KH 805 II
Subwoofer
From Neumann:
The KH 805 II is the perfect subwoofer for medium sized rooms, providing bass extension with Neumann precision. It includes a unique and flexible Bass Manager for stereo systems and can also be used in surround and immersive setups for LFE reproduction or with external bass management. Analog and digital inputs and outputs allow for flexible connectivity.
The KH 805 II improves on its predecessor in acoustic performance and adds new features. Thanks to a novel long-throw 10” woofer with Extremely Linear Force Factor (ELFF™) technology and intelligent protection limiters, the KH 805 II ensures exceptionally low distortion even at maximum SPLs.
The KH 805 II extends low frequency reproduction down to 16 Hz and delivers about twice the output of the KH 750 DSP. This makes the KH 805 II the perfect complement to mid-sized speakers such as the KH 150 and KH 310.
