As a learning tool, I want to start speaker testing using my Anthem MRX-540 (with ARC Genesis on my laptop) with it's microphone instead of spending the $ right now on a dedicated PC, sound card and other test gear. This will be the next step once I've installed the new XO and components for the tweeter in a pair of Infinity RS2000s. My idea is to safely test the tweeter to get an FR curve and use my DATS 3 to get impedance curve. I'm hoping to export the Anthem tweeter FR data from my Windows 11 laptop into simulation s/w together with the Impedance data. I can then import the FRD & ZMA data for the selected replacement woofer to simulate the rest of the XO components and adjust the tweeter level.
I'd appreciate feedback about this approach. Thanks!

So, the Anthem is an A/V receiver with DSP and Genesis is room compensation software?
It sounds as though you have RS2000 boxes with nothing in them?
What is it you're replacing and what will be original, ie what is the mission? New crossover old drivers? New drivers, new crossover?
Will you redesign the crossover or are you looking to copy the previous responses?

Yes, Anthem MRX540 is an A/V receiver and connects with their Genesis room compensation. However, Genesis also allows me to generate FR curve before any correction is applied. My thought is to use the A/V receiver paired with Genesis on my laptop (normal setup) for near-field tweeter measurement and later woofer near-field measurement.
The RS2000s have good tweeters but toasted woofers. My mission is 1.) learn 2.) end up with some good 2-ways for my office/cave. I found a set of videos of a Brit who kept the cabinets and tweeters but replaced the woofers and crossover. He showed near-field testing results + combined results as flat within +/- 2.5 db and the XO values that got him there. I plan to copy the tweeter XO components but test/simulate for the woofer XO comps.
The woofers he used are no longer available but I selected Dayton RS180-4 (7") which (from Loudspeaker Design Cookbook) give me an f3 of 61hz. (original Infinity spec was -3db @ 57hz)

He actually showed the microphone on axis for both the tweeter and the woofer and probably 2 inches away
