That's not necessarily the case. With the subs' crossover settings at 60 Hz, you will likely influence the the nulls upto 120 and, maybe, 180 simply due to overtones and room coupling. If you're using RTA software, it'll be helpful to find the optimal crossover point to mate the subs with your mains.
