Neumann KH 805 II – Subwoofer with DSP

Deep Impact with Power and Precision

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.

The KH 805 II is DSP-controlled for superior sonic performance and seamless integration via MA 1 Automatic Monitor Alignment (sold separately). When combined with analog Neumann studio monitors such as the KH 120 A (discontinued), KH 310, or KH 420, it offers sufficient DSP-power for aligning the entire stereo system using MA 1, optimizing not only the frequency response but also the phase. The KH 805 II is therefore a massive upgrade for existing systems. Of course, the KH 805 II is also a perfect complement to Neumann’s DSP-equipped studio monitors.

Precision in Every Detail

As subwoofers are typically placed on the floor, a robust grille protects the driver from accidental damage. The rigid cabinet features a highly efficient bass reflex system, which is carefully engineered and tuned for the tightest bass reproduction – with inaudible port noise.

The two analog XLR inputs are electronically balanced, as are the two analog XLR outputs. The up to 192 kHz / 24-bit digital input (BNC) accepts both AES3 and S/P-DIF signals. The subwoofer has an Auto Standby function, which can be deactivated via a backplate switch.

The KH 805 II excels in music, broadcast, and post-production studios for tracking, mixing, and mastering.
