Ok. So, here's a comparison of what's in the specs for each:
..SW.......Room.Resp...Max.SPL..Crossover
EP125.v2...25.-.150......114....60.-.120
EP175.v2...22.-.150......116....60.-.120
EP350.v3...18.-.150......118....40.-.150
EP400......17.-.150......116....40.-.150
EP500.v2...17.-.100......120....40.-.150
EP600.v2...15.-.100......122....40.-.100
EP800......12.-.150......125....40.-.150
Not sure what this chart is going to look like, but here goes nothing. According to this, it looks like even the EP125 would probably work ok for my living room.
