KH 805 – Active Studio Subwoofer

KH 805 – Active Studio Subwoofer

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
