I saw that review, too, and at first I didn't quite know what to make of it. MC has been reviewing stuff forever, but that review didn't square with what I hear and measure from mine.After a little thought, though, I believe I know where the trouble lies. The biggest problem with these speakers is that they take a LONG time to run the woofers in. Out of the box, mine were 18db down at 63hz, and it takes at least a hundred hours of hard driving to loosen them up. After three weeks, mine were still down 6db at 63hz. That's why a lot of people have been turned off on them in showrooms--they do sound brash before they are broken in, and I think the process takes longer than most dealers appreciate. Most speakers in a dealer's showroom get very little time actually producing music, especially if the dealer has many different speakers to demo. They may get a few hours of actual play at loud levels in a week, and probably less. I know that my local Sound Advice has speakers that actually get driven by music no more than a few minutes a month.
It looks to me like the midbass hump that MC observed probably means that his speakers weren't as well run-in as he thought. To get more bass response, he placed them too close to the rear wall (he had them set up a foot from the rear wall, which is much too close). This probably overemphasized the midbass, and it also would have degraded their imaging--MC called them fair to good in that department, while mine beat hell out of the electrostats I used to own.
In my case, in an ordinary carpeted living room which opens behind the listener into other open space, the in room response of the Celius is much flatter than what is shown in the Colloms review, both in bass and midrange. I can't speak to upper treble because I'm an old fart and my hearing is shot above about 16KHz. I don't have the equipment to measure impedance or phase angle, but I have to wonder whether those weren't affected in the review by lack of run-in of the drivers, too.
Bottom line for me is that these are tremendous speakers, very emotionally involving, full of life and air. My wife, who has never been particularly interested in or impressed by earlier versions of my system, was stopped dead in her tracks when I put on Tapestry the other day, and actually sat down to listen with me. That's the acid test.
