P-Audio C154800CA A- A-B Box 15 Inch Woofer High OutputPrecision Transducer 1200 Wrms 4800 Watts Peak with 3.9-in Large Format Voice Coil 8 Ohms

Features || * 3.9" Large FormatVoice Coil * 4800 Watts Peak Power Handling * Active Balanced Cooling * Ferrite Magnetics * Precision Rectangular Ribbon Wire * Double Spider Suspension * Integrated Demodulation Rings * Die Cast Aluminum Chassis || Applications || The P Audio C15-4800CA is a high output wide bandwidth transducer. The C15-4800CA is an upgraded design that features many of P Audio's new technologies & performance upgrades. The 15 inch (381mm) diameter piston will produce extremely high sound pressure levels at both low & mid band frequencies & is ideal for high level 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 C15-4800CA has been optimized for use in two way or three way sound reinforcement systems & has a rated operating range of 55Hz to 2000Hz. The C15-4800CA employs a large 3.9 inch (99.3mm) diameter voice coil that provides an AES rated 1200 watts of continuous power handling & a full 4800 watts of peak rated power handling when sufficient amplifier headroom is available. The C15-4800CA 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 C15-4800CA also features a double spider configuration that further enhances system reliability & mechanical control. The transducer chassis is a die cast aluminum design that insures a very high degree of structural integrity.
