{"product_id":"stage22-barth-acoustic-systems-bsl-15","title":"Barth Acoustic Systems BSL-15 Subwoofer, 15in Neodymium Driver","description":"The Barth Acoustic Systems BSL-15 is a high-performance passive subwoofer designed for use with external amplifiers, crossovers and system controllers. Built around a 15-inch long-excursion neodymium driver, it delivers clean, powerful low end from 33 Hz, with excellent transient response up to around 130 Hz. An aerodynamically optimised port maximises acoustic efficiency while reducing turbulence and low-frequency distortion, ensuring tight, musical bass even at high output. Practical features include robust Speakon connections, an M20 threaded pole mount for straightforward satellite mounting, integrated carry handles and a durable black textured finish. A subsonic filter and low-pass crossover are recommended for optimum system performance. For system variants, the BSL-15.sp version adds combo XLR\/jack inputs and XLR outputs. Supplied complete with a protective hooded flight case, the BSL-15 is ready for demanding touring and installation duties. Perfect as a bass extension with high-output tops, it excels in concert halls, theatres, clubs, cinemas, auditoria, multi-purpose venues and houses of worship.\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\u003eHooded flight case\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE22.7.100.00\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"Barth Acoustic Systems","offers":[{"title":"Used Equipment","offer_id":64715709350265,"sku":null,"price":805.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/BSL-15-180x202.webp?v=1790530150","url":"https:\/\/stage-experts.com\/products\/stage22-barth-acoustic-systems-bsl-15","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
