The On-Stage SS7745LOK Adjustable Subwoofer Attachment Shaft is a heavy-duty, utility-grade steel pole engineered to securely mount satellite PA speakers directly atop subwoofer cabinets. Designed to bypass the need for space-consuming floor tripod stands, this professional-grade audio accessory streamlines live sound setups for mobile DJs, touring bands, and corporate AV tech crews. The core engineering centerpiece is the patent-pending CABLOK anti-wobble mechanism built into the mounting end. Managed by a comfortable, oversized manual activation ring, this system deploys integrated internal pressure pads that expand outward into the speaker socket, effectively filling all manufacturing tolerances and structural gaps to eliminate crooked speaker tilt and physical wobble caused by powerful sub bass frequencies or high winds.

Constructed completely from robust, thick-walled steel tubing, the assembly is finished in a durable, scratch-resistant black powder coating that maintains a clean, unobtrusive look on dark commercial stages. For exceptional operational versatility, the shaft features a fully reversible pole design, giving audio engineers the flexibility to position the expanding locking adapter inside either the upper satellite speaker cabinet or the lower subwoofer top-hat base. Supporting an industry-standard 1 3/8-inch diameter, it accommodates a broad assortment of commercial pro-audio speaker models while maintaining a maximum weight handling threshold of 100 pounds. Height settings can be customized seamlessly from 32.5 to 47 inches, allowing users to precisely align sound projection paths over the ears of an audience.
