Product Overview
The Meyer Sound USW-112XP/WP is a weather-protected IntelligentDC 1x12" compact narrow subwoofer that delivers low-frequency reinforcement to covered outdoor and semi-exposed installed sound systems while drawing both DC power and balanced audio over a single cable. Rated IP54 with the rain hood installed, this externally powered model is the ideal low-frequency companion to the ULTRA-X20XP and is suited to houses of worship, outdoor commercial AV systems, and architectural installs requiring conduit-free, low-voltage distribution.
Product Description

The USW-112XP/WP houses an open-loop Class D power amplifier rated at 600 W peak with onboard correction filters for phase and frequency response and driver protection. With IntelligentDC technology, it receives 48 V DC power and balanced audio from a single Phoenix 5-pin connector fed by a Meyer Sound MPS IntelligentDC power supply (MPS-482HP or MPS-488HP required), eliminating wiring conduits while preserving the advantages of self-powered systems. Its compact rectangular enclosure and slanted connector panel allow flush wall mounting at only 12 inches of depth including connectors, and the bass-reflex cabinet uses a low-velocity port based on the USW-210P design for high efficiency and low port distortion. For an AC-powered configuration, compare the USW-112P, and browse the full Meyer Sound collection at Creation Networks.
