Scientific Fidelity Crowne Joule 24k Signatures

I found a pair of these speakers locally this week-end which I have been told were made in very limited numbers.

Designed by Mike Mahoney, 60 lb monitor speakers. Minimal crossover, Solen Caps, total statement piece. I believe they sold for over $6000 when new.

the deal I got even included the matching stands! I spent Sunday giving them a listen and haven't gotten them to "sing" yet. Even with their weight, and extended depth of the speakers, I cannot get very good low end response. Anyone who has owns or have owned a pair have some suggestions? Close to a wall? corner? ...they are rear-ported and I currently have them within the room, fairly far from side or rear walls.
