2-way and sub crossover not matching, does it matter?

So, the title isn't that great but I'm going to be purchasing a pair of 2-way speakers soon. It has a 7" mid/bass that does produce some pretty damn good sub bass. On the secondhand market I've come across a pair of 10" "subs". Now, it's a sub that is designed to be bi-wired with their matching speakers (the speakers these are designed to go with have a toggle switch to crossover at 80hz).

Been trying to keep the description fairly straight forward, as the speakers I'm going to be purchasing soon don't have that crossover, does it matter if both the speakers and subs are producing 80hz and below?

I'd also like to mention that a part of the reason for looking at these particular 10" subs is that they're in a fairly significantly large cabinet that would make a great stand for the stand mount speakers I'm looking at. Very similar wood veneer and would simply put make nice looking function stands.
