Is it true, that it's not good the tune a box lower than the subs Fs? I always thought that you can tune a box lower than the Sub Fs, what's true about this and what happen if you tune it lower than a subs Fs? anyways, thanks.

No.

Fs is simply free air resonance.

The lower the F3... to a point.

OK thanks guys, so you can put a subs that have a fs of 40-45 Hz in a box tuned to like 32-34hz? will it still be able to to play those low freq without a problem?

Not so sure why you'd tune low at the same time while buying a sub that is made for output and not response.
