New Neumann stuff announcing Friday 9/12

We will see (soon)
 
I expect the 310 II will remain a small, horizontal, 3 way, 8 inch bass, dome midrange and closed option. If they changed something significant conceptionally, it would make little sense keeping the name 310.
The 350 has to be bigger anyway, so maybe they could make it ported. I would still be significantly smaller than the huge KH 420 (with 10 inch bass and big midrange-waveguide in a very deep box).

Second, I think the domed midrange is pretty good, but it can be refined further. ATC manages to keep the crossover point lower at 380 Hz, whereas Neumann crosses high at 570 Hz, surely with more than a decade of driver improvements, Neumann can offer a wider range, and that opens the woofer to higher excursion without IMD too.

From what I understand they intentionally cross fairly high - the atc is a bit of a unicorn of a mid dome that it can cross that low. It's a combination of the double suspension keeping rocking modes to a minimum at higher excursions and a pretty generous linear excursion. Neumann's mid isn't optimized for that and I'm not sure it could cross anywhere near there without a pretty deep waveguide. The few bare driver measures I've seen of it show ~500hz as the lowest useful XO point.

There's a fair bit of room to play with in the range.

KH 150: 20 L
KH 310a: 28 L
KH 420: 93 L

Neumann could easily make a KH 310 II around 35L and still have room for a KH 350 around 45/50 L.

Keep in mind the internal volumes are quite a bit off from that.

The 310 is about 16L, the 420 around 45. I'd bet the 150 is more like 10-12 internal.

Still, big jump from 16 to 45, they probably could build something around 25L internal with the same drivers in a vertical config.

Agreed, but it also shows that this extension is possible and that they could redesign their mid-range driver to make it happen. OFC, it's possible that it may be too expensive to integrate in a KH 310 II or that ATC has some patent that prevents other companies from developing a similar driver.

Yes, of course.
 
ported "medium sized" 3 way with 8" or 10" sounds perfect. Bought kh150s and 2 small subs this year so I may have some buyers regrets depending on what they release. The 150s are so close to being capable of biggish room capable without subs. Keep them under 6k per pair ideally but probably more like 7-8.
 
I'm waiting to see what the pricing of the new KH310 is. Took the plunge and bought a pair a couple of years ago, knowing there was a new version in development. Doubt I will be upgrading any time soon myself.
Don't need digital input or onboard DSP, and reckon the price will be high.
Also curious to see what discounts will be available on the current version to clear the old stock.
(This may be a cause of some annoyance, if they're massive!)

I doubt that there will be massive discounts: Thomann Germany offers only one left version of the KH 310 right now. The right version will be available "in several month". So I think they cleared their stock right in time ...
 
Aye, hopefully. Kinda gambled on the new version being out of my price range anyway. Figured digital input plus DSP alone, would hike up the potential price. Definitely looking forward to seeing what all the new Neumann options are though. Hopefully someone will be able to get some to Amir for testing.
(On a side note... Ain't it a bummer that good speakers are so damn heavy, and therefore prohibitively expensive to post. Never mind the whole tariff malarkey. WTF.)

well, the 350 would be a V-6, but a 310 would be a de-tuned version to hit a lower price point - vinyl seats instead of leather, and no dash clock. The 420 would obviously be a V-8.
Mischief managed!
 
Hmm, if the 805 II were turned sideways, it would actually fit under the desk! Fortunately I don't think I've ever pushed the 750 to its limits so unless the 805 is priced surprisingly low, the 750 will be safe.

Does anyone see how the Mk II versions measure better than MK I? I don't really see much besides 16 Hz.
But they look like a great option for upgrading analog Neumann multichannel-setups.
 
I'm questioning things. Numbers are from Neumann's website. Compare the version II and the base version.

KH870 II:

Bass capability: Maximum sound pressure in the half-space at 3% THD in 1 m (averaged between 50 Hz and 100 Hz)114.9 dB


KH870:

Bass capability: Maximum sound pressure in the half-space at 3% THD in 1 m (averaged between 50 Hz and 100 Hz)116.7 dB SPL


KH810 II:

Bass capability: Maximum sound pressure in the half-space at 3% THD in 1 m (averaged between 50 Hz and 100 Hz)109 dB


KH810:

Bass capability: Maximum sound pressure in the half-space at 3% THD in 1 m (averaged between 50 Hz and 100 Hz)110.7 dB SPL

That doesn't look very promising if that's the path they are taking.

Not promising ? What do you want more for subs this size, with only 20 or 25 cm (8 or 10 inches) drivers ?

But nothing about the future monitor range, maybe in the next days, or maybe soon, or much later. ??

Indeed: it would be disappointing not to see at least a KH 310 with DSP and the possibility for room EQ WITHOUT a subwoofer.
