Agree completely

Which is why I've always loved the midbass on the Tympanis -- almost-dynamic extension and slam, but with a naturalism that omnidirectional woofers don't have.

I've come to believe that one of the main reasons for the naturalism is that dipole woofers, when oriented parallel to the front wall, don't trigger the horizontal and vertical axial modes. This is spectacularly apparent in the impulse response graphs near the bottom of this page. When you toe in the dipole 45 degrees, most of the magic is gone:

So the Tympanis had an advantage over dipoles that don't allow you to move the woofer panels independently of the tweetes and mids.

With dipoles, you can also get partial cancellation of the remaining depth axial mode if you sit the same distance from the rear wall as the dipoles are from the front. I used to do that with my 1-D's to good effect.
