The larger box would need a larger diameter port to maintain the same Helmholtz frequency. It could also use a shorter port, but that's not possible since port size equals baffle thickness in this case. The point is that while this isn't very specific, in general, Rodney has gone in the right direction. If interested, box frequency can be measured using information contained in the post called, "Measure impedance."
