The Frech Gallo bigger speakers are always praised in TAS and Stereophile, ence the hi price.
I just would point out the sphere is the best enclousure shape, the second best is the cylinder/barrel or bazzoca, unfortunately this little speaker SPL is too low(87dB) what avoid tube amps, also the cone is not paper, and will no give that organic sound.
Looks a great speaker for TV or computer, if it had no filters(capacitor/resistence) inside the enclousure.
