if a cab is built solid to typical specs, say 25.5"H X 23.5"W X 18.25"D for a 1x15 cab. how much difference does the speaker make in the tone of the cab? and if all else is the same (quality of build, wood, covering, and speaker) what tonal differences would there be if any between a cab of the aforementioned specs and one that is 27"H X 25"W X 16.5"D. where the bigger cab has a smaller port and the smaller cab a bigger port? and what kind of difference does the size/placement of the port make? thanks in advance.
