From Mapleshade store's subwoofer advice page:

Quote:
• Always fire the subwoofer driver left or right, not directly at you or down into the floor. If the subwoofer is off center, then test left-facing versus right-facing to see which sounds better. If your subwoofer is designed to fire down, set it on its side with the driver facing left or right. Be sure to rigidly mount it to the floor or platform as per the second bullet below. You’ll love the increase in bass articulation and clarity.


Gotta love it.
