I am using four of the older B&W DM302 all around with the matching CC-3 center. I also use a similar Onkyo Receiver. Sounds great to me. Both the DM302 and DM303 have been highly rated, and have won various audio awards
Bass can always wait; just set the receiver to "no subwoofer". I am using a REL Q100E sub. I will say that having good quality bass will bring the system up a couple rungs. The DM303 and 302 are very nice, and they won't be outclassed if you get a better quality subwoofer, once you save up some more $$$.
