Welcome Tigger,
Most solid state receivers will have no problem driving Axiom speakers, they are very efficient and easy to drive. Many Axiom owners use Yamaha as their receiver.
What are the dimensions of your room, I know you said 400 sq ft, but dimensions will help.
The speakers you listed would be just fine. The Q series surrounds will do a much better job for surround effects during movies. They also do a great job for music, in my opinion.
Some people like to use bookshelf speakers for the rear channels, but I use 4 Qs8's all the way around.
In my opinion, Axiom speakers would be classified as an audiophile grade of speaker. To me, JBL and Polk are more of a "retail" chain store type of speaker. Axiom really is in a better league.
