P Audio 15 In. 4800 Watts Woofer

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 and performance upgrades. The 15 inch (381mm) diameter piston will produce extremely high sound pressure levels at both low and mid band frequencies and is ideal for high level response in both live sound and 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 and 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 and 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 and reliability but to also increase power compression performance by carefully balancing and directing airflow to critical areas. The voice coil design is a bobbin wound geometry with P Audio’s rectangular wire technology to improve conversion efficiency and provide a large cross-sectional area for superior cooling.

The transducer employs magnetic flux demodulation devices in the structure to increase fidelity and sonic accuracy. The system suspension has been designed specifically for high linear displacement and extended low frequency response. The C15-4800CA also features a double spider configuration that further enhances system reliability and mechanical control. The transducer chassis is a die cast aluminum design that insures a very high degree of structural integrity.
