Of course, I was referring to the S2v2 regarding aluminum woofers.
Soundstage doesn't do spectral decay plots, so I can't see how you can look at what they measured and decide whether or not the cone has any measurable breakup modes.
You seem to be one of those people who changes everything. Don't worry, I have a wife who does that, too, and she's a great person. First of all, I said Ididn't see any evidence of significant resonances in the measurements Soundstage did for the S1, v. 2. I might also mention that I searched the Stereophile review of the S2, original version, and did not find the word "congestion." More importantly, the review does not imply congestion. We have the original Paradigm Signature S2 speakers, and I have never heard anything from them I would call congestion. Would the newest iteration be better? The review of the S1, v. 2, in Soundstage indicates they measure better, with a couple of the small anomalies in the measurements of the original version gone. But I not currently looking for new speakers--a subwoofer with more output below 20 Hz, perhaps.
Now, as for those pesky resonances, you could check the impedance plot to see if there are any little glitches in it. And you could check the FR and dispersion plots to see if there are any anomalies that go across all of them.
I don't want to make too much of the fact that monitors from PSB, Paradigm, Kef, and some other makers seem to be able to play louder than many others without undue distortion or limiting. Someone mentioned the Usher Be-718, which seems to be an excellent speaker. It certainly measures very well. I haven't heard it, but for all I know, I might like it as well as my current speakers. However, Soundstage showed distortion at 90 dB for the Be-718, but not at 95 dB. How important is it? Probably not very as they probably can play loud enough with clean sound. Actually, I would not expect the speakers mentioned in this thread to have congested sound in normal use. I would expect that to be a placement issue with speakers of this caliber. That's the nice thing about the better speakers in this kind of price range: most of them should be satisfactory. There are surely some mediocre speakers in this price range, but they can be avoided with some care.
Sometimes dealers do not display speaker to their best advantage, and often enough, I have had to request that they move them out in the open.
Some years ago, I spent some time auditioning the Ethera Vitae speakers in the manufacturer's home. They sounded great on a wide variety of material. They are probably a bit large for a small room and I don't know the current price. They do make a smaller speaker called the Seraph but I have never heard it. If one is looking for something off the beaten track, it might be worth considering.

I'm listening to The Famous Sound of Three Blind Mice samplers tonight, and they sound great. They would probably sound great over all speakers mentioned in this thread. I got them 20 odd years ago, and they can still be bought but the prices are pretty high! Whew!
