Brilliant post Ivan!

I see people at the top end of the game that don't really understand this.  Once inside, anything below 100hz becomes a lottery dependent on the room.

I suggest avoiding a fixed number for that transition.

Schroeder's equation provides a better estimate of where the "lottery" starts.

Critical frequency = 2000*SQRT(RT60/V) (metric)

7.000 m3 with an RT60 of 1.6 seconds lowers the critical frequency down to 30 Hz.

The range below that is governed by room modes.

Mind you these are estimates that indicate the range of transition. Not exact figures. They put you in the ballpark so to speak.

As with all other things, it is not an exact point-but rather a large "grey area".

Just like loudspeaker coverage-it does not stop at the specified angles, but rather starts before the angle and then continues a bit after that-and is different at different freq.

Or thinking that a crossover does not allow freq above or below to come out.
