"Since the output of the receiver is small,..... I feel that you don't need a subwoofer if you have a good pair of floorstanders. "
A sub takes the power away from the main amp, and of the amp is small as you say, then all the more reason you need a sub.
Note that many, or most floorstanders don't have an appreciable output where the sub would be in any case.
