What if in your room, those super main speakers are not flat down to 40 Hz? Let’s say they show a big resonance bump at say, 60Hz, you might want to take advantage of crossing them over above this frequency and using your flexibility in sub placement to avoid that resonance at 60Hz.
That is why I prefer to know how my room measures after I have done the best I can with main speaker placement. I can dial in my sub much better with that data. My ears are not as good as the microphone.
Good luck no matter what you decide to do.

Thanks for the advice. I may be misunderstanding the point but in my case the sub supplements the main speakers (which will continue to be used full range). Therefore if there was a bump at say 60hz increasing the crossover on the sub would simply reinforce that bump ?
Regarding the roll off point wouldn't that be determined by the speaker more than the room. I appreciate there can be peaks and nulls but I would have thought that a sub is a fairly blunt instrument - wouldn't room treatment (bass traps etc) be a better solution to deal with that kind of issue ?
