>>From the absence of large compression ratio a larger dispacement of the diaphragm results and then a quite high level of distortion (compared to a driver like the JBL245x by example) and a bell shaped frequency response curve.

So that seems to be negative...

If you use a bit of equalization between 500Hz and 3000Hz then the efficiency fall to 105 or less.

>>IMHO the rear cavity is also too small.

i dont understand, the rear cavity of what ?

>>The very low compression ratio sounds less 'squeezed' than the typical 10:1 ratio unit.

and this would be a positive effect.

so the question is: does not use a phase plug in this frequency range, in the end, bring better, ore worse results ? also, as it is used this way, probably would it not beam ?

Avantgarde uses a different impedance coil so it requires no attenuation in the network.

dont understand this.
