Here's another reason for 3 subs "if" you follow Earl Geddes approach...

There doesn't seem like much if a difference in the graphs going from 2 to 3 subs, in that link. With 3 subs there is a slight reduction in a null at about 45Hz and that is about it. This is just one example though, maybe another room would yield better results.
