No, unless you have the speakers arranged like so:

For movie surround, the front speakers should be placed at the edges of the screen, toed in to face the central listening location, and the tweeters should be ear height. The center speaker should be placed behind the screen (when using projection) or over or under a TV, and as close to ear high as possible. Side channel speakers should be placed high on side walls, to the left and right of the listening position, equidistant from the front speakers and the rear speakers. Rear channel speakers should be placed high on side walls, slightly behind the listening position, and should have a normal high-quality monopolar construction.

And that's for movies. For music, 6.1 doesn't exist. http://en.wikipedia.org/wiki/Surround_sound says so.
