Is this true about Slot port boxes?

ok so minus 1 7/8 from the total port length

It *adds* effective port length if it shares a wall with the enclosure.

When calculating how long to cut that inner piece, yes. Again, check your modeling software. I suspect 2" off either way is not going to be audible.

ok so,Is it true that you should minus the width of port(3.75" inches in my case) from the total length of the port length? I was told the back wall can act as a port extension or something.

I was just curious if this is true or not?

If it is a slot port, take away half of the port width from the port length.
