Avante Audio AVAC4 Caster Kit Set of 4 Wheels w/Brake For A15S+A18S Subwoofer

The AVAC4 Heavy Duty Casters turn an Avante A15S or A18S subwoofer into something you roll instead of lift. The set of four bolts directly to the bottom of either cabinet, which changes load-in from a two-person carry to one person pushing a sub down a ramp or through a hallway. Precision ball bearings keep movement quiet across concrete, carpet, and stage decking, so repositioning during soundcheck does not announce itself through the PA. Each caster carries a brake, so once the sub is placed it stays placed, even on a raked floor or a stage that moves with the crowd. High-strength materials handle the weight of a loaded 18" cabinet and the frequency of use that comes with a working rental or DJ rig. Installation is straightforward and does not call for special tools or modification to the cabinet. For mobile DJs, rental houses, worship teams, and venue staff who move the same subs several times a week, this is the accessory that saves backs and shortens teardown.
