I know of only a few full-range designs that work very well. Basically
you have a 15Khz top-end and maybe 80hz, but that's not "flat".
Building one yourself - that's just asking for a dissapointment.

Eh, Joe what happened to you ? Why are you so negative ?
Full range speakers are easier to built than 2, 3 ways speakers since
you don't have to tweak a crossover. Moreover a bunch of different
optimised designs are available on the internet.
