In excellent cosmetic and technical condition, this two-cabinet package combines immense output with precise control. Across the pair you benefit from four large-format 21-inch woofers, with the active module delivering ultra-high current amplification to power the passive cabinet for a seamless, phase-coherent low-frequency foundation. Capable of up to 14,000W peak performance while running from a standard 16A supply, the VHD4.21 couples exceptional headroom with class-leading efficiency for reliable, real-world deployment. Expect deep extension, rapid transient response and authoritative punch that scale from dance events and arenas to demanding live sound and touring applications. Supplied as a complete two-piece system: 1x VHD4.21 Active and 1x VHD4.21 Passive. Ideal when you need stadium-grade low end without compromising control or power availability. Typical use: touring PA, large-scale events, festivals and high-SPL installations where consistent, impactful sub-bass is critical.\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\u003eKV2 Audio VHD4.21 Active subwoofer\u003c\/li\u003e\n  \u003cli\u003eKV2 Audio VHD4.21 Passive subwoofer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eSTAGE22.9.100.900\u003c\/strong\u003e\u003c\/small\u003e\u003c\/p\u003e","brand":"KV2 Audio","offers":[{"title":"New Equipment","offer_id":65053190848889,"sku":null,"price":11380.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0288\/2260\/1776\/files\/IMG_9324_20_289_29.webp?v=1793383692","url":"https:\/\/stage-experts.com\/products\/stage22-kv2-audio-vhd421-activepassive-set-technisch-frisch-von-kv2-in-cz-revidiert-und-geprft-optisch-und-technisch-in-top-zustand","provider":"Stage Experts Ltd","version":"1.0","type":"link"}
