There is a reason I have my 12inch subs crossover at 60 hrtz and my 8 inch woofers crossover at 120 hrtz, then my mids pick up above that. It gets muddy as the speaker cone gets larger and the frequency goes up, sure the speaker CAN but should it ever produce above 100 hertz, hell to the no.

Are you trying to refer to 2nd and 3rd order harmonics? Typically, those issues are much more dependent on your ability to integrate the sub with mid-bass and mid-range. You should check out pro audio.
