Ah, more of a 2 channel system. As Fred mentioned I was refering to the receiver's sub setting, but yours appears to be very limited. I am not familiar with the 2150 to know what that switch does.
off to download the manual. I'm back
I would set that sub switch to bypass for now until you have a sub and even then I think I would keep it in bypass and use the subs filter; set at 40 to only have it play the lowest notes the M80s are not all that capable of playing. I suspect that switch cuts out the signal below the selected frequency so the mains wouldn't get anytihng below 60 if you were to use it
There also appears to be a speaker eq setting that could boost the bass in the 50-60hz range you could try setting that to see if that gives you the desired punch from the M80s
