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. A EVX155 15" LF transducer uses a Kevlar®-reinforced cone with RMD® driven by a 4" voice coil for well-defined transient response, while maintaining articulate vocals at all SPLs. A proprietary ND6 compression driver with a 3" diaphragm and 1.4" exit provides extended HF 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 very compact multi-angle enclosure can be used either in monitor position (in left and right configurations) or arrayed. The Plasma P1 is acoustically designed for uniform coverage in both horizontal and vertical planes adding to its versatility. The P1’s applications are for where the highest quality sound is required: theater, A/V, stage monitoring, and sound reinforcement.
