This is our living room, so the speakers will be used for tv as well as music and movies.
An entry level (8 or 10 inch) sub from Axiom, HSU, SVS, Elemental Designs etc
Since this is for movies, I would consider the EP350 to be the minimum sub that should be consideredfrom Axiom. I hate to say it, but I was underwhelmed by the EP175 in Axioms 12x20 demo room. Even at full volume it gave no real rumble for scenes that had a ton of LFE (LOTR Bridge of Kazad Dhum). As far as other brands, you could probably get away with something like the PB10 from SVS (lots of value for the money).
The M22 is a great speaker as are the QS4/8. In side by side comparison I found the M22 + sub to be very similar to the M60.
