The K&M 21367 distance rod is designed for live sound engineers and production teams who need a reliable mechanical link between a subwoofer pole socket and a satellite speaker cabinet. The patented Ring Lock expanding mandrel system grips the speaker's pole cup from the inside, eliminating the rattle and micro-movement that plagues standard friction-fit connections during high-SPL operation. This makes it a practical upgrade for touring rigs, rental inventory, and installed temporary systems where uptime and safety matter.
Height adjustment is handled by a spring-loaded bolt combined by a locking screw, allowing quick repositioning without tools while still locking solidly once set. The M20 threaded bolt at the base mates directly with standard subwoofer pole receivers, keeping integration straightforward across most portable PA platforms. The two-piece folding design simplifies transport and fits into standard speaker bags or cases alongside the cabinet. Steel construction supports a 35 kg load capacity, covering the weight range of most passive and powered satellite enclosures used in portable applications.
For rental houses and touring companies evaluating pole solutions, the Ring Lock system addresses the specific failure mode of satellite speakers shifting or vibrating off-axis mid-show. The moveable plastic splints distribute clamping force evenly around the tube interior, producing a fit that is both secure and acoustically quiet compared to single-point locking alternatives.
