Designed to integrate seamlessly with leading L-Acoustics arrays, it provides impressive headroom and accurate transient response, maintaining clarity even at demanding show levels. Its front-loaded design and optimised venting help minimise turbulence and distortion, while the robust birch ply enclosure withstands the rigours of touring and intensive rental use. Typically partnered with L-Acoustics amplified controllers and presets, the SB28 supports standard and cardioid sub configurations for excellent low-end directivity and stage spill management. From arenas and festivals to high-spec fixed installs, this sub delivers consistent, musical bass that enhances impact without sacrificing definition. Whether extending the punch of rock and pop, underpinning electronic music, or adding weight to theatrical and corporate productions, the SB28 provides reliable performance day in, day out. A proven choice for professional hire inventories and venue upgrades seeking authoritative, scalable low-frequency reinforcement.\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\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE22.3.100.500\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"L-Acoustics","offers":[{"title":"Used Equipment","offer_id":63769709347193,"sku":null,"price":4023.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/EDM_20PHOTOS_20-_20BRAVEO_20-_202025-10-23T151044.365.png?v=1781545042","url":"https:\/\/stage-experts.com\/products\/stage22-l-acoustics-sb28-subwoofer","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
