Klipsch La Scala half-wall corners?

I'm in the process of designing my finished basement project.  the basement is approx 36x36.   the wall that i'm planning to place speakers on has a large spot (17ft long) that i plan to put TV and audio on.   on the left side of the 17 foot span i have a 3ft wide egress window, and on the right i have an outside entrance door (3ft). 

i intend to pull the trigger on a pair of la scalas.  since they benefit from a corner for low end, has anyone built half-walls? or does the added effect require a floor-to-ceiling wall?   

im still going back and forth over the aesthetics of the half walls.  on one hand it will help define the space.  on the other, it would be nice to have unobstructed views (but at least the half wall helps that way).   

hopefully the link below is visible.  thanks again
