Not at knee height inline with your knees as though your knees intersect the imaginary line beyween the L&R surrounds.
Its certainly worth trying, its worked well for me in a few different narrow rooms/layouts.
He'll still want to turn them down a bit because they're so close. They'll almost work like wides rather than side surrounds...it fills the sound hole between the front soundstage and rear surrounds.
I stopped doing this when I got my Hp's. The side surrounds and fronts were competing, the front soundstage filled the room and around my seat on their own.
Now all my surrounds are turned way down (sometimes off all together).
