Welcome to the Forum.[] Lot's of knowledgable folks here.
You are going to love your new 7's. I've had mine for a few years now and love them.
Bi-wiring is a bit of a controversial subject around here, I myself am of the belief it's a waste of time. Others may disagree.
Consider not only upgrading of your Jenson's but your receiver as well. The RF-7 is a speaker that likes lots of power. I have a B&K 200x5 and they sound great with it. The upgrade bug will bite you like it has the rest of us.[]
Anyway, welcome again and happy listening.
