I've only built a sub but sure learned lots from the experience. My next project is my fronts and I'm only looking to spend around 1600. If you take the approach that the saving from dyi going into the parts, I'm sure you can build as good a speaker as commerical. Very good drivers can be purchased from manufactures ( I heard vr 4's. Geez they don't make their own drivers). Crossovers? Parts are made by other people. Enclosure? Material again made by other parties. I am leaning towards building the BESL 2.4 using Seas Excel drivers. Not cheap but will be a very nice speaker. Again I'm looking to spend less than 2 grand. The story may change if your spending megabuck, but I my price range you can do just as well as a commerical company.
