P-Audio EX12-500S

The P Audio EX12-500S is a high output low frequency transducer. The EX12-500S 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 very low frequencies and is ideal for high level deep bass and sub woofer response in both live sound and recorded music venues. The operating bandwidth of the EX12-500S is 50Hz to 5000Hz.

The transducer uses high energy ferrite magnetics to achieve a very high acoustic output to weight ratio.> The EX12-500S employs a medium format 3 inch (76.2mm) diameter voice coil that provides an AES rated 400 watts and 800 watt of Continuous Program Power Capacity.

The EX12-500S utilizes P Audio’s 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 Audio’s 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
