About the KV2 Audio ESR3000MkII
The KV2 Audio ESR3000MkII is a rack-mounted, three-way active control and amplification system purpose-built for the KV2 Audio ESR full-range loudspeaker series, including the ESR215MkII. Each unit incorporates six amplifiers: two 100-watt Class AB push-pull low-intermodulation amplifiers for high frequencies, two 200-watt Class AB push-pull low-intermodulation amplifiers for mid frequencies, and two 1000-watt high-efficiency current-enhancing switch-mode amplifiers for bass. The ESR3000MkII also handles signal processing, crossover functions and control for an external subwoofer cabinet via an external amplifier. In stereo configuration it powers two ESR cabinets, making it suited to fixed installations in theatres, cultural centres and music venues from single column enclosures through to medium and larger venues.
KV2 Audio ESR3000MkII — buyer FAQs
What is the KV2 Audio ESR3000MkII and what is it designed to do?
The KV2 Audio ESR3000MkII is a rack-mounted, three-way active control and amplification system built specifically for the KV2 Audio ESR full-range loudspeaker series.

This tri-amplified arrangement is dedicated to a single stereo pair of ESR cabinets.
Which loudspeaker cabinets is the second-hand ESR3000MkII typically paired with?
The ESR3000MkII is designed to work with the KV2 Audio ESR full-range loudspeaker series, with the ESR215MkII being a confirmed compatible cabinet. In stereo configuration one ESR3000MkII unit powers two ESR cabinets. It is suited to installations ranging from single column enclosures at stage sides and prosceniums through to medium and larger venues.
Who makes the ESR3000MkII and where does it fit in their product range?
The ESR3000MkII is made by KV2 Audio, a Czech professional audio manufacturer known for active and passive loudspeaker systems, subwoofers and amplifiers with an emphasis on analogue signal processing. The ESR3000MkII sits within KV2's installation-focused ESR range, acting as the dedicated amplification and processing brain for ESR full-range cabinets in theatres, cultural centres and music venues.
What should I check when buying a used KV2 Audio ESR3000MkII?
Confirm which ESR cabinet configuration the unit was running, as the ESR3000MkII is purpose-built for the KV2 ESR series and stereo-pairs two cabinets per unit. Check that all six amplifier channels are functional across the three frequency bands, that signal processing and crossover sections operate correctly, and that the subwoofer output path works if that feature is needed. Used listings on this page carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide/ covers the full process.
