Hello
I finally updated the speakers, a new design, and a port in the front, I can now put the speakers closer to the wall, the low frequencies are more controlled, thanks for the help. 
Fusion fully passive version.

Hello,
I finished the speakers, it plays really well, except for the bass controls, I can't find the right amplifier yet, I've tried these Primare, Naim supernait 2, Hegel Rost, all of them playing very good mid and high, low frequencies are not good enough and amplifiers are not cheap.
I'm thinking maybe try fusion hypex ? Is it worth it ? Maybe then try to find a tube amplifier  with them for mids et high.
Thanks for your help.
