Is there a way to have REW calculate potential frequency and slope curves to achieve desired target level. I used the Jazzi chart to import house curves into REW. I ended up with 5500 Hz BU2 on the left tweeter and 4000 Hz LR4 on the right tweeter. The target was a 3500 Hz HP LR4 electrial crossover. I used a lot of trial and error to come up with those numbers. Both sides match acoustically. Is there a faster way to achieve the end goal of finding the proper frequency and slope?
