Where do you put your sub?

mines up against the wall under my desk... also a good foot rest... lol

but you know move it around see where it sounds better. Mine gets kinda muted by the inch of wood that makes up my desk lol

Floor is generally accepted as the best place. Because a sub is low level frequencies that affect your body more than your ears, it shakes the ground. At least thats my logic.

Mine is on the floor to the right of the video source.

A corner is a good place.

I originally had the driver facing the wall, about a foot away, but it caused the bass to be so overpowering that I had to turn the driver to face the room.

Make sure, if you have a ported box, the port should be at least a foot, if not two feet from a wall.

I strap mine to my back.

Nah it's at my feet on the floor

Mine's under the desk which I know isn't the best place acoustically. It's where it's least conspicuous though so I'm willing to trade off.
