Soft flush mounting Genelec subs - gap needed?

Hello! Looking for some advice. I'm placing 7360 subs inside an rockwool absorber wall. The sub's front will be adjacent to the fabric covered surface, with the body of the sub inside the soft absorber material.

My question is, in this case, can I get away without the 7,5cm air gap on the port side, which is described as necessary for air flow in the manual, when flush mounting inside a solid wall. My thinking is there is still decent flow of air into the rockwool anyway.

I would leave even more than 7.5 cm arigap if i'd be in the same situation. 

From https://www.rockwool.com/why-stone-wool/

"Stone wool also effectively reduces airflow and sound transmission, while providing higher airflow resistivity"

and

Consider the thermal properties of rockwool or stone wool, possible heat from the sub will not be dissipated easily since the subs would be surrounded by insulation.

You would get way less airflow as you're probably assuming. Still a good idea the rockwool-wall, but just leave a bit more space
