The best place is trial and error. Nobody can tell you without being in the room.

 Try the top/left corner of the drawing.  Also, as you experiment with different sub positions be sure to recalibrate(and tweak the distance setting / phase setting each time you move the woof.

Fuzz posted a link to an article that has the advice I always give. Rather than schlepping the sub around the room to try different spots, put it where you'll be sitting and YOU move around to find the best spot. This will identify the correct acoustical relationship between you and the sub. Works every time.

To do this 100% the correct way, you need to get your sub up to ear level.

Like Robert_J says...

 

Sub crawl(which is what you call it...and what I've occasionally offered up) is a bigger PITA than it sounds.

 

How many people here can put an SVS 13Ultra(either version) ear height?

 

You'd have more success buying one of these things...

And rolling it around the room.
