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 KH 80 DSP, KH 120 or KH 310.

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

APPLICATIONS

• 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 line subwoofer systems

(1)
Computer mechanically modeled cabinet design using Low resonance Integral Molding™ (LRIM™) materials

• Wooden cabinet with a tough painted finish and high density rubber isolating feet
• Excellent self-damping properties leading to minimal cabinet resonances
• No standing wave resonances inside cabinet
• Reduced cabinet resonances

(2)
In-house modelled long-throw composite sandwich cone bass driver with Extremely Linear Force Factor™ (ELFF™), magnetic shielding, flow optimized die cast basket and robust built-in grille

• Damping of break up modes brings low distortion at high sound levels
• Linear pistonic motor gives a very low harmonic distortion even at high excursions
• Reduced air noise and improved rocking modes
• Grille protects against mechanical damage

(3)
Large high-capacity flow-optimized bass reflex ports

• Fast bass transient response
• Reduced bass compression at high output levels
• Can be flush mounted

(4)
2.0/ 0.1 Bass Management

• Stereo and externally bass managed applications
• Bypassable 4th order 80 Hz active crossover for maximum compatibility with consumer reproduction systems
• Allows main loudspeakers to play louder and with lower distortion

(5)
Four routing modes

• 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

(6)
XLR electronically balanced analogue inputs and outputs

• Standard interfacing to professional equipment
• Daisy chain output for subwoofer arrays

(7)
Wide range input gain and output level controls

• Easier interfacing with signal sources

8-position phase control, continuous low cut control and parametric equalizer

• More control in diverse acoustical environments
• Parametric equalizer is bypassable if not needed

(8)
Universal switched-mode power supply (100 … 240 V)

• One version works in any country and robust to poor quality mains supply

(9)
Ground lift

• Reduced noise in electrically noisy environments and over-comes ground loops

(10)
Low heat dissipation amplifiers with large headroom and overheat limiting

• Improved transient response
• Assured reliability and safety

Separate fast acting thermo limiter to protect the voice coil and power amplifier

• Soft clip and excursion limiters
• Increases system reliability
• Allows extraction of the maximum performance from the system

(11)
Installation flexibility

• Remoteable electronics (REK 3) for ease of installation, less cabling, and convenience of use
