I'm working on setting up my gym (13x14 room) and currently have M3s in there. I tested it out using my EP500 as well as an EP350 (borrowed from my other rooms) and both sounded great but no noticeable benefit to the 500 over the 350 in that size room. I definitely want a subwoofer but since it's a gym would prefer not to buy a 350. Would an EP125 be noticeably worse than the EP350 in that size of a room?
