From the picture it appears you could go with the placements indicated in option one w/out having to ceiling mount. If that's a wall by the right surround, mount it there. For the left you could do some sort of twisted wall mount as afforded by a flexible mounting device like Axioms Full Metal Bracket. While you may not be able to get it fully sideways, it would be close.
In fact, I think I'm going to do something like that - looks be damned.
