A DSP-powered sub for professional monitoring

The Neumann KH 750 DSP is a compact, high-performance subwoofer designed for professional studio monitoring in small to mid-sized control rooms. Featuring a 10" long-throw driver in a sealed cabinet, it delivers tight, controlled bass with minimal group delay. The integrated DSP engine enhances bass management and room correction, making it an ideal companion for Neumann KH-series monitors, including the KH 80 DSP, KH 120, and KH 310. While analogue Neumann monitors also benefit from enhanced phase response when connected to the KH 750 DSP, the system truly shines when paired with the optional MA 1 Automatic Monitor Alignment system. The Neumann.Control iPad app further extends functionality, allowing precise control over bass settings, crossover configurations, and calibration options. The KH 750 DSP features both analogue (XLR) and digital inputs (AES3 and S/PDIF via BNC), offering high-quality internal conversion and four routing modes for maximum versatility.

iPad-based control and calibration

The Neumann.Control iPad app transforms the KH 750 DSP into the central control hub of a Neumann stereo monitoring setup. When connected via Ethernet, it enables detailed system calibration, adjusting speaker response based on room size, speaker position, and other key factors - without requiring an external measurement microphone such as the MA 1. This allows for automatic system calibration, ensuring an optimum frequency response. Users can also manually adjust bass levels or apply external processing. Additionally, the Neumann.Control app provides monitoring control functions such as volume adjustments, solo/mute functions, and preset management, offering a streamlined and intuitive user experience.

Versatile bass extension

The KH 750 DSP is ideal for extending the low-frequency response of a monitoring system or offloading bass reproduction from main speakers - whether in a professional studio or home production environment. While it performs best in small to mid-sized spaces, its 10" long-throw driver, EELF™ (Extremely Linear Force Factor) technology, and 256W amplifier ensure highly accurate low-end performance for music production, post-production, and broadcast applications. The KH 750 DSP also integrates seamlessly into multichannel systems with independent bass management, allowing flexible configurations including LFE channels or pairing with larger Neumann subwoofers such as the KH 810 or KH 870. Its advanced DSP processing makes it particularly well-suited for use with other Neumann monitors, ensuring a coherent and phase-accurate sound across all speakers.

Bringing DSP technology to analogue Neumann systems

Analogue Neumann monitors connected to the KH 750 DSP also benefit from its DSP processing, even if they do not have built-in DSP themselves. In addition to convenient remote control via the app, the KH 750 DSP improves phase response, which can often be inconsistent in analogue multi-speaker setups. The built-in FIR filters include dedicated presets for Neumann KH 120, KH 310, and KH 420 monitors, ensuring precise calibration across the entire system. However, since the KH 80 DSP already includes its own onboard DSP, it does not require additional correction when paired with the KH 750 DSP.

About Neumann

Georg Neumann GmbH was founded in Berlin in 1928 - and is certainly one of the most famous brands of microphones in the world. However, this is not the company's only sphere of activity. For many years, the versatile inventor and pioneer Georg Neumann was also involved with vinyl record cutting machines and the development of rechargeable batteries. The technology he developed is still the basis for this now crucial and rapidly expanding market. What is more, for many years the company built highly personalised sound control systems for broadcast studios/theatres and concert halls, and for several years also studio monitors. In 1991, Neumann became part of the Sennheiser group of companies, and in 1999 was the first German company to receive the Technical Grammy for their overall technical achievements.

Seamless Neumann MA 1 system integration

The KH 750 DSP also enables automatic calibration for Neumann analogue monitors (such as the KH 120 or KH 310) using the Neumann MA 1 system. This system consists of a pre-calibrated measurement microphone and advanced software, developed in collaboration with the Fraunhofer Institute, featuring cutting-edge amplitude and phase correction algorithms. The MA 1 makes it easy to optimise speaker performance for any listening environment - without requiring advanced knowledge of room acoustics. The Neumann MA 1 system is also available as part of the Neumann Monitor Alignment Kit 1 (article no. 512646), which includes the KH 750 DSP and MA 1 for a complete calibration solution.

Mindblowing, OMG

2002fede 03.03.2021

I don't know where to start seriously, I am beyond happy. I have recently bought the KH80 from Neumann and I started to realize how precised everything was coming out, from reverb tails to transient responses, etc...so I've bought the MA 1 mic and decided to give it a try with the DSP mode. Needless to say I was already speechless, the linearity was yes...linear, but without any side effects from other softwares like Sonarworks for instance. I then decided to go full beast and buy their DSP sub and....OMG!...I have just finished calibrating the kh 80 with the kh 750 and I am MINDBLOWED. Believe me, I went to so many studios and I know how a reference system should sound and this one guys and girls...it's the ultimate weapon. So precise, so tight, super deep and whatever you wanna add. I'd say they are easily compared to some 10k speakers in a seriously well treated room. Go for it!...PS: I never review shit, but I HAD to let you guys know about this one

Nice complement to KH 120 speakers

TonalHarmony 29.09.2020

Very good build and perfect complement to my KH 120 nearfield speakers.
However, the software for setting up is locked and vendor specific (Apple iPad) and requires a fairly new OS version.
I have an iPad which is a few years old and which I do not use anymore, but I can not use it because of an older OS version.
It can not be upgraded to the required version, and find it way too expensive to buy a new iPad just and only for this purpose.
It would be better to adapt the software suitable for older iPad's as well or release a version for eg Windows or Android as well.
Therefore only 4 stars, but 4,5 stars would be more appropriate.

Great Sound

PhilsHarmony 28.03.2023

Got the KH 750 DSP as a low end addition to my KH 120As. Calibration didn't work at first, but after contacting Neumann, they told me to wait for the next update. Did that and calibration worked fine that time (didn't recognize my 120s in the calibration software settings before, now it does).

My room is quite close to 25m², so I was looking for a subwoofer that was suited for smaller rooms. So far my neighbors haven't complained. It's expensive, but good quality.

I use the subwoofer in my home studio in combination with the Neumann KH120a.

Thanks to the built-in DSP and iPad application (it is a pity that only for this platform) it is possible to set the whole system and configure it to your needs very quickly. A nice surprise is the possibility of delaying part of the system to ensure the best results. This is the first sub that I was able to set up without any problem.

Thanks to the proper placement and the fact that the enclosure is closed, I have no problem with resonances in the room (I have several bass traps installed) and I can hear even the lowest frequencies - that's crucial because I work mostly on electronic and rap music.

Saving poorly produced numbers I don't have to wonder if any elements get in my way but I just hear it. And customers hear it too. :)
