Can I test each driver in a Jubal L65

So here's the scoop. I'm pretty happy in my small-ish listening room listening to my Sansui AU-9500, SR717 with Grado Silver, and Magnepan 1.4's (refurbished.)
I have a chance to pick up some L65's and I'm curious to know how they will sound relative to the Maggies. I know that the L65's will require stands...
Can I check each driver to make sure no electronic problems exist? They sound great and the surrounds look good on inspection.
Thoughts?
