Any ideas or recommendations?


Rethink your application. There's a number of reasons why virtually
every speaker system with pretentions to quality is at least 2-way.

Don't you like the frequency response of the one I have chosen ?

Two pretty serious problems:

(1) Xmax of 0.3 mm, when it should be 3-6 mm if an 8" driver would have
serious bass.

(2) Note that the off-axis treble response falls off above 1500 Hz.

I know that I will have to help him with a tweeter over 10 KHz but
this will be done with nearly no electronic, just *a* cap !

Basically, this looks to me like a cheap driver with fairly nicely
controlled cone breakup. The cheap part comes in because they obviously made
the magnetic gap very short to goose the magnetic field density up, in order
to get relatively high efficiency.

Manufacturing DIY full-range speakers could be an interesting job of
luthier.:-)

Those nasty laws of physics run against this project.
