Current System:

Speakers: Polk Rm6900
Receiver: JVC Rx-D702

I recently moved my home theater to a larger room (22 x 24) and need to upgrade my system. I want to move my front bookshelf speakers (Rm6901s) to side surrounds and my current side surrounds (Rm6801 sats) to back surrounds. I am looking at Rm7400Ts ($1000/pr) for my new fronts. Is this a good choice? How much improvement would I get with this upgrade? Any better suggestions?

Also, with frong speakers this large should I still connect receiver to sub and front speakers to sub with fronts set as large and sub off? What about crossover setting on receiver? I could also use help with sub volume and frequency setting
