DIY speakers as a hobby is mostly about enclosures and crossover networks. It's quite rare that people would build their own speakers drivers (some planar speakers being an exception).
Where it's rewarding is taking available drivers and building a full speaker around them -- usually optimizing for performance vs cost. It's difficult and expensive to build really high quality loudspeakers. Add markup to that and the retail price of a well engineered speaker will quickly go into 5 digits.
The speakers in my living room are DIY (though they don't really look "DIY" as far as that might carry negative connotations) and they're an excellent value. They were also fun to build. In no way was I disappointed afterwards because I had not, say, wound the voice coils myself.
