I would love to build an open baffle speaker using 2 GRS 15" drivers in parallel along with this q100 driver. I'm ok experimenting but the largest purchase (besides the drivers) will be the inductor. Is this a value that you can take a stab in the dark and work the rest of the crossover from there, or do I really need to nail that value?
Decent amount of info on the speaker/driver here

Do I start by just plopping all the drivers in the baffle and measure and decide what the values should be after measuring?
For instance it looks like the q100 woofer has sensitivity of 87db not sure about the tweeter but I would start by using the stock xo so I would assume the same sensitivity with the xo. The GRS 15" has a sensitivity of 87dB 2.83V/1m, Can I makeup the 6db baffle step by adding the second woofer in parallel. My lack of knowledge is probably starting to show itself 🙂
Would the spacing be too far apart to have the Woofers stacked if I crossed at 400hz or so? (Don't even know how you create an analog XO to crossover at specific frequency or at what slope. I saw some suggesting a 16guage 14mH Inductor for the woofers. Does that make sense?
I wan to get started and not sure where best to start without throwing money away.
One other thought was using my 2x4HD mini DSP and bi amping to keep the q100 analog stock XO and using the MiniDSP to blend the woofers with separate amplification.
I have Umik and REW for measurements and know enough to know I don't totally know what I'm doing.
