speakers for my yamaha rx-v1700

Have my avr set up in living room, planing on 3.1 set up and bi amp fronts. Room size is 22x13, with listening area in middle of 22 foot wall. Floors hardwood with larg area rug. Plan to have speakers about 7-8 feet apart and listen from 11-12 feet. looking to go full range if possible without upgrading front end...any ideas? amp upgrade not an option at currnent, but may be possible in future. I guess the question is whether my receiver's amps are sufficient to get good sound from a decent speaker...Was considering KEF IQ series, MA RS6 and Dali ikons. Kind of new to all this

FWIW, was running 5.1 with B&W LM1 and a small CC3 in a smaller space

Thanks for helping a newbie out
