Regarding the Neats, I have no idea. But there are also speakers like the Dutch-n-Dutch which are powered. And if a powered speaker was chosen then they do not even require a speaker cable.
Whether an amplifier with room correction is used or not also adds some decisions… and these days there is a lot of options that can be used to fix up a room digitally. But the purist approach is often preferred.
There are so many options, that it should be expected to be a complex process to come up with what is optimal. Which can make it a bit of fun… or daunting.
Again, starting with the speakers are working backwards is a sensible way to approach it. Or if one wants the room correction, then know what a particular amplifier can drive, can also influence the speaker choice… so it can be complex.
