Electro-Voice","The Electro-Voice® Plasma P1 integrates premium EV transducers with high-power, Class-H amplification and signal processing to provide a combination of sonic detail, SPL, and ease of use.","The Electro-Voice® Plasma P1 integrates premium EV transducers with high-power, Class-H amplification and signal processing to provide an outstanding combination of sonic detail, SPL, and ease of use.An EVX155 15-inch, low-frequency transducer uses a Kevlar®-reinforced cone with RMD® driven by a 4-inch voice coil for well-defined transient response, while maintaining articulate vocals at all SPLs. A proprietary ND6 compression driver with a three-inch diaphragm and 1.4-inch exit provides extended, high-frequency response with very low distortion. A Class-H, two-channel amplifier requires no fans for quiet operation, low maintenance, and long-term reliability. Coupled with signal processing for linear acoustic response and unobtrusive protection, the amplifier delivers the power required for high-level reinforcement.Dynamic linearity is another benefit of amplifiers designed for system integration with large-format transducer motors. L-track is embedded into the Plasma P1 to provide convenient, multi-axis suspension and attachment points for an optional suspension arm. The compact, multi-angle enclosure can be used either in monitor position (in left and right configurations) or an array. The Plasma P1 is designed for uniform coverage in both horizontal and vertical planes. It is designed for applications where the highest quality sound is required: theater, A\/V, stage monitoring, and sound reinforcement.
