Overview

The USW-112P compact narrow subwoofer provides big bass sound for very tight spaces. Its compact rectangular enclosure and slanted connector panel enable flush-mounting of the cabinet against wall surfaces, reducing required installation depth to 12 inches, including connectors.

Designed to be the ideal companion to Meyer Sound’s ULTRA-X20, it also complements the low frequencies in other Meyer Sound loudspeakers, such as the UP-4slim and those in the UPM family.

The USW-112P has an operating frequency range of 35–140 Hz with a linear peak SPL of 123 dB, measured in half-space at 4 m and referred to 1 m using M-noise. The bass reflex cabinet employs a low-velocity port design for high efficiency and low port distortion.

The cabinet houses an open-loop, Class-D power amplifier with signal processing including correction filters for phase and frequency response, and driver protection circuitry. The amplifier/ processing package incorporates Meyer Sound’s Intelligent AC™, which auto-selects the correct operating voltage, suppresses high voltage transients, filters EMI and provides soft-start power-up.

Audio connectors are XLR (analog version) or etherCON TOP (Milan™ Certified digital version1), and power input and looping output connectors are PowerCON 20 (analog version) or powerCON TRUE1 TOP (digital and weather-protected models).

Remote monitoring is possible on the analog version via the optional RMS remote monitoring module, which in conjunction with the optional RMServer™ hardware unit, provides comprehensive monitoring of loudspeaker parameters from a host computer running Compass® Control Software. The digital version provides integrated monitoring via Compass Control Software.

Meyer Sound builds the USW-112P cabinet from premium birch plywood coated with a slightly textured black finish and includes a powder-coated, round-perforated steel grille to protect the drivers.

With its versatile shape, the USW-112P can be placed on the ground in either horizontal or vertical positions to accommodate installation requirements.

The USW-112P comes standard with M8 mounting points at the top and bottom for use with the optional U-bracket that enables wall, ceiling, or truss mounting. It also features an integral 35 mm pole mount receptacle with M20 threads for added stability.

Weather protection and custom color finishes for specific cosmetic requirements are available options.
