No, if the towers are set to large, ALL the bass in the L & R channel is going to the tower.
But at the end of the day, you paid for the system and should set it up the way you like it! It may be that the bass response at your seated position is not ideal, so moving your sub could help. Or it may be that you just like more bass, and that's okay, play your speakers large.
Unless there was an error with YPAO or poor placement of your sub in relation to your chair, running the mains "small", and setting the crossover on the sub itself to (bypass), should yield the most accurate response. But you'll note I use the word "accurate" and not "immersive".
How big is your room? Open to what?

Agreed. All LFE and the re-directed bass.
And: This can also help improve overall output, since the receiver power is not used reproducting low bass tones, which are shuttled off to the sub.
