Hi It's my first post here. I have inherited a Denon AVR-87 and am trying to match decent speakers to it. The room it is in is 15X13. After hours of research on the web I have a headache, but learned not to go with Bose (?), which I actually had my eyes on. So, what would your guys' advice be foe decent 5.1 speakers within a $800.00 range? Any advice will be much appreciated.
