The P Audio E15-600S is a very high output low frequency transducer. The E15-600S is an upgraded design that features many of P Audios new technologies and performance upgrades. The 15 inch (381mm) diameter piston will produce extremely high sound pressure levels at low frequencies and is ideal for high level full range response in both live sound and recorded music venues. The E15-600S is an excellent choice as a low frequency component in a professi onal two way system design. The operating bandwidth of the E15-600S is 40Hz to 2000Hz. The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio. The E15-600S employs a large format 3.9 inch (99.3mm) diameter voice coil that provides an AES rated 600 watts of continuous power handling and a full 2400 watts of peak rated power handling when sufficient amplifier headroom is available. The large voice coil diameter and very high power handling make this transducer and excellent choice for ultra high performance professional sound reinforcement systems. The E15-600S utilizes P Audios under damper venting technology to improve transducer air flow and reduce turbulence under the damper and around the voice coil. The voice coil design is a bobbin wound geometry with P Audios precision round wire technology to maximize system conversion efficiency. The suspension has been designed specifically for high linear displacement and extended low frequency response. The transducer chassis is a heavy gauge stamped steel design that insures a very high degree of structural integrity.
