The above posters all agree with me ;-) so I would just like to add my 2 cents and hope it helps.
Your room is quite big and so is your budget. There are some darn good full-range speakers available for what you have to spend, including my Meadowlark Shearwater Hot Rods. They image beautifully. You can get center and rear channel units from Meadowlark too. The Shearwaters go down to 40 Hz easy, maybe lower, but I didn't get that performance out of them till I upgraded the power cord on my Klyne preamp to an Ensemble Powerflux.
Your Attraction has a great preamp by all reports, so it deserves a premium cord if it doesn't have one already.
Getting a musical system match with a sub is a headache. I wouldn't consider a sub unless I knew for sure the rest of my system was already giving its best.
