CORNER placement subwoofer(s)

I am trying to make my music room more people friendly.  It is 12.5’ by 19.5’ by 7.5’ and somewhat “live” but tamed with Michael Green Design PZCs.  Walls are plaster.  Two are outside walls including the front wall.  Recently purchased speakers that can be placed against the wall or wall mounted (LaHave CFR).  Thinking of adding subs to fill in the deepest bass BUT they would need to be placed in corners to keep the idea of making my room more like the living room it is.  What is available in subs designed for corner placement??  I could do one or two.  I have owned REL and Rega subs in the past but they are long gone from my home.
