Crossover Feedback please!

Hi Dave, I really appreciate your input here. I have been learning a lot, but still have a ways to go. As far as the 101.5db FR curve, I had forgotten I had raised the voltage on the amp in the program a while ago and paid little to no attention to the height of the spl and was only paying attention to the "flattness" of the curve. After lowering the amp to the standard 2.83v you are correct and it levels off close to 95db for the woofers.

I'd missed the 6V source in VituixCAD (old eyes 🙂. Yes its good to at least normalise / use 2.83v sensitivity for crossover design.

We also haven't seen your system impedance.

What DSP do you have? as it seems you are going for a 2 way MTM, unless you don't have enough amplifier channels or your DSP lacks volume control or sufficient gain (2VRMS usually fine from unbalanced RCA for most amps to reach max output) for this very simple crossover, your DSP should be able to do it all. that way you have less impedance concerns, and can tweak away.

Since you going to use DSP for final response pollishing, I suggest you to use DSP for BSC as well.

Thank you for your insights! I do plan to use some built in DSP likely with the Anthem MRX740 AVR and then an external power amp. So, from your perspective, you think I could likely "polish" things off within 4-6db using DSP and likely still be able to achieve a good sound? I just keep going back and forth if I am over think this crossover design and should just order the parts and start building, or I should take it much slower and do all the baffle measurements etc. first.

I intend to use the Anthem MRX 740 and likely use the BASxA3 as an external amp. From what I understand, the Anthem has pretty superb DSP. I just want to make sure I have a good foundation before I start spending too much money on these speakers haha.
