A few years ago when I was using the EPOS 11 in a HT set-up, I spoke with Michael Creek (Creek Audio; EPOS speakers) and he said to try to purchase a used EPOS 11 and use it as a center speaker. EPOS now makes a center channel speaker , that is voiced to their new mini-monitors, ELS 3. It retails for $300. I have owned both the EPOS 11 and ELS 3 speakers ... they are not identical, but close enough in voicing ... you should be OK.
