I have a REL sub and it did not work in the corner of my room- boomy wobbly bass. Ultimately, the sub worked best when it was placed on the same plane as the speakers.
I agree with the above post on not having enough sub for the room and using corner placement as a substitute is not a good solution.
Once you have enough output, though, you will most likely get better bass using two good subs versus one really good sub. Most people do not understand that it is not always about output, but rather equalized sound pressure in the room. Yes, I've heard all the theories about bass not being directional, but to my ears stereo subs work better.
