What happens if the speaker load and crossover impedance design don't match?

The crossover frequency will be different.

I really STRONGLY suggest you do some reading on speaker design to get a better grasp of the fundamentals. The internet is full of information on this topic, in fact, all of the questions you have been asking are easy to answer with an internet search and some on line reading. If you want to get into the details more, you can pick up a copy of the following, which is geared towards the amateur builder.

I have a copy of the 5th edition of the Cookbook that I will be happy to give you since I am in the process of getting rid of stuff. I will bring it to the next meet that is held somewhere in Maryland. Warrenton is a bit far for me.

There is a series of videos about crossover design for DIY speakers. Here is the first video in the crossover series on New Record Day's Tech Talk on YouTube:

Is there something that specifically talks about different loads on crossovers and frequency changes?

Or, a crossover simulator?

In all the network filter equations, the driver nominal impedance is part of the calculation on the design frequency. This is fundamental.

A simple web search on crossover simulators came up with loads of info on design software and online calculators.

For simple, basic 1st & 2nd order crossovers you can check out this site (no endorsement).

Be Resourceful. All the information you need is at your finger tips. The fact you are on this board demonstrates you have the tool to find this information. No reason to keep asking us questions when the information is available.
