Collector items, original Klein & Hummel O300 active nearfield monitors (pair, left/right), The OG from the classic K&H era (pre-Neumann rebrand). Price is EUR 2,500 (EUR 1,250 per speaker).

These helped define the sound of countless project studios, mastering suites, and broadcast rooms in the 2000s/early 2010s. Many engineers still prefer the original O300 voicing over the later Neumann KH310 for its slightly warmer, more musical character, analog-like depth, and engaging low-end punch without boom.

  • Excellent overall condition – smoke-free studio use only, no major scratches, dents, or wear on cabinets/faceplates. See pictures from all sides.
  • Fully functional (no buzz, no coil whine, both channels perfectly balanced).
  • Original condition no mods or repairs.
  • From a careful owner, looking for another careful owner

These are true collector pieces – part of pro audio history. The KH O300 holds a special place for those who want that vintage K&H musicality in reference monitoring. It will not disappoint you.
