B&W CM7 Impedance Curve

This is a shot in the dark, but here it goes. Has anyone seen an impedance curve graph for the B&W CM7? I contacted B&W's U.S. operations and they told me that it's not available. That leads me to believe it looks like the Swiss Alps, and also makes me angry considering most other companies would provide that information right on their web site. I wish I had been wiser in my choice of speakers. What do they think, someone's going to crack the code on these not too bad speakers?
I've never seen an impedance curve on any manufacturer's web site. B&W is the only (non-pro) manufacturer that I know of that lists THD specs for many of their speakers. I congratulate them for that.

Regardless of the speaker's impedance curve, if you get a reasonably smooth frequency response above 300 Hz and the typical treble roll off above 10K Hz in your room things are good.
Ask 'em about phase angle, too. That should raise there hackles.

phase is arguably more important that impedance. And a hi phase angle at the same frequency as a low impedance dip is worst of all.

a 45degree angle will reduce apparent power by 30%, not at all trivial.

some amps, mainly tube, simply do not like such loads.
Sound & Vision magazine reviewed and measured these speakers.

Thanks Layman. I read that just the other day. The review doesn't tell me a heck of a lot, probably because I don't know enough about it. I'm trying to figure out if I could make myself happier with different speakers.
From the review in Sound and Vision, I think Tom N. sums up the CM7 well when he said: "This system is attractively styled, but its measured performance was mediocre."

The frequency response of the CM7 is poor. He measured 84 Hz - 20 KHz +/- 5dB. A good response would have a window of maybe +/- 2 dB. There are plenty of speakers in the Stereophile archive that will show you a good response. For example, the Revel Concerta F12.

You could definitely find better performing speakers. That may or may not translate into you liking them better.
Thanks Bob. Why is B&W's published frequency response not coincide with Tom N's findings? Do the manufacturers butter it up a little or do they measure it differently?
Donjr, it's possible that B&W measured on a different axis (horizontal and/or vertical) than Tom, but unless they differed substantially you'd expect the response to be closer. Maybe sample variation could account for it -- Tom had a sample that didn't meet the reference. But where's B&W's quality control?

The only thing that really matters to you is the sample you have and how it measures in your room. If you haven't tried measuring the response in your room, I recommend it. It's a good exercise and the results can be eye opening.
I ask this without any attitude behind it: Why do you need or want to know ?
