce extremely high sound pressure levels at very low frequencies & is ideal for high level deep bass & sub woofer response in both live sound & recorded music venues. The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio.The P180-4000CA employs a large 3.9 inch 99.3mm diameter voice coil & has been upgraded to an AES rated 1000 watts of continuous power handling & a full 4000 watts of peak rated power handling when sufficient amplifier headroom is available. The P180-4000CA utilizes P Audio s Auto Balanced Cooling ABC technology to not only improve transducer power handling & reliability but to also increase power compression performance by carefully balancing & directing airflow to critical areas.The voice coil design is a bobbin wound geometry w/P Audio's rectangular wire technology to improve conversion efficiency & provide a large cross-sectional area for superior cooling.The transducer employs magnetic flux demodulation devices in the structure to increase fidelity & sonic accuracy. The system suspension has been designed specifically for high linear displacement & extended low frequency response. The double spider design further enhances system mechanical control & reliability.The transducer chassis is a die cast aluminum design that insures a very high degree of structural integrity.Nominal diameter..457 mm/18 inPower rating..1000 NaesNominal impedance..8 OHMSSensitivity...97 dBFrequency range..30-500 HzChassis type..Cast aluminumMagnet type...FerriteMagnet weight..2.85 kg/100.6 ozVoice coil diameter..99.3 mm/3.9 inCoil material...CCA-RFormer material..Glass fiberCone material...PaperSurround material..ClothSuspension...DoubleX-max..6.75 mm/0.27 inGap depth..13.9 mm/0.54 inVoice coil winding width..25.5 mm/1.0 inNet Weight..15.9 kg/35.1 lbPacking Dimension WxDxH.505 x 505 x 270 mmShipping Weight..15.9 kg/33.7 lbSmall Signal ParametersRe...5.7QFs...37 HzMms..185.81 g/6.55
