Francis summed it all very well...

Yes ok , but anyway you must consider it so it’s better if you have a target. If you don’t have a particular target o recipe haw you decide which type and how much absorbing material you put in a room? This affect your RT60? right?

Of course I will check it all out and measure, but it never is a surprise.
What I mean is that once I got the geometry / RFZ / Broadband + LF management, the room is already within the RT 'target'. It's low and well within the .4/.2 benchmark. If it's not then I missed something. Controlled LF implies low RT. Then Diffusion will balance the room properly and even out what (and if it) needs to be.
All designers have *RT* in mind when working - but it's not a variable on it's own, it's one variable that is dependent on other. And Ethan makes a good point in his post about RT.

Sorry if I insist but my question was simple : RT 60 more close to a control room or to a living room? And if it’s more close to a control room or a living room we should quantify this value otherwise it’s just an useless discussion

The trend here is obviously close to a CR. Now to quantify this value with a strict number like .3/.15 would IMHO be strange. It will vary with every project. And it's also a question of taste - which cannot be quantified. The broad benchmark of .4/.2 is a good reference point, but that's it. If the client wants a RT higher than .2 in the higher freq range I will do just that. But also warn him...
