Do not choose speakers by AVR ... First choose the speakers you like and then find an AVR or AMP to drive them ... Now that both of you have purchased an AVR....
Better listen to the speakers based on the choice of music u listen to , room size , budget , acoustics , 5.1 speaker package or build 5.1 with FS / BS and other combo..
Tons of brands available in the market....... its a long journey to deicde on the perfect pair of speakers....
Go thru the speaker review threads by Rana_kriti, mpw, denom,frank_mehta and sonosphere .(just to get an idea) ..
Good luck in the speaker hunt.
