If the speakers are set to SMALL in the AVR, there will be as, at the least, rerouted bass from the front channels will be sent to the subwoofer. But be aware that, depending upon whether or not your TV can pass 5.1 via its digital output, and whether or not the input source material is 5.1 to begin with, you may be dropping the LFE channel (the ".1" of 5.1), altogether. If the TV only passes a 2 channel downmix, the LFE channel will be dropped from 5.1 material. If the input source material is only 2.0 to begin with, this would not be a concern.
