JBL Bags PRX Subwoofer Caster Board | PRX915XLF

Designed exclusively for the JBL PRX915XLF powered subwoofer, this caster board delivers reliable mobility for live sound professionals working festivals, corporate events, and touring productions. The contoured plywood base eliminates the improvised solutions that plague mobile rigs, providing a secure platform engineered to match the subwoofer's footprint exactly.

Two-inch hook-and-loop handle straps lock the cabinet to the base, preventing shifts during load-in and venue transitions. Heavy-duty 4-inch swivel casters handle uneven surfaces, loading ramps, and backstage terrain that would defeat smaller wheels. Installation requires no modifications to the subwoofer itself.

This kit solves the recurring challenge of moving powered subs between truck and stage without risking back injury or cabinet damage. Unlike universal dollies that require shimming or leave speakers unsecured, this model provides instant fitment and repeatable protection for production companies running multiple PRX rigs.
