Well that's a bummer that you've been dropped you as a stockist, because you've obviously done a great deal to get people interested in the monitor.
I was thinking the other day that the problem with many of these new speakers especially one that has proprietary parts, is that down the road when something eventually fails or gets broken, will there be the support to get it fixed?
Experience has told me you might be left with something difficult too repair or un-repairable. If you look at what has happened with the Opal monitors, you can't get them repaired, yet Opal is owned by RODE mics, a pretty big company. Same goes for Dynaudio, eventually they gave me a new pair of monitors because of all the hassle i had, but what if your monitors fail after 5 years and your unable to get a simple part to repair it?
This is where ATC still has an advantage i feel.
Sure. But if you can describe and understand something, you can also measure it (and vice versa). If something sounds tiny and compressed, it is due to nonlinearity of some sort, so either measuring distortion or resultant air pressure variation as a function of input power should show it.

seriously, those measurements are a insult to KiiI dont blame them in the slightest! Plots with no scale markings and huge great troughs and peaks do them few favours.
A loudspeaker would be distorting massively before you would ever hear any distortion from the amplifier driving it...
Note: assuming the amp and speaker were correctly matched.
No active hifi speaker will ever be as dynamic as a horn speaker, or provide better dynamic contrasts, or scale, or resolution.
The problem is people dont do any of this. The most one ever sees is a simple response plot in an unknown room. Far less use than even the anechoic measurements of the 1960s and 70s, which were at least of some interest. Ive seen nothing in a magazine that would explain via plot, graph etc why a huge horn with 15 bass sounds so inherently different (bigger, easier, freer, more alive etc) to say a little ported or transmission-line slim floorstander or whatever that may actually go a little deeper on paper.

If an amplifier momentarily clips on music peaks, you can most certainly hear the distortion.
But on the other hand, active speakers don't have the well known deleterious effects of passive crossovers either, so a bit of a swings and roundabouts situation perhaps.
Bass aside, rolling off at 60 Hz, do you have any speakers with bass?
H yes point taken I will add all the parameters in the upcoming article.
The Dutch&Dutch enjoy being placed close to the wall behind them you can adjust their response for the rear and side walls from their app.
I have them now 50cm from the rear wall although they could go to 10cm, sitting in an equilateral triangle with the microphone placed at my listening position .
I will compare to traditional active monitors placed in the same positions.

Not huge extension no, large high eficiency speakers don’t tend to dig that deep, but I guarantee both the Lockwoods or La Scalas will sound more like a real bass instrument, piano or whatever than any amount of waggling little tiny drivers around in little boxes will ever achieve. This being Graham’s point upthread that started this whole thread divert. He is right. Measurements are only any use if one understands what to measure, and with respect you have a very long journey ahead on that route, as do the magazines etc. Simplistic ‘quantity on a line’ isn’t even the half of it!
The Dutch and Dutchs are designed to be placed close to a wall, and their rear facing drivers positively exploit the boundary effect. But then that probably means they need to be against a solid wall, rather than a plasterboard one, and not in front of a window which will let low frequencies go straight through. In most of the pictures ive seen of your room, you have the speakers with a glass bay window behind them. Where do you have the 8cs?
Come off it! Bass extension aside they are no better than I’m getting from a 1961 valve amp and inexpensive late-70s sealed-box mini-monitors!
PS Note the 5db scale, i.e. twice the resolution of Keith’s! Note that I published it too!
Keith, what did the customer think of the comparison. Could you post some subjective comments. Having heard the Kii's it may help to see where the 8C's sit.Yes they work very well against a wall, bass output is adjustable, just performed a Kii/8C comparison for a customer, I will bring the 8Cs down into the same room as the ATCs and measure both.
