I'd also put JL Audio ZR's and Morel into that mix for consideration.
I was running JL XR's from Slash series (JL) amps, Alpine front end and 10W7 sub.
Am about to go for the new install in the Zed but not sure how to go - probably still JL front end (through an H701), JL amps and 10W7 (I love that sub, gave me 19/20 on sub bass a couple of times! ) - main reason being I can't see anything having moved on generally to better it. The Focal Berylium stuff is hugely pricey for what you get IMO, and would go Genesis before that.
Focal / JL / Morel / Rainbow / Genesis would give you a great sound IMO, and all are proven in competition.
