No, it's not true. I believe the technical term is that they are 'talking utter bollarks'!
If you check the manuals, Neumann specify the minimum listening distance as 0.75m, and the recommended distance 1 to 2.5 metres. For comparison, the equivalent figures for the KH120 are: minimum: 0.75m, and recommended, 1 to 2 metres.
So the KH310 can be used at exactly the same minimum and recommended distances as a KH120 and in the same sized room, if desired... but it can also be used at a greater distance and in a larger room if necessary/appropriate.
This is all entirely obvious, though... if you think about it the tweeter and midrange unit in the KH310 are in a very similar physical arrangement/spacing to a KH120 or KH80... So the minimum and recommended listening distances are bound to be quite similar.
I think ideally I would love a DSP version of the KH120’s but have no idea if Neumann have any plans for this?
I'd be amazed if they didn't, especially given the impressive capabilities of the KH80 ... but I'm afraid I can't offer any wisdom as to when new digital models might be launched... I'd have thought fairly soon... and NAMM is coming up...
I’ve also considered adding a second sub as I’ve read this helps with node averaging but again don’t know if this is true?
Yes, it is sometimes done and it can work if engineered carefully... but to be effective you'd need very accurate control over the time (phase) alignment of the two subs in relation to the main monitors (and each other).
To be blunt, though, I'd still much rather invest in sorting the basic room's LF response out than fill it with yet another trouser-flapper. When you're in a hole, stop digging, as the saying goes!
Not sure if I would be better to stick with my current setup?
It would certainly be the cheaper option... And while the KH310 is a lovely speaker the KH120 is no slouch... If setup properly with a good subwoofer I should imagine the combination would perform to a similar level to the KH310....
