I find them noticeably more dynamic. They can have a 'jump' factor like a really good box speaker. And they do bass really well. This is probably because they actually have a suspension unlike Maggies where the planar drivers are stretched tautly.

The Apogees had a suspension too and were likewise more dynamic.
However, you can get around some of the Maggie's stiffness at high excursions with gigantic power amps to eat the back emf. Stiffening the frames into a rigid form helps a lot, of course.
Analysis audio has had an add on bass panel option for their top model for quite a while. So I understand this new model has a different midbass/tweeter section and is actually designed as a 3 way?
"The Apogees had a suspension too and were likewise more dynamic."
No, I'm afraid not. Apogee's are no different than Magnepan's (in concept) with to regard to woofer "suspension." Both employ a stretched diaphragm transducer securely attached on the perimeter. This is unlike a conventional driver that functions in "pistonic" mode (or attempts to) via a proper suspension, relative to a transducer like a Magnepan that operates in the "breakup" mode at all times.
The Analysis Audio speakers are somewhat different in design but much more similar to Apogee/Magnepan than a conventional speaker. I get the reference to a "suspension" mentioned my hahax, but I think it's 'stretching' the definition.

The tweeter is a ribbon, not a planar. And the main driver has, I believe, a half roll surround. I got that from the importer who was a member of my Hi Fi club for years.
The Apogee driver is a longer stroke driver compared to the Magneplanar type of driver. I think the Apogee can move with less restriction due to its corrogation. It is tightly stretched in just one direction. Analysis have a soft perimeter around its bass driver and it alows more stroke than Magnepan. The Tympani IVa basses can only move 2 mm before hitting the magnets. The older Tympanis just 1.6 mm. That motion is not very linear.
Roger,
Yes, I understand but the corrugations of the Apogee drivers are in the same direction as the tensioning force. The static tension is less on an Apogee driver relative to a Magnepan and the excursion capability is somewhat more.....but they still have the same "suspension" mechanism, per se.
I'm pretty well aware of the differences between Apogee's and Magnepan's......I still own both. :)
Dave.
Is not the tension from side to side on the Apogee? There is no tension from top to bottom as it would remove the corrugation.
Yes indeed, only tensioned side to side. There are securing strips on the top and bottom, but those only exist to provide the weather-stripping damping. Those strips are secured with screws but left marginally loose on purpose.
Dave.
Exactly Roger.
You've only got tension in 1 direction to compare with Magnepan that is stretched in all directions.
And that is not all. Magnepan membranes in general is also restricted in movement by the tuning points.
What this does to the motion is obvious.Cheers!
The one who succeeded was the one who didn't know it was impossible.
