I would say yes, if you don't want to ruin the rhythm and pace of your music. Placing subs in the corners in a high end system will result in more bass QUANTITY, but it may be a bit bloated and slow.
Dr.Gizmo Harvey Rosenberg wrote some stuff on this a few years ago, suggesting putting your subs on stands and having them in a near plane to the mains (you can probably google this article, good reading!)
I have adopted this set up with my Audio Physic Virgo speakers and dual Sunfire subs, with the subs just slightly behind andto the outside of the mains, and my system has never sounded better.
Enjoy!
