I usually mix at around 75dB and i never felt the kh310s struggled with bass but with bass heavy music i can hear the difference straight away but only because i had the kh750 to compare it with. The analogy would be driving a car with 2 people vs 4.

With the K+H o300 i had before they definitely needed subs to help them. The kh310s not so much but the whole system sounds better and has more power.

Still not to keen to integrate a sub again, as the room is practically the living room even though it is treated with a Bass trap and some broadband absorbers. But the opening up on the 310's when used with a sub sounds interesting. Do you think this is especially when mixing rather loud? Like 80dB and up?

Any word on the street from Neumann about a macOS desktop version of the Neumann.Control app? Or even an iOS phone ready version? Thinking about adding the KH 750 to my KH80s but don't currently own an iPad or want to buy one just to take advantage of setting this thing up.

Same here. I was thinking hard about these but am now thinking twice - no offense to any brand but I just don’t trust any (non-software) brand to maintain their proprietary software for the long term.

I wish it had simple controls on the speaker like the 310

I own a pair of KH120's. I am awaiting a KH750 sub to arrive in the next few days. I'm a bit confused as to whether there is an additional level of DSP adjustability using the KH750 with the KH80DSP as opposed to my current KH120's? Is there any advantage of using the 80DSP over the 120 because of the "DSP" designation in the 80 and the 80 beingdesigned with the feature set in mind?

Also, once you use the iPad to set things up will I need it after being dialed in? In other words can I borrow my grandmas iPad to set it all up and then return it back to her, or do I need to have the iPad booted and on my desktop to utilize the features in realtime.

Do you think guys the combination of Neumann KH80 + kh750 would be good for a small room (4x3 meters) with Acoustic Treatment from Hofa. My budget is 2200 euros.

I have worked with Adam S2A and S2V a long period of time and I love them, but they are out of my budget.

I have read good reviews about Neumann, flat response down to 20hz.

I would like to hear what you think, your recommendations and experience. Really appreciate it. thanks!

If you set the dspEQ properly the bass is so clean down to 20Hz. Also got the Kh120, Kh80 here for some testing. These two works fine with KH750 but you really miss the warm gentle mid Range from the KH310.

Kh80/kh120 with Kh750 lack a bit of mid warmth imho. Kh80 are a tad more coherent and faster transient then kh310.

But..Kh310/kh750 just sounds so natural and right in every aspect to me. Besides audible check I was often take a look at my Rme Adi 2Dac graphic analyzer, everything audible comes from kh310/kh750 coinciding exactly with the RME Analyzer.

Had also the Genelec 8831 here for some test with kh750 but find them too bright and lack in mid warmth. Same behavior like Kh80/kh120, should be the cabinet size in general.

Kh750 dsp App is a lifesaver in bad environment like mine. Its a similar solution to GLM if you can use REW with a calibrated mic. We rebuild our house and I have to work in a temporary space.

I fixed the FR with kh750, works great despites the time domain issues in this room. Attached is before/after FR, great compromise for the next month in this space.
This looks quite interesting for me as I have a very odd 36 HZ peak with a reverb time close to a second. If the KH 750 can fix this, I'm going to take one.

80 Hz crossover is the standard for THX systems, and most people using systems for music set the subs differently. 50 Hz or so is still directional and is beneficial to hear from the stereo mains.

In general you want to set the subwoofer crossover to 1.5 octave above the -3db low point of the mains.

One subwoofer is generally not optimum, and can actually cause more problems in a room. Two subwoofers are usually better as they excite the bass peaks and dips less than one sub.
What is the rational of the last statement of using two subs rather then just one? Depends that also of phase and positioning of the sub or basically just because of the SPL potential?

I've been able to test 2x KH750 w/ KH310s due to receiving a damaged one (**** fedex for ruining a perfectly good sub) and here's what I've gotta say.

If you listen to a bunch of leftfield bass like I do it's a lot more enjoyable. Having two subs really gives you that body-shaking feel compared to one. Adding 1 sub gives you much more headroom on your mains and you should pretty much never see the limiters kick on. It adds a transparent support to the KH310s, like other users have said - you can barely tell you added a sub until you listen closely and realize you added another octave to your range. Adding another sub however makes it much more obvious, especially at lower volumes.

If adding a kh750 to the setup gives you 10-15% more sound, I would say adding 1 more sub gives you 5% more. Diminishing returns for sure, but when I have money burning a hole in my pocket I'm definitely going to buy another one in the future IF:

Now here I will list some huge glaring problems.

1. The DSP app is a huge problem. Using it on my iPad pro every time I start it up it has to connect to the network and look for devices which takes about 5-10 seconds. That might not seem like a huge deal but just think about doing this in terms of workflow.

2. No dual sub configurations in the DSP app. This means you have to switch between setups in the DSP app which is painful because the problem in #1 happens TWICE.

3. Spdif. Not really a problem - just the nature of digital out but it will make the other problems much more obvious.

You should be using SPDIF out to avoid an extra A/D conversion for nothing.

This means stuff like dimming and muting mains or subs has to be done on the DSP app. So you're stuck with problems #1 and #2 because you *have* to use the DSP app. Yikes.

I'm not going to get into whether 2 subs is better than 1. That's going to be largely dependent on your room. I use sonarworks in a treated room so having 1 sub is great, having 2 subs is great. It's just all great.


I really hope the only 1 Sub config is an iOS limitation and not a hardware limitation. If so they should really make an macOS app for it - who likes opening up their ipad to control stuff when they are deep in a project anyway? I'm not really sure how to contact Neumann to give them this feedback. Their site is hard to navigate and only list service contact and I'm sure seinheisser USA doesn't give a **** about my feedback on neumann speakers.

The Focal Sub6 still does.

I'm working in a small room at the moment and trying to decide if either the Focal or the Neumann would work for me. I have Sonarworks so maybe I'd be fine with either one but the added control, potential control from what I've read here, of the Neumann would be a benefit.

My experience with kh750 was not good on a small room (14 square meters).
Without control app was sh.t. With adjustments it improved the responses significantly but creating a weird low freq effect it was like an artificial sound and moving slightly to other points on the room the sound changed completely. the Mids were affected as well.

My conclusion was my small room can only manage properly the typical range of frequencies of a 6.5 or smaller woofer. Just looking for something neutral, detailed but at the same time easy to manage I decided to improve the acoustics of my room and went for the PMC result 6. I use my headphones for very low frequencies. Extremely happy so far.

Maybe your room is completely different... the Neumann combo kh80+750 sounds amazing but requires medium/large space or invest a lot on the acoustics.

I'm coming to the same conclusion. I'm not reading success stories with the KH750 as I research it, more just like yours.

Switching to the PMC Result 6 or the Barefoot Footprint 02 is looking like a better option for me.

No matter what monitors you install into a room, the proper acoustical treatment of that room is critical to getting the best and designed performance of the monitors.

Absolutely true and understood by most I'm sure.

You’d think. But not always so. And I’m not selling anything. Not sure what the snarky plug thing is all about. Just giving perspective based on a long-time KH user. Just trying to help a GSr out.

Huh, that link in your previous post, the one to your business in room treatment, is gone from this one.

That's curious !

Nothing curious about it. Gear Slutz only puts users' signature line on certain posts (for example look on this page up at posts number 97 and 98. Same user, sig line on first post, not on 2nd one). I don't sell product, room treatment or the like. I have a business, recording studio, since 2004. It's a personal studio, but I do some work for certain persons that I choose to work with. So my website indicates that as well. If you'd like to see the link again to police my selling of product, feel free. The website is www.solutionroom.com

There is no room treatment that I sell, as you say. I provide a service, mostly to close acquaintances and the like. I designed and built this studio. So I know every detail that went into it. I don't design and build studios for customers. I did it for myself. I believe I've explained that well enough.

Listen, I'm not trying to get into a pissing contest here. Like I said, I was and am just trying to give my personal perspective on the Neumann monitor line, as a satisfied user in the real world.

Thread hi-jack over. I hope.
