Mackie CK100 Caster Kit for DRM18S and DRM18S-P 18-Inch Subwoofer

Mackie CK100: Roll Your 18-Inch Subwoofer Into Place

The Mackie CK100 is a four-caster kit that bolts to the bottom of the DRM18S and DRM18S-P 18-inch powered and passive subwoofers, turning a heavy floor cabinet into a rolling piece of gear. It ships with everything needed for the conversion - four swivel casters and a full set of M6 mounting hardware - so a sub that once took two people to lift into position can be wheeled there by one. For the engineer who moves an 18-inch subwoofer every gig, it is the small upgrade that saves a back.

A Bolt-On Fit for the DRM18S

The CK100 is engineered specifically for the DRM18S platform, aligning to the threaded inserts molded into the subwoofer's bottom panel so the casters sit flush and secure. Because it uses the cabinet's existing mounting points, installation adds no drilling and no modification - the plate-mounted casters simply bolt straight on, keeping the sub's structural integrity and hardware intact.

Everything for the Install in the Box

Inside the kit are four swivel casters plus sixteen M6 hex-head screws, sixteen locking washers, and sixteen flat washers - the complete hardware set to mount all four wheels. An M6 hex wrench is the only tool required, and the whole conversion takes just a few minutes, letting you get the subwoofer rolling before the rest of the rig is even off the truck.

Who the CK100 Is For

Mobile DJs, touring engineers, houses of worship, and rental companies that deploy the DRM18S rely on the CK100 to speed load-in and load-out. If your 18-inch subwoofer spends its life moving between the truck, the stage, and storage, these casters are the purpose-built way to make it roll instead of carry.
