The Electro-Voice Plasma P2 is a new generation of high-power compact subwoofers. It is designed as an ideal system extension for EV's Plasma P1 powered speakers. Its Class-H amplifier requires no fans for quiet operation, low maintenance, and long-term reliability. Coupled with signal processing for linear acoustic response and unobtrusive protection, it delivers the power required for high-level reinforcement. Dynamic linearity is another benefit of amplifiers designed for system integration with large format transducer motors. The patented LPN (Low-Pass-Notch) filter compensates for transient distortion of dynamic signals and allows the Plasma P2 to achieve a higher acoustic output than expected from a compact cabinet. The Plasma P2's applications are for where the highest-quality sound is required: theater, A/V, stage monitoring, sound reinforcement. Key Features: 800W dynamic output power Compact, ergonomic size for easy transportation EVX180B, direct-radiating 18" woofer Built-in crossover LPN filter to compensate for LF transient distortion for full extended bass response Integrated heavy-duty casters Linear response, fail-safe operation Voice coil tracking protection.
