I would also endorse use of the Sumiko method. When using this method, it is surprising how much bass response changes with the smallest of placement change. That means that one could find a spot that at least minimizes boom while staying reasonably close to the current placement.
If placement change does not help, use of some form of equalization is the most realistic approach to removing a boom. At low frequencies, room treatments (bass traps) must be pretty big in order to be effective -- unless one is allowed to take up a lot of space in the corner, this is not that practical in situations where room decor and space utilization are a big issue.
