"I was more curious as to setting the crossover in the dsp if they should be set at the same frequency or one higher or lower than the other. Like 1700 tweeter. 1500 mid"
We don't know that, you need to measure and then adjust with the DSP if needed.
Anyway, if you flatten the response of the driver(s) (before xo slopes applied) at least 1 octave past the xo point (with capacitor in place), then you don't need to set the low- and high-pass to different points. If you want 1600Hz, just set to 1600Hz and then adjust the timing.

Yes of course but it is common that crossover points in a dsp are separated like that? I’ve only ever seen peoples crossovers be set for the same level. Never apart.
^^ elijahscott, For sure, do what ever it takes to make the combined response best possible, that is what is needed and wanted, good acoustic output from the whole system as a whole. The drivers have their own responses and then there might be some acoustic stuff you want to compensate like baffle step or resonances. What DSP filters is needed to achieve is irrelevant as long as it doesn't kill the drivers.
To get nice acoustic crossover it might require very weird stuff in DSP to make you didn't anticipate before hand. I think it is quite easy to tweak the xo in the simulator, just don't assume anything, add some blocks and roll the parameters with the mouse wheel until all fit. There is no need to know what order or name the filters have, if any. Usually the acoustic slopes will land to something like LR4 or some else named filter, when things look nice in the simulator. Of course some familiar filters is good way to start the process and develop from there. There is no reason to stick at some particular frequencies for example, if the response looks better on some other.
Of course the filters have to be then set to the DSP and sound verified by measurement and listening. Rinse and repeat. Have fun!🙂
By simulator I mean VituixCAD since haven't used any other. Very powerful if you take good measurements, not very useful without proper measurements for xo work like any other software. Studying various phenomena in ideal case is possible without measurements, with the diffraction tool generated ideal and simplified responses.
As tip, try to get your head around from making a crossover to making a whole system. The crossover is just a preconditioning to the input signal in electric domain to get the whole system response combine back in acoustic domain, in the listening position. Individual drivers might get "poop" signal because of all the filters but if it all magically combines with the electro-mechanical driver properties, and speaker construct, the other drivers output, and room acoustics back close to original at listening spot you've got your system good. If you instead focus the attention to perfect output at crossover then imagine the drivers, other parts of the speaker and room adds their thing and the response is not what intended at listening spot. 😉 This small mental shift will help to make good crossover. In the simulator one looks the combined output and what ever filters make it, its good.

Who is doing that? As others have mentioned, there's no calculation that can give that information. But you may be overthinking this, start experimenting, run some sweeps one speaker at time, pull the speaker-plugs out of the amp as needed [I've been turning the power-amp backwards to access the outputs faster] Once you get started, you can make adjustments very quickly, check phase using the invert feature.
Stop every now and then and listen to music, number one rule is you need to like the sound!
This response is separated 100hz [24db LR] in each direction:
