Just came across this post so I thought I'd add my own info on the topic for future reference.
In regards to the Dyn's bottoming out, there are a number of references to this.

plus a few more, I did not look too hard.
I believe all the models mentioned, the 52se's, 1.3's, 1.8 and the 3.4's use the same or simliar driver.
The reason I know is that I have the 1.3MKII's and can get them to pop (bottom out) at loud volume with fast deep bass if they are run full range.
I'm running them with a Teac VRDS-20, Bryston pre and 3BST.
Crossed over with my Velodyne I can run them as loud as I want without strain in my 15 x 25 room.
