KV2 Audio has expanded its VHD Series with the VHD7000D Subwoofer Amplifier, engineered to drive all VHD, ES and SL subwoofer elements for large-scale events, nightclub installations and touring productions.
This universal bass amplifier is also fully compatible with third-party subwoofers – a first for KV2. An innovative power management system enables the VHD7000D to deliver 3.5kW long-term/7kW short-term output power into 2Ω, or 2.7kW long-term/3.6kW short-term into 4Ω from a 16A circuit, and offer a 10Hz to 500Hz frequency response.
An RMS limiter provides long-term protection for loudspeaker components by monitoring average power over time and analysing thermal behaviour to control temperature build-up. This ensures efficient power management, preventing overheating, compression and driver damage. Pre-configured within the VHD7000D’s factory presets, it maximises SPL output, minimises thermal compression at high temperatures, and maintains natural sound dynamics even during continuous high-output operation, ensuring consistent performance in demanding live and installation environments.
Another key feature is the adjustable notch filter for resonance suppression. It prevents excessive cone excursion that causes distortion, reduced clarity, and shortened lifespan. Essential for touring or permanent installations, it delivers clear, precise, and impactful audio with a balanced low-frequency response and improved definition across the bass range.
A peak limiter provides additional protection from mechanical damage to the drivers caused by signal peaks and ensuring the cones remain within their safe excursion range. The amplifier also incorporates a high-power switching mode power supply circuit, onboard overdrive protection and remote configuration capability via KV2’s Control and Diagnostics Tool.
