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.

I know enough about speakers to realize that one speaker can't
do what two or more can. I'm actually the other extreme - I think
that the best sound comes from a series of 3-5 speakers all
operating in their optimal ranges.(ugly crossover, though)

NoRH tried it with minimal success. Magnepan is trying it with
their MMG-W(one single panel) - of these attempts, the Magnepan
is the best, IMO, but it has a 100hz - 15Khz range. That's
as good as one speaker will get you with today's technology.

But a two-way speaker crossover is almost idiot-proof as you
really are only matching two speakers together, and most
have a good deal of overlap - it's not hard to get flat
response in the midrange these days. Plug in the crossover
from the kit, tweak it if you want with a few better components,
and enjoy. Now, three or four-way crossovers are a whole
other story. That's the kind of difficulty you're imagining.

The same Magnepan speaker, for instance, with two panels and
a bit larger size(few inches) is their MMG. 50hz-20Khz.
Not much larger, but a full octave better bass and cleaner
top-end.
