I found that flipping it upside-down angled the speaker too much for my space--I sit about 12 feet away from the speaker. To overcome this I simply removed the rear rubber foot of the speaker stand--there are two more in the front that I left in place. That gave me a slight angle that seems to have worked well for me.
