"The vertical bi-amp will not work with the Thiel CS3.7 since it only has 1 set of speaker inputs."Yes it's very easy to do, "if" the owner or a friend has a little knowledge.
Check out bettlemania's system on the virtual systems ,
he bi-wired his 2.4's .
Once again do not bridge into these CS3.7's, you'll gain loudness at the expense of sound quality and reliability.
This is stretching it, but bridging turns what was a good quality amp into a more powerfull P.A. amp.
