I voted “Not really much value in it.”
I have gone for weeks running just my M80s because I turned off my EP500 and forgot to turn it back on until something I know well, usually a movie, is played and I realized something is missing.
That’s not to say there isn’t a noticeable difference when the EP500 is on it’s just not IMO a very big difference. In other words had I purchased my M80s strictly for music and not also for movies I wouldn’t waste the money on getting a subwoofer.
Much of my music listening at home is while I’m up and doing things. Since I’m moving around I don’t get any great benefit with most music using the surround channels and because of horrible room modes that can only really be effectively corrected near my seating I find the subwoofer to inconsistent as I move around the house.
