K&M 21337 Adjustable M20 Distance Rod for Speaker & Subwoofer - Black
The K&M 21337 is an Adjustable M20 Distance Rod connecting a satellite speaker to a subwoofer with height adjustment from 905mm to 1,450mm, a spring-loaded locking screw with safety bolt and a 35kg maximum load capacity — providing a secure, precise and vertically stable speaker stacking solution.
The K&M 21337 is a robust steel distance rod designed to connect a satellite loudspeaker to a subwoofer, allowing the complete speaker stack to be height-adjusted for optimal positioning in any live sound or installation environment. The M20 threaded base provides a secure attachment to compatible subwoofers — including those with an M20 threaded pole mount socket — whilst the 35mm tube end accommodates the pole mount sockets of a wide range of satellite loudspeakers for versatile system compatibility. A mounting aid is included to simplify the process of securing the satellite speaker to the rod.
Height adjusts between 905mm and 1,450mm via a spring-loaded locking screw with a safety bolt that protects against unwanted movement and provides zero backlash — ensuring the satellite speaker remains in an absolute vertical position throughout use without any risk of slipping or shifting during a performance. The 2-piece steel construction delivers a maximum load capacity of 35kg, making the 21337 suitable for a wide range of passive and active satellite loudspeakers. This rod is compatible with the K&M 24116 connector plate for expanded mounting options.
