{"product_id":"stage19-l-acoustics-sb28-used-subwoofer","title":"L-Acoustics SB28 Subwoofer – Dual 18-inch High-Power Bass","description":"The L-Acoustics SB28 is a dual 18-inch, high-power subwoofer designed for precise, extended low-frequency reinforcement in touring and installation environments. Its optimised bass-reflex enclosure with progressive-profile ports minimises turbulence at very high SPL, preserving punch, clarity and a consistent response into the lowest octave. High-efficiency drivers and robust thermal management reduce power compression, keeping headroom and tonal balance stable throughout long performances.\n\nPaired with LA8 amplified controllers, the SB28 benefits from dedicated factory presets for protection and voicing, including symmetrical and asymmetrical cardioid modes that deliver impressive rear rejection for cleaner stages and tighter audience coverage. The rugged cabinet supports flown clusters and ground-stacked arrays, integrates seamlessly with L-Acoustics full-range systems, and offers predictable, repeatable results across a wide range of venues.\n\nFrom arenas and outdoor festivals to theatres and premium clubs, the SB28 delivers authoritative bandwidth, control and impact that underpin modern sound reinforcement. Choose it when you need powerful, accurate sub-bass with flexible deployment and consistent results show after show.\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\u003eL-Acoustics SB28 Subwoofer, Dual 18-inch High-Power Bass\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE19.2.100.550\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"L-Acoustics","offers":[{"title":"Used Equipment","offer_id":57368704123257,"sku":null,"price":2931.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/SB284.jpg?v=1780427076","url":"https:\/\/stage-experts.com\/products\/stage19-l-acoustics-sb28-used-subwoofer","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
