Neumann KH 805

Uses:
• 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
