Overview
The USW-210P compact narrow subwoofer provides robust, extended low frequency response for installed sound applications that require convincing bass impact from a slender, low profile loudspeaker. Its dual-driver configuration permits a narrow form factor that fits into restricted architectural spaces to produce output levels equal to or exceeding systems with single 12-inch (or larger) drivers. Its slanted connector panel enables flush mounting the cabinet against wall surfaces, reducing the required installation depth to 12 inches, including connectors.
The USW-210P is ideal for installations requiring high performance and versatility along with an appealing, discreet aesthetic appearance. The USW-210P integrates easily with Meyer Sound loudspeaker systems, such as CAL™ and ULTRA Series loudspeakers.
The USW-210P has an operating frequency range of 30–140 Hz with a conservatively rated linear peak SPL of 126 dB with crest factor >11.5 dB, measured in half-space at 4 m and referred to 1 m using M-noise3. The long skinny bass reflex cabinet employs the same port design as Meyer Sound’s flagship 1100-LFC low frequency control element for high efficiency and low port distortion.
The cabinet houses a two-channel Class D power amplifier with signal processing including driver protection, and frequency and phase correction.
The Intelligent AC™ power supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.
The optional RMS™ remote monitoring system module provides comprehensive, real-time information about loudspeaker parameters from a Mac® or Windows®-based computer running Compass® control software via the RMServer interface.
Meyer Sound constructs the USW-210P cabinet from premium birch plywood coated with a durable black-textured finish and includes a stamped-steel grille to protect the drivers. Weather protection and custom color finishes for specific cosmetic requirements are available options.
With its versatile shape, the USW-210P can be placed on the ground in a horizontal or vertical position to accommodate installation requirements.
The USW-210P comes standard with M8 mounting points at the top and bottom for use with the optional U-bracket that enables wall or ceiling mounting.
In addition, the USW-210P can be securely mounted in a vertical orientation (connectors at top or bottom) using an optional aluminum base plate.
