In a vented box tuned to a particular frequency the port becomes deeper as the area increases.
Intuitively I would expect that they would increase in proportion.
Double the area should require double the (end factor corrected) depth.
Is this correct?
I have box tune charts but not a formula.
The charts show the actual depth is not proportional to area but I can't tell what the corrected depth is to see if _that_ is proportional.
Any one here actually understand this ?
I don't want to just be a chart and/or CAD monkey.
But mainly I plan an enormous port and it's off the chart!
TIA
