"I assume the craftsmanship of the enclosure is probably the most important part of this, right?"
Not really, the drivers, the crossover and the enclosure are all equally important as they work as a unit. The drivers can be replaced or serviced as can the crossovers if needed. Don't worry about that, just buy the da*n speakers and be done with it. Then we can move on to what you will power them with. You have to start somewhere, we all did.
