ive maybe a dumb question: how a speaker can delivery more spl close to his fs than in other point that is not so close on fs? i misunderstand some basic concepts? ---> fs=28hz spl by graph 30hz=84db spl by grap 40hz=80db |

Fs is the speaker free air resonance. A speaker is a mass and spring system with a frequency where it naturally vibrates the most (resonance). When it's at resonance it displaces the most and generates the most SPL.

... Subject to Q-factors. A low-Q driver won't show any more excursion at resonance unless driven by some series resistance. Lots of reading to be done! I'd suggest learning about Thiele-Small parameters. Chris
