Thank you EarlK!
I will use the original schematic for inspiration/a starting point/sense check my design.
I have already measured the 2445's on the 2385's freestanding and IMHO they perform great, certainly better than I expected....
I've been able to mock up a crossover that gets them nice and flat on axis with a theoretical 800hz(ish) highpass....
But wanted to see how JBL implemented their approach - learn from the masters.
