Neumann KH150 Review

Thanks for the measurements.
They just released a new firmware update, "1_1_14-2760."
Does anyone have any information about what's been improved/corrected/fixed?

By the way, I have good information that the KH310-II is close to release, and I've also heard something about a KH350...

We'll keep an eye out.

Looking forward to it. About a year later than originally hinted. Better late than never.

I'll believe it when I see it.
 
How about throughout the volume range?
That's what this review is here for, You've got all the significant measurements to answer that question. There's just a handfull of speakers on the market that reach that level of performance anyway, and at that price, none I reckon.

I hear you but I’m not aware of the audibility levels of IMD and at which frequencies we are most sensitive.
 
Holy crap that's incredible inductance control. This is very close to Purifi level performance. My hat's off to Neumann. Is the woofer using a neo motor?
Doesn't appear to be, no. Looks like a typical ceramic mag (which is fine, neo's big advantage is its strength per weight. Ceramic is just fine for something that doesn't need to be moved regularly or doesn't have space restrictions.

Without a teardown of the woofer - which frankly, I doubt we'll ever see - we won't know what makes the electrical characteristics as good as they are.
 
I'm looking for advice on the Neumann KH150 vs. Ascilab A6B or KEF R3. I listen at 2–2.5 meters and need clear separation/clarity for dense orchestral/prog music. I previously found the Genelec 8331A too muddy at this distance and I'm worried the KH150 might have similar issues from the multitone distortion measurements. Since I can't audition them locally, I'd love to hear some experiences/advice.

If purchasing the kh150s, I would be adding an kh 805 down the line - the ease of subwoofer integration is a very appealing part of the Neumann ecosystem.
 
I have the KH120s (no sub) and the Genelec 8351bs (with the Genelec 7360 sub). The Genelec DSP system is fantastic and flexible, I can't imagine how it would sound muddy unless it's your room or setup.

I love both brands.

I also listen do orchestral and prog for what it's worth.
 
I would also include the Ascilab A6B / C6B in my very shortlist.

The energy distribution into the room (Directivity plot) is even more even with this speaker than with the Nemann KH 150. This could potentially lead to a slightly more convincing "imaging" or clearer projection of the musicians into your living room when listening to, for example, chamber music, giving you an even stronger feeling that the musicians are really present (Picture 1 and 2).

Thanks to the Purify drivers, the harmonic distortion also appears to be more or less at world-record levels above 200 Hz (Picture 3 shows the C6B which costs 1/3 of the A6B).

Another argument for HiRes believers (to whom I definitely belong, although this is always somewhat dismissed as incompetence here ;)) could be the fact that the Ascilab A6B / C6B, unlike the Neumann KH 150, is not limited to a 24 kHz bandwidth (losses when switching the sampling frequency from multiples of 22.05 kHz to multiples of 24 kHz - internal signal processing in the KH 150 - should also be considered in my opinion!).

Needless to say that, as any speaker in the world, also the AsciLab A6B will benefit from two good subwoofers and room correction in the lower frequencies!!!

Perfection!

1) Have You calibrated Your system by Genelec GLM?
2) Which Genelec subwoofer You have?
3) Genelec 8331A is not optimal for midfield listetning (Genelec 8341A x2 + Genelec 7370A is optimal).
 
Nice! When I ask things already explained I excuse myself, but what microphone do you use? Or is there a link to your measurement method?
