What frequency do I crossover subs

Let your ears be the jugde. When it comes to subwoofer integration there are no absolutely right or wrong solution even with DRC. It is up to you to decide how your bass suppose to be sound. You have to play around with sub placement, crossover point, phase, delay to find you ”near perfect” setting. Just my 2cts

Martykl,

I do agree with you that the scientific method or DRC does help getting to the goal faster but the final jugdment is still by ears.
