The ProX MB-30 30″ Disco Polyfoam Mirror Ball is built for major venue installations, concert productions, festivals, large nightclubs, and high-end event productions where a statement-size mirror ball anchors the room. At 30 inches across, this ball moves into the large-format category and uses upsized tile and core construction to match its scale.
The ProX MB-30 30″ Disco Polyfoam Mirror Ball is built around a high-density Polystyrene foam (EPS) core engineered specifically for large-format mirror balls. EPS is the professional industry standard for this application thanks to its exceptional strength-to-weight ratio, dimensional stability, and resistance to environmental stress. The closed-cell foam structure resists humidity, will not warp under stage heat, and maintains a true spherical profile across years of touring and venue installation, which is critical at this size where any deviation from round affects rotation balance.
The exterior is fully tiled in precision-cut high-grade glass mirror tiles measuring 20mm (3/4″), scaled up to deliver larger, more dramatic individual reflections across bigger rooms. Each tile features a premium silvered backing for maximum reflectivity, true color rendering, and crisp beam definition, manufactured to consistent thickness with clean square edges for tight uniform placement across the sphere. The mirror coating is sealed against tarnishing to maintain its bright finish through years of professional use. Every tile is bonded with a professional-grade high-strength adhesive that holds securely through continuous rotation, transport vibration, and the demands of professional touring and installation environments. The denser ProX tile pattern produces an exceptionally bright, saturated reflection field that fills large venues with cascading light and color.
Internally, a steel reinforcement rod runs the full top-to-bottom axis of the ball, anchored by a heavy-duty removable O-ring at each pole and secured by an M10 nut for maximum mounting strength. At this size, the steel core and dual O-ring mounting hardware are essential for safe and balanced hanging, providing strong mechanical anchor points designed to support the ball reliably under long runs of motor-driven rotation. The MB-30 is compatible with the ProX X-MBM-3 (1 RPM) mirror ball motor (sold separately), rated for 30″ through 48″ balls.
Only use Mirrorball Motor X-MBM1 (3 RPM) or X-MBM3 (1 RPM) with this product.
