applications

the p audio e12-800ca is a high output low frequency transducer. The e12-800ca is an upgraded design that features many of p audio’s new technologies and performance upgrades. The 12 inch (305mm) 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 operating bandwidth of the e12-800ca is 50hz to 3500hz. The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio.

the e12-800ca employs a medium format 2.5 inch (63.7mm) diameter voice coil that provides an aes rated 200 watts of continuous power handling and a full 800 watts of peak rated power handling when sufficient amplifier headroom is available. The e12-800ca 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 [single]
