Its innovative driver configuration provides inherent rear rejection, improving clarity across the audience area and reducing onstage rumble. The result is punchy, musical bass with excellent pattern control, ideal where precise low-end management is essential. Designed for professional sound reinforcement, the B4-SUB integrates seamlessly into d\u0026amp;b systems and is well suited to both mobile and installed applications. Rugged construction, tour-ready fittings and consistent voicing make it a reliable choice for production companies and venues alike. Whether used as a standalone LF extension or combined in arrays, it offers impressive output while maintaining a small footprint for efficient deployment in tight spaces. Typical use includes live music, theatre, corporate events and clubs where articulate, directional bass is required to enhance intelligibility and audience experience.\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\u003ed\u0026amp;b audiotechnik B4-SUB Cardioid Subwoofer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE22.2.100.490\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"d\u0026b audiotechnik","offers":[{"title":"Used Equipment","offer_id":63768758550905,"sku":null,"price":2863.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/IMG_3086_20_2812_29.jpg?v=1781537991","url":"https:\/\/stage-experts.com\/products\/stage22-db-audiotechnik-b4-sub-kardioider-subwoofer","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
