    Some follow-up questions, if you don’t mind 🙂

    1) In your very educational calculations (thanks for that!) you conclude a port length of 3.73 inches. Is there any calculation / requirement for the distance from the “internal end” of the port tube to the front panel? See sketch

    2) In the assembly manual for the C-note kit the recommended port length is 7″. I imagine that’s the reason the speakers have a relative long depth of 9.5″?  Is it so that the longer port length you have, the more bottom you will get? Your calculation states a port length of 4.06″, which would allow me to make a more streamlined box, but what are the trade-offs?


    Overall, I guess what I am trying to ask is, if the depth of the box has any importance (other than the required length of the port, of course) or if it is just the overall volume H x L x D that matters?

    Thanks again 🙂
