Hello,
As I build my own speakers with plans from some quite highly regarded people on the web, yes I have bought without hearing them.
If you have enough reviews from others who seem to have good knowledge of the issues enough to design them, to do extensive testing and using good quality components, it isn't much of a risk. Also, lots of good reviews from others who have built them helps make sure they are at least decent. And yes, need to keep in mind that the quality of the crossover network is very important to the final result. So far they have turned out quite good enough that if I didn't like something about them, I could have sold them for what I paid for them.
FWIW,
Greg
