Based on the excellent acoustical performance of the KH 810, the KH 805 is the optimal choice to be used in stereo applications, for example in combination with the KH 120 or 
KH 310.

The KH 805 has a unique 2.1/0.1 Bass manager which enables it to be used in many different applications. There are four routing modes to ensure maximum flexibility.  Fourth order crossovers and adaptable acoustical controls allow for seamless system integration, and the bass management function can be remotely controlled.

The KH 805 subwoofer is designed to complement our extensive range of monitors, and can be used in music, broadcast, and post production studios for tracking, mixing, and mastering.

•   Bass extension for loudspeakers down to 18 Hz
•   Increasing the maximum SPL of loudspeakers by up to 8 dB
•   Decreasing harmonic and intermodulation distortion of loudspeakers
•   Reproducing the LFE channel
•   Reproducing the “Sub” signal of a bass managed multichannel source
•   Making a Plane Wave Bass Array™ system
•   Working as an extension for KH 810, KH 870 and KH 805 subwoofer systems

Flexible electronics 

  2.0/ 0.1 Bass Management for stereo and externally bass managed applications
  Bypassable 4th order 80 Hz active crossover for maximum compatibility with consumer reproduction
  Four routing modes on right input connector:
  Right channel bass management
  LFE to subwoofer only up to 120 Hz
  Wide for multichannel systems where the bass management is in the source
  Daisy chain for subwoofer arrays
  Acoustical controls adapt the subwoofer’s response to the environment
  Output level
  Low cut
  Parametric equalizer
  45° step phase control
  Larger systems and Plane Wave Bass Arrays™ maybe constructed using the Daisy Chain output
  Remoteable electronics (REK 3) for installation convenience, less cabling, and convenience of use  
  Integrated electronic limiter for amplifier and driver protection
  Low heat dissipation amplifier

Robust driver and cabinet

  Low frequency extension for main loudspeakers down to 18 Hz
  Low distortion magnetically shielded long-throw driver
  Reduced bass compression at high SPL from generously proportioned bass reflex ports
  Allows main loudspeakers to play louder and with lower distortion
  Wooden cabinet with a tough painted finish (anthracite) and high density rubber isolating feet
  Excellent self-damping properties leading to minimal cabinet resonances
  Cabinet look conforms to the family design
