Introducing the ProX MB-36 36" Mirror Disco Ball , a large-format professional reflective sphere built for arena productions, major concert venues, flagship nightclub installations, and festival main stages where the mirror ball has to be visible and impactful across an enormous room. At 36 inches across, the ProX MB-36 is not just a fixture in the rig. At this size, it becomes a visual anchor for the entire space, generating a sweeping, immersive reflection field that fills every corner of a large venue with cascading light and color. For event producers, lighting designers, and venue operators who invest in building a serious environment, the MB-36 is the ball that delivers. Core Construction The MB-36 is built around a high-density Polystyrene foam (EPS) core engineered specifically for large-format mirror ball construction. EPS provides the exceptional strength-to-weight ratio and long-term dimensional stability that a ball of this size demands. The closed-cell foam structure resists humidity, will not warp or deform under sustained stage heat, and holds a precisely true spherical profile across years of touring, rigging, and permanent venue installation. At 36 inches, maintaining an accurate round profile is critical for balanced motor rotation and even light distribution across the sphere from every angle. Glass Mirror Tiles The full exterior of the MB-36 is covered in precision-cut, high-grade glass mirror tiles measuring 3/4" (20mm) , scaled to match the large format of this ball and to deliver bold, dramatic individual reflections with strong visual presence across big rooms. Each tile is produced to consistent thickness with clean square edges for tight, uniform edge-to-edge placement across the sphere. Every tile carries a premium silvered backing for maximum reflectivity, true color rendering, and crisp beam definition when lit by a focused source. The mirror coating is sealed against tarnishing and discoloration, holding its bright silver finish through years of professional production use. Tile Adhesion and Density Each tile is individually bonded using a premium high-strength industrial adhesive engineered to hold tiles firmly through continuous motor rotation, transport vibration, and the demands of professional touring and venue environments. ProX mirror balls use a denser tile pattern than traditional mirror balls of the same diameter, producing a more saturated, brilliant field of reflected light and color that covers the room more completely with every revolution. Mounting Hardware A reinforced steel center rod runs the full vertical axis of the ball from top to bottom, anchored at each end by a heavy-duty removable O-ring and secured by an M10 nut for maximum mounting integrity. At this size and weight, the internal steel core and dual mounting hardware are essential structural elements, providing the mechanical strength needed for safe overhead rigging and reliable motor connection across long production runs. Motor Compatibility The MB-36 is designed to pair with the ProX X-MBM-3 (1 RPM) mirror ball motor , rated for balls from 30" through 48" and available separately through ProX Direct. Compliance and Weight The MB-36 is CE and RoHS compliant. Net weight is 13.6 kg (30 lbs). Due to its size and weight, the MB-36 ships via LTL freight. Designed by Professionals. Built for Performers.
