The Mackie MCK-2035618 CK100 is a caster kit specifically designed to add mobility to compatible Mackie subwoofers, such as the DRM18S active and passive models. This kit provides a set of heavy-duty, swiveling casters that allow users to easily roll the subwoofer across floors, transforming a bulky, heavy cabinet into a maneuverable piece of equipment. This is particularly valuable for mobile DJs, touring sound companies, and installation technicians who need to frequently position and reposition subwoofers in various venues. The casters are engineered to support the substantial weight of the subwoofer while offering smooth rolling over typical indoor surfaces like concrete, wood, or carpet. The kit typically includes all necessary hardware for a secure installation, ensuring that the casters are firmly attached to the subwoofer's reinforced bottom panel.

Installation is straightforward, usually requiring the subwoofer to be placed on its side so that the caster plates can be bolted into pre-drilled mounting points or the cabinet's integral rigging inserts. The casters often feature a locking mechanism on two of the wheels, allowing the subwoofer to be fixed in place once positioned to prevent unwanted movement during operation. The swivel capability of all four casters provides excellent maneuverability, enabling the user to pivot the subwoofer in tight spaces. By adding casters, this kit significantly reduces the physical strain and risk of injury associated with lifting and carrying heavy subwoofers, while also protecting floors from scratches and damage that can occur during dragging.

Constructed from robust materials such as zinc-plated steel or high-impact plastic with rubber wheels, the CK100 caster kit is built for durability and long-term use. The wheels are designed to be non-marking and may have a tread suitable for both indoor and light outdoor use. This accessory enhances the practicality and usability of Mackie's professional subwoofers, making them more adaptable to dynamic live sound environments and streamlining the setup and breakdown process for any event.
