I have the Ref 1, which have taken the place of my Harbeth Super HL5 Plus in my main system. They sound pretty big on their own. I have 4 subs in my system and one day turned them off and forgot to turn them back on. I noticed something was different in my system, but it took me a bit to put my finger on it, they do that well on their own. I haven't heard the Ref 3 but would expect them to play even bigger.
