{"product_id":"stage21-soundsale-a-stack-2-flightcase","title":"Soundsale A-STACK (2) with Flightcase – Ground-Stack Frame","description":"The Soundsale A-STACK is a fixed array frame designed to interface L-Acoustics KS21 subwoofers with A10 or A15 enclosures in a secure ground-stacked configuration. This bundle includes two A-STACK frames supplied in a protective flightcase. For safe deployment, A-STACK should be used with two KS21-OUTRIG under each KS21 to ensure stability. Locating pins align with the cabinet lodgings, allowing the HF section to be positioned on either side for optimal coverage. Each frame is secured to the enclosure and subwoofer via threaded knobs; the subwoofer knob is compatible only with KS21 models fitted with the pole-mount insert. The frame’s opening angle is adjustable from 20° to 35°; note that the frame label indicates the accessory’s opening angle, not the enclosure site angle. Built for touring and rental, A-STACK delivers fast, reliable setup and precise aiming for compact A-Series ground stacks. Ideal for live sound, corporate events and installs needing flexible, repeatable KS21 + A10\/A15 stacking with professional handling and transit protection.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIncludes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e2 x A-STACK frames\u003c\/li\u003e\n  \u003cli\u003e1 x flightcase\u003c\/li\u003e\n  \u003cli\u003eFlight case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE21.1.100.599\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"Soundsale","offers":[{"title":"Used Equipment","offer_id":57405420634489,"sku":null,"price":1838.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/soundsale-astack-frame-lacoustics-6.jpg?v=1780998943","url":"https:\/\/stage-experts.com\/products\/stage21-soundsale-a-stack-2-flightcase","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
