## Description

Features || 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 Chassis | Applications || The 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 in | Power rating : 1000 \N(aes) | Nominal impedance : 8 OHMS | Sensitivity : 97 dB | Frequency range : 30-500 Hz | Chassis type : Cast aluminum | Magnet type : Ferrite | Magnet weight : 2.85 kg/100.6 oz | Voice coil diameter : 99.3 mm/3.9 in | Coil material : CCA-R | Former material : Glass fiber | Cone material : Paper | Surround material : Cloth | Suspension : Double | X-max : 6.75 mm/0.27 in | Gap depth : 13.9 mm/0.54 in | Voice coil winding width : 25.5 mm/1.0 in | Net Weight : 15.9 kg/35.1 lb | Packing Dimension WxDxH : 505 x 505 x 270 mm | Shipping Weight : 15.9 kg/33.7 lb | Small Signal Parameters || Re : 5.7Q | Fs : 37 Hz | Mms : 185.81 g/6.55 oz | Mmd : 159.23 g/5.62 oz | Qms : 6.33 | Qes : 0.51 | Qts : 0.48 | Vas : 231.72 lt/8.18 ft | Bl : 22.0 Tm | Cms : 9.5e-05 m/N | Rms...6.82 Ns/m | Le (at 1kHz) : 0.64 mH | Sd : 1288 cm2
