The latest arrival from Meyer Sound is here — the USW-121P, a compact powerhouse that brings real low-end authority to spaces where large subs simply don’t fit. Designed to deliver deep, controlled bass with effortless musicality, it’s a perfect match for theatres, corporate AV, touring rigs, and immersive installations where clarity and control are non-negotiable.
Despite housing a single 21-inch long-excursion driver, the USW-121P remains discreet, standing just 622 mm deep. It’s built for tight footprints: tucked into or just in front of the stage, discreetly integrated into scenic or architectural layouts without compromise. Thanks to its unique angled rear design, the USW-121P can even be placed flat against a wall while keeping all connections and cooling clear — ideal for stages, cinemas, and corporate spaces where every centimetre counts. The result? True Meyer low-frequency extension, reaching down to 20 Hz, from a box that disappears into the background.
USW-121P packs Meyer’s new GEN-1 processing platform, offering Galileo-class DSP, Nebra control, and AES67 network audio — all built in. That means faster setup, direct integration with MAPP 3D system design, and the option to run fully networked Meyer ecosystems without additional processors. Future-ready with Milan capability, it’s as smart as it is strong.
The design focus is simple: exceptional bass where it counts. Expect tight, musical punch rather than overwhelming boom — a sub that extends your system’s range without muddying the mix. It’s this control that makes it ideal across performance environments:
Theatre: Tucked neatly into or just in front of the stage, the USW-121P adds depth and drama to music, effects and soundscapes while keeping sightlines clear. Paired with ULTRA-X40 or ULTRA-X80 Left/Right, it forms a beautifully balanced system that delivers vocal clarity and full-range power without drawing attention to itself.
Corporate & AV: When visual footprint matters as much as sonic impact, this sub disappears into conference stages, presentation spaces and exhibition stands while providing weight and presence for playback and voice-of-god moments. With built-in DSP and Nebra control, setup is quick and consistent — perfect for touring corporate shows and multi-venue events.
Live Events & Touring: Rugged, efficient and network-ready, the USW-121P thrives on the road. Whether it’s ground-stacked beneath ULTRA-X loudspeakers or supporting a flown 2100-LFC system, it adds that crucial layer of punch for audiences who expect to feel the show as much as hear it.
Install & Immersive: In museums, houses of worship, or immersive environments, the USW-121P delivers low-frequency presence without vibration or vent noise. It slots easily into architectural layouts and can be weatherised for outdoor applications.
Every detail is designed for real-world practicality — from the angled rear corner that allows wall placement while keeping connectors accessible, to the low-velocity square port that minimises turbulence at high SPLs. Power is via powerCON TRUE1 TOP, and the cabinet is available in standard or weather-protected finishes, including IP55 outdoor-rated OT versions.
In short, the USW-121P is a subwoofer that thinks beyond size. It’s a true Meyer Sound solution: compact, precise, intelligent, and powerful enough to anchor modern sound systems across theatre, corporate and live event sectors.
