{"product_id":"k-m-21231-500-55","title":"K\u0026M 21231 Telescopic Boom Arm For Speaker Stands | Black","description":"\u003cp\u003eThe K\u0026amp;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.\u003c\/p\u003e\u003cp\u003eEngineered specifically for use with K\u0026amp;M model 20811 and 21411 speaker stands, this boom arm integrates cleanly into existing K\u0026amp;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.\u003c\/p\u003e\u003cp\u003eFor 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.\u003c\/p\u003e","brand":"Connolly","offers":[{"title":"Default Title","offer_id":51442926813368,"sku":"43071","price":207.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/43071_K_M-21231-Telescopic-Boom-Arm-For-Speaker-Stands-_-Black_ALT01sqr.jpg?v=1790884394","url":"https:\/\/soundpro.com\/products\/k-m-21231-500-55","provider":"SoundPro","version":"1.0","type":"link"}
