Robust drivers and cabinet



  • Low frequency extension for main loudspeakers down to 18 Hz
  • Low distortion magnetically shielded long-throw drivers
  • Reduced bass compression at high SPL from generously proportioned bass reflex ports
  • Large system with 6 dB higher output than KH 810
  • A main loudspeaker can be mounted onto an KH 870 to make a large 4-way column system
  • Allows main loudspeakers to play louder and with lower distortion
  • Wooden cabinet with a tough painted finish (anthracite or silver) and high density rubber isolating feet
  • Excellent self-damping properties leading to minimal cabinet resonances
  • Cabinet look conforms to the family design
