You could probably negotiate a lower price on these:

The killer might be the shipping?
For the price they can be a great intro in the ESL sound, which I now prefer over conventional speakers (except $$ unobtanium)
Decent, mid-level panels have superior mid/high/vocal performance that only premium upscale conventional speakers can deliver-IMO, of course.
I've been using the model this replaced with good results. The bass unit is passive but give acceptable performance-with a sub which you have, you're golden.
Do you have Magnepan on your list also?

Optimum placement calls for pushing them out in the room to appreciate what all the fuss is about with these types of speakers. That, and rear wall treatment/clearance from side wall.
