This self-powered subwoofer provides flat response in the 32-to-180 Hz range. It 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 cabinet houses two 15″ drivers, each powered by a dedicated channel of the proprietary built-in class AB/bridged amplifier (350 watts per channel) with complementary power MOSFET output stages. Each channel features a protection limiter that prevents driver over-excursion and regulates voice coil temperature, allowing high output levels across the drivers’ entire frequency range.

The USW-1P 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. It also incorporates an Intelligent AC power supply, which auto-selects the correct operating voltage for international use, suppresses voltage transients, and provides soft-start power-up.

The USW-1P is compatible with Meyer Sound’s RMS remote monitoring system. On a Windows-based PC, RMS displays signal and power levels, limiter activity and amplifier temperature for all loudspeakers in the network.
