It is engineered for use with d\u0026amp;b system amplifiers, ensuring consistent performance, precise protection, and straightforward deployment through factory presets. Rugged construction and proven touring reliability make the B4 suitable for both mobile and installed sound environments. From live music and theatre to corporate events and houses of worship, it enhances intelligibility and impact without the complexity of large sub arrays. Choose the B4 when you need controlled, directional low end in tight spaces or challenging acoustics. Ideal for professionals seeking clean, impactful bass with minimal stage spill and a tidy, predictable setup.\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 Audio Technik B4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE22.2.100.200\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"d\u0026b audiotechnik","offers":[{"title":"Used Equipment","offer_id":64494121255289,"sku":null,"price":2529.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/IMG_0025_20_2829_29.webp?v=1788718467","url":"https:\/\/stage-experts.com\/products\/stage22-db-audio-technik-b4","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
