Focal Aria 906 in 20x20 room


My room isn't exactly square as the subject indicates but it is approximately 400 sq/ft with 8ft ceilings.  I'm looking for a bookshelf to run dual purpose for home theater and stereo.  I don't want a tower speaker as I fully intend to run the setup crossed over to subwoofers at 80hz for both music and HT.

Thanks for the response.  I was kind of leaning that way but was trying to see if I could pull off monitors with a good subwoofer.  Probably better safe than sorry.
