Not a 12 but a 10, and mine has built in tilt back. Used to do a 12 that didn't tilt, though. Stuck a 2x2 painted black under it and left it on the floor. But you can elevate it some without losing floor coupling. Doesn't really matter for floor coupling till you elevate it like 2 1/2 feet. If there's a wall, I like it as close as possible because you can get cancellations at certain frequencies depending on how far from the wall.
