I want to close by saying their are some on this board who feel that we can't rate low cost speakers as 5's. The Axiom Audio loudspeakers are a solid 5. Axiom makes a very good speaker and they could charge three times the price if they put a fansy cover on the front of them and had lots of advertising gimicks. It has the ability to hook up seperates unlike the Onkyo 575x and you need that ability. P.S. Don't be the fool that goes for Sony,JVC,Kenwood,Bose or Paridigm and take your time and audition and read through reviews carefully.
Acoustic research is plenty fine enough.
