Neumann - KH 805 II

The KH 805 II is a 10-inch bass reflex subwoofer built for medium-sized studios. It reaches down to a room-shattering 16Hz and delivers roughly twice the output of the smaller KH 750 DSP, making it a sensible partner for mid-sized monitors like the KH 150 or KH 310. A 222W Class D amp drives the long-throw woofer, which uses Neumann's ELFF (Extremely Linear Force Factor) design to keep distortion low even at high excursions.

Internal DSP handles an 80Hz crossover and enables room alignment via MA 1. Here's an added bonus: when paired with analog KH-line monitors (like the KH 310 or KH 420), the KH 805 II has enough processing power to align the entire stereo system (using MA 1) — not just the sub. So if you have an older analog Neumann setup, adding this sub also brings DSP room correction to your main speakers.

Connectivity includes balanced XLR in/out and a digital BNC input supporting AES3 and S/P-DIF up to 192kHz. Four routing modes cover stereo bass management, external bass management, and LFE duties. An 8-position phase switch and adjustable low cut help with placement and room integration. The cabinet is solid wood with front-firing ports and a protective metal grille.

A capable sub for studios that need extended low-end with the option of full system calibration.
