Outline STADIA 28 Constant Curvature Array Enclosure

The Outline STADIA 28 brings the acclaimed STADIA series performance to smaller outdoor venues, theme parks and public spaces. Weighing just 21 kg yet capable of a thunderous 139 dB peak SPL, this compact constant-curvature array module delivers exceptional speech intelligibility and musical impact while withstanding demanding weather conditions.
Engineered for Clarity & Coverage

Two 8″ neodymium mid-woofers work in tandem with a 3″ compression driver on a proprietary waveguide to create a precise 90° × 22.5° dispersion pattern. Combine up to six cabinets vertically or horizontally for seamless 135° coverage, ensuring every seat and concourse is immersed in high-definition sound.
Built to Endure the Elements

Outline’s IP55-rated ‘OutSIDE’ elastoplastic coating chemically bonds with the Baltic birch enclosure, providing long-term protection against water, UV and temperature extremes. A powder-coated steel grille and corrosion-resistant M10 rigging hardware preserve structural integrity in permanent outdoor installs.
Fast, Flexible Integration

The unobtrusive suspension system and multiple M10 points allow rapid vertical or horizontal deployment, while bi-amping simplifies amplifier channel management and maximises headroom. Barrier strip connectors ensure secure, weather-sealed wiring in professional installations.
