The SD15R100 is a highly 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 has a rated bandwidth of 40Hz to 2000Hz. The transducer uses high energy neodymium magnetics to achieve a very high acoustic output to weight ratio. The SD15R100 has been optimized for use in two way or three way sound reinforcement systems.The SD15R100 employs a large format 4 inch 101.6mm diameter voicecoil 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 SD15R100 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 precision round wire technology in an inside/outside geometry to insure very high conversion efficiency.The P Audio circular wire technology & inside/outside winding configuration provides a very large cross-sectional area that substantially improves system cooling & reduces power compression.The system suspension has been designed specifically for high linear displacement & extended low frequency response. The SD15R100 also features a double spider configuration that provides system reliability & mechanical control. The cone suspension is a high excursion rubber based design that is ideal for deep bass applications in band pass enclosures & extended bass vented designs.The transducer chassis is a die cast aluminum design that insures a very high degree of structural integrity.
