JBL Professional ACK1 Accessory Caster Kit for SRX900 Series Subwoofers

Make moving SRX900-series subwoofers fast, safe, and professional with the JBL Professional ACK1 accessory caster kit. Built for touring and installed AV environments, this caster kit transforms heavy cabinets into mobile assets so your crew can deploy, reconfigure, and store systems with less effort and downtime. The kit includes four tour-grade casters with 3-inch black polyurethane wheels and anti-rattle features for smooth, vibration-free rolling that protects delicate components. Each caster carries a load rating of about 220 lb, providing confidence when transporting large subwoofers between stages, studios, or security and surveillance control rooms. The discreet black housings keep the rear of cardioid stacks visually unobtrusive during monitoring or live events. Compatible with SRX918S and SRX928S cabinets and other JBL enclosures, the ACK1 installs quickly using the supplied hardware — ideal for rental houses, integrators, and AV technicians who need reliable mobility without modifying cabinets. Add the JBL Professional ACK1 caster kit to your toolkit to streamline transport and on-site setup. Contact your dealer or order now to improve workflow and protect your investment.
