Live sound setups demand hardware that manages weight and adjustment without slowing the pace of a gig. The Ultimate Support SP-90B TeleLock sub-woofer speaker pole delivers on this expectation, combining sturdy, lightweight aluminum with field-serviceable construction for reliability on the road and in the venue. Its TeleLock collar stands out during real-world use, allowing hands to safely raise or lower a speaker—even with full weight on the pole—thanks to a positive-locking mechanism that snaps into position as the height is set. The dual-mode subwoofer adapter and adjustable speaker adapter fit standard enclosures and modern threaded mounts, streamlining swaps between main and sub configurations. When working with heavier cabinets, the thick-walled tubing and 75 lb. rating keep movement steady, resisting flex or wobble during high-output sets. At just 3.6 lb., the pole makes load-ins manageable for solo acts or teams, and the height range brings flexibility for tight corners and elevated arrays. For users who need a dependable, quick-adjust speaker solution in changing stage conditions, the SP-90B sub-woofer pole blends stable handling with a practical footprint that rewards repeated use.
