Neumann - KH 750 DSP

The KH 750 DSP is a 10-inch subwoofer designed for smaller rooms and compact monitoring setups. It pairs well with the KH 80 DSP, KH 120, or KH 150. Unlike the larger KH 805 II, the 750 uses a sealed cabinet — no ports — which results in tighter transients and a smaller physical footprint. The trade-off is slightly less output (105dB max SPL vs 110dB for the 805 II), but in a home studio or edit suite, that's rarely a limitation.

A 256W Class D amp drives the long-throw woofer, which uses the same ELFF (Extremely Linear Force Factor) technology found in the 805 II to keep distortion low at high excursions. Internal DSP handles the 80Hz crossover (adjustable 60–100Hz via software) and enables room alignment via MA 1. Like the 805 II, the KH 750 DSP can also apply DSP correction to connected analog KH-line monitors — so pairing it with older Neumann speakers brings room calibration to the whole system. This isn't limited to Neumann's own lineup either: speakers from other manufacturers, such as Genelec or ADAM, can be connected and corrected as well — even if they aren't DSP-based themselves.

Connectivity covers balanced XLR in/out and digital BNC (AES3 / S/P-DIF, up to 192kHz). Four routing modes handle stereo bass management, external bass management, and LFE. An 8-position phase switch and continuous low cut help with room integration. Network control via RJ45 connects to MA 1 and the Neumann.Control app.

A good match for nearfield setups where space is tight but accurate low-end still matters.
