Combining advanced loudspeaker technology with equally advanced power capabilities, the Meyer Sound USW-1P self-powered subwoofer provides flat, low-frequency response from 35 Hz to 180 Hz. The Meyer Sound USW-1P performs seamlessly within a fullrange system, in conjunction with UPA-1P, UPA-2P and UPJ-1P loudspeakers. The USW-1P is also fully compatible with other Meyer Sound self-powered loudspeakers.

The Meyer Sound USW-1P cabinet houses two 15-inch drivers, each powered by a dedicated channel of the proprietary built-in class AB/bridged power amplifier (550 watts total peak power) with complementary MOSFET output stages. Each channel incorporates a limiter that prevents driver over-excursion and regulates the voice coil temperature. A smooth limiting characteristic effectively protects the drivers without the compression effects imposed by typical limiters, allowing high output levels across the drivers’ entire frequency range.

Integrating a built-in low-pass crossover while accepting a full-range signal, the USW-1P’s input allows for simple daisychain signal distribution and eliminates the need for external crossovers. Field-replaceable audio input modules accommodate a range of applications. The standard version offers looping XLR input and output connectors, while an enhanced looping version adds polarity switching (the looping output is not affected) and input attenuation (0 dB to -18 dB). A summing mono version with two inputs is also available.

The amplifier/processing package, also field-replaceable, incorporates Meyer Sound’s Intelligent AC™ system, which performs automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Intelligent AC allows failsafe operation worldwide, with no need to manually select the AC mains voltage.

The Meyer Sound USW-1P’s durable enclosure is constructed from premium birch plywood and is covered with a black textured hard-shell finish. A hex-stamped steel grille and a charcoal grey foam cover are included. Standard rigging points are three ring and stud pan fittings (on top) with a load rating of 420 lbs (190.51 kg) per fitting, based on a 5:1 safety factor. (3/8"-16 and M10 metric nut plates are also available.) The cabinet’s rectangular shape makes groundstacking on the floor or stage a simple and stable option. Options available include weather protection and finishes in custom colors for applications requiring specific cosmetics.

The Meyer Sound USW-1P is compatible with the RMS™ remote monitoring system, which offers comprehensive monitoring of system parameters on a Windows®-based network.
