Really nice work!! The only thing that I have doubts is the position of those yamaha monitors. I mean, I get the concept of flush mounting the loudspeakers to obtain the acoustics benefits of it, but those monitors have a ported vent at the back (HS8, HS5 model?) so putting those right there, can modify in a non-beneficial way the frequency response of the monitors because you're not giving enough air space behind for the ported vent to function as it should be. Or maybe the enclosure where they are have something to avoid that problem?
if you set up the venting correctly, the rear port and active monitors will work ok. the challenge is to provide enough absorption on the ported models in the soffit. also, you need to adjust the baffle step compensation a bit differently to account for the new LF response of the speaker which will be different than a front ported or sealed box. i generally don't recommend sealing the rear port as the speakers are typically not designed for (x-overs, spring, etc) it and so best to leave them open.

Yes, the thing is, that I haven't got any other option, only those HS7. And Yamaha's are really familiar to me, so as a first experience I did mount them. I tried to not overload the rear port, enclosure box is much deeper then the monitors and I tried to make it as much ventilated as I could. I have a plan to try to set up another monitors, but I've still struggling for which ones to go with the front-port.. Maybe you could give me an advice? Really appreciate your comment!

Considering the investment you did for the design and acoustic treatment of your room, it is worth upgrading your monitor system too. The HS7 are great, midrange detail is clear with those. Now, the ones I would recommend that have front port are the Focals Alpha Evo 65. A pair of those are aprox. double the price of a HS7 pair, but as I said, it's worth the upgrade.
Sealed LF drivers ROCK! But so do all the Neumann Speakers, even the little ones.
