Currently, I have an EP125 in my apartment (11' x 15' room) and my listening is about 95% music. Thus far, I've really enjoyed its tight and accurate response. In a larger room, it might have a tough time keeping up. Sadly, living in an apartment means that I have not had the chance to find its limits, but I hope to be in a house some time next year. Honestly, with a room of your size, I would move up to the EP175 to be on the safe side. Hope that helps a bit.
