A fun thread indeed. Building and audiophile grade setup in my mind would require significant effort and lots of materials. Good drivers are relatively cheap and you can even source inexpensive amps that will be adequate. Still I want you to get an idea of what an audiophile enclosure entails.

3 to 4 drivers per side.
Dual layer construction with a constraint layer in between the layers.

Bracing ever 3 to 4" one every axis throughout the enclosure. Use of 4" rock wool on all sides of the enclosure.

Doing this requires very large speakers even for 2-way bookshelf. Now you can compromise on some aspects. using only 2" on the sides for example. But the best enclosures have this sort of construction above.

I'd suggest the tweeter-midrange enclosure be a separate module too. Makes life easier on the construction. For the bottom I suggest the JL Audio 8w7 be used in a narrow ported box. That will get you plenty of extension. For the top you can get nice results out of the Dayton RS drivers or an existing design

DIY should be something you do for the fun of it not just to save money. If this isn't something you want to build. Buy commercial speakers.

There is a reason we pay to eat out. It's cheaper to cook, but if you don't feel like it and have the cash. Why not give someone else a job that needs the cash?

For commercial options

I suggest Ascend Acoustics or Behringer 2030p's

Or B&W 700/800 series if you can afford it.
