A self-powered subwoofer loudspeaker that provides a flat low-frequency response, the Meyer USW-1P performs well with UPA-P Series self-powered loudspeakers to form full-range reproduction systems, and is also compatible with other Meyer Sound self-powered mid-high loudspeakers.
The Meyer USW-1P compact cabinet satisfies a broad range of installation requirements, housing two 15-inch drivers, each powered by a dedicated channel with a protection limiter which allows high output levels across the drivers' entire frequency range. In addition, the input incorporates a built-in crossover and accepts a full-range signal, allowing for simple daisy-chain signal distribution and eliminating the need for external crossovers.
Applications include theatrical sound reinforcement, surround sound presentations, houses of worship, and portable and installed audio-visual systems.
