I would go towards getting the EP500. it will give far more room pressurization than you could get from a dual EP175. I have two of them for a room of about the same dimension and its overkill for what is needed, but it does a wonderful job of offloading the bass from the mains and gives an impressive sound.

If you go with the larger unit, you not only get a deeper sound but if in the future you want more, then you have a path forward, where the dual EP175 really is more a very small room unit and never going to compete.
