It says something about the loudspeakers and about his room"The Kii THREE’s are the first loudspeakers to come into my room where I did not feel the need to apply external Digital Signal Processing (DSP) to smooth the frequency response." - Mitch
That says something, considering his involvement with corrective measures.

I don't think so. The sound of these speakers is less affected by room acoustics due to their controlled radiation. Perhaps some rooms are so bad that even the Kii's will not be tolerable but none of us have rooms like that.A co-incidental match??
I though the speaker already has DSP. Maybe no reason for DSP done twice. Perhaps he misspoke.I don't think so.

Hifi shows are weird things, probably best viewed as if they are some sort of bizarre art installation, go to be amused.Oooh. Free to the public. I can afford free.
It's a very interesting review, and the 8c tease at the end is also very interesting.
The one thing I don't follow is given that these are flat in an anechoic chamber, and the downward slope in room response is meant to be what you get when you put a flat speaker into a room, why do they need the treble attenuating? Should they not naturally slope down.
That is what I assumed from his statement "....I did not feel the need to apply external Digital Signal Processing (DSP)...."I believe he was referring to room-corrective DSP.
That makes sense, but, the 8c's also are flat on and off axis, but slope down in room in Mitch's measurements, so I'm back to confused.The typical downward-sloping room response is a combination of room materials and furnishing tending to absorb more high frequencies and speakers tending to become more omni-directional as frequency decreases (ie downward-sloping power response). The Kii’s have very constant directivity almost the whole way down the frequency range, so their power response will not contribute to this effect, hence their tendency to sound brighter than what listeners are used to in-room.

P.S. I'm sure Mitch responded to my question above but I cannot find his response now, odd.
It occurs to me that we are shown horizontal polar responses, but not vertical, I wonder if they are very different.Yes, you're right.
HF absorption by room furnishings alone may be the reason for the downward sloping steady-state response.
It could also be partly due to the Kii 3s having a downward-sloping on-axis response (according to Stereophile's measurements anyway - note that the other independent measurement I've seen does not agree with Stereophile's, which is another minor mystery).
It could simply be that the power response of the speaker is less of a factor than I'd presumed it to be, in Mitch's room at least.
Or that there is some bipole-type behaviour by the Kii 3 in the low to mid frequencies that doesn't show up on their measurements (which only show the +90° to -90° polar response).
I wonder if @mitchco still has the Kii 3s to take some quasi-anechoic measurements in his listening room, particularly the rear 180° of the speaker?
Or if you have a theory on this yourself Mitch?
He chose to delete it, reason unknown.That makes sense, but, the 8c's also are flat on and off axis, but slope down in room in Mitch's measurements, so I'm back to confused.

FWIW I didn't see it as intrusion, I intend to respond properly to it but serious life stuff kept getting in the way.Yes, sorry guys. I did write something and then deleted it, as I did not want to intrude. I did post a response here: https://audiosciencereview.com/forum/index.php?threads/dutch-dutch-8cs.2299/page-33#post-100289
