help buiding a helmholtz resonator

[Telemaster]

I have found speadsheet calculators for buiding these resonators. But, none of them include the overall length and width of the box. Does anyone know why???

Thanks,

What counts in the formula is the depth of the box behind the slats.

You can dimension the length and width to fit your needs.
