Default CGS-->MKS

There are 2 systems of measurement using metric units.
The MKS sustem (Meter, kilogram, Second) and the CGS (centimeter, gram, Second).
The CGS system is slowly loosing it's following as most scientists convert to the MKS system.
However, it seems that among the electrical engineering crowd the CGS system is still quite popular.
Audio Engineering is a subset of Electrical engineering and there is still quite a bit of favor for at least the use of centimeters, if not the entire CGS system.
Hornresponse uses cm units as do most other simulation programs.

I have downloaded stepped-TH.xls sheet for folding a box, but I think it is not adequaat because it has not a constant tapered line, there is a straight piece of line, then again with some more cm2.

folding a box is I think best to cut it in parts and make the folding.

The xls sheet has just one kind of box? if I do fill in a slim box 3 times folded it prints just a part of the box on screen.

I use cm units here so it is easy.

thanks

I did make some errors, so I have to drawn again, the box will not be much different of size.

I did see also just in hornresp that it can a lot better also, with smaller coil.

keep follow.

i downloaded the .zip file into sketchup and found no dimensions, that's why i asked about the dimensions.

smaller coil? do you mean an inductor in the circuit? in series with the woofer?
