No I havent felt the need to, it really sounds great were its at . Its very pleasing to say the least . If it was a lighter sub or it wasnt giving me the results I was hoping for I'd try different locations. But im really really happy with its performance were its at

oh and actually were its pointing is towards the main seating positions and behind that is a open hallway probably about 30 feet or so and the ceilings are 10 ft I beleive until you get to the end of the hall and its cathedral ceilings . For the size room this ultra hits hard
