That they work as advertised for nearly thirty years?

Total cubic feet of displacement? Ah, not quite.

To what are you referring?

By design a planer rolls off starting at 40 Hz. Any planer.

That's planar . The larger Maggies, Apogees, and a few full range stats run into the high twenties.

...either you have either added a sub or someone is fudging their data.

I don't know why it is you find it hard to believe that planars do what they do. Maggies have been around for quite some time.

Magnepan specs

We all know that the Rad Shack meter rolls off below 50 Hz or so. You undoubtedly fudged as you saw fit it to get your numbers the way you want them too.

Thats what correction curves are for. The actual calibrated variance at 20 hz is 2.5 db.

10 degrees off axis, I seriously doubt it. Remember, rolled off highs sound subjectively better.

How little you understand how the Sound Labs panel is arranged. Unlike KLH Nines, Quads, Acoustats, Martin-Logans, Audiostatics, Staxes, etc., the diaphragm is held by a faceted frame that covers a ninety degree arc (they do make some 22 degree and 45 degree models designed for creating multiple speaker arrays). Looking from above the speaker presents a half cylinder. The panels in my Acoustats, however, were flat as a board as was the frame. There wasn't the slightest bit of curve to it. And yes, off axis happened quite quickly. Not so with the U-1s.
