The KV2 Audio VHD4.21 is a reference-grade subwoofer system supplied here as an active + passive set, recently overhauled and factory-tested by KV2 in the Czech Republic. 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.
