I can't figure out how you would use both of these in one room. the EP500 does such a good job I can't imagine an additional EP125 would make any improvment. It's a geat little sub, but, it's no EP500.

If it were me, I would keep you EP500 for your HT and use your EP125 in a home office or 2nd listening room.

Just a thought.
