- Two-Piece Telescopic Design Provides Flexible Speaker Positioning

- Steel Construction Built To Handle Repeated Touring And Install Use
- Compatible With K&M 20811 And 21411 Speaker Stands
The K&M 21231 telescopic boom arm is designed for audio engineers, production crews, and installed sound technicians who need flexible speaker placement beyond what a fixed stand allows. Built from steel with a two-piece telescopic design, it provides a wide range of positioning options for delay speakers, fill cabinets, or monitoring setups in live sound and installed environments.
Engineered specifically for use with K&M model 20811 and 21411 speaker stands, this boom arm integrates cleanly into existing K&M stand systems without adapters or workarounds. The 1/2" connecting thread locks into the stand column, while the 3/8" threaded end accepts a standard speaker bracket. A T-bar locking screw clamps the telescopic sections firmly at any chosen extension, and the included adjustable heavy counterweight keeps the arm balanced under load.
For touring rigs and portable installs where positioning flexibility directly affects coverage and intelligibility, this boom arm solves the problem that fixed-column stands cannot. The steel construction handles the physical demands of repeated rigging, and the adjustable counterweight removes the guesswork from balancing heavier speaker enclosures at extended reach.
