I'm set to order a M60ti pair, VP150, and MS-8 pair. I'm having trouble deciding on the subwoofer, though, as I'm not sure what one considers in this. The room is 15x13ft with carpeting (if that helps), and we listen to music 60% and movies 40%. Is the EP175 a good choice for us, or would the EP375 be better? Or do you have another recommendation? We're not looking for floorshaking vibration but something to round out the sound of music and give some zip to movies..

Thanks.
