Conrad Johnson Synthesis Speakers

Hey! My Pops is letting me inherit his old CJ Synthesis towers, sort of a family heirloom if you will.

Here they are:http://www.dropbox.com/gallery/5928773/1/speaks?h=8aa51a

Does anyone know what model number these are? (LM200 I think?) and what I should use wattage wise to juice-them? or any other information that might be good to know?

Thanks for any info!
