P-Audio's 15BM-300B is designed as a high-power bass-mid driver for use in two and three way systems. In addition to being able to handle a continuous power of 300W AES, the 15BM-300B has an exceptionally wide useable frequency range, from 45Hz up to 3500Hz.
The P Audio 15BM-300B is a high output wide bandwidth transducer. The 15BM-300B 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 has a rated bandwidth of 45Hz to 3500Hz. The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio. The 15BM-300B has been optimised for use in two way or three way sound reinforcement systems.
The 15BM-300B employs a medium format 3 inch (76.2mm) diameter voice coil that provides an AES rated 300 watts of continuous power handling and a full 1200 watts of peak rated power handling when sufficient amplifier headroom is available. The 15BM-300B 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 precision circular wire technology to ensure high conversion efficiency. The system suspension has been designed specifically for high linear displacement and extended low frequency response. The 15BM-300B also features a single spider configuration that provides system reliability and mechanical control. The transducer chassis is a die cast aluminium design that ensures a very high degree of structural integrity.
