25 years ago I went to high school in Canada and one of the things I remember about the metric system or SI is that 1 mm cubed is 1 mL. So I used that to confirm your conversion. It still doesn't seem reasonable but that is mind just not being able to get around it yet. Thank you for bearing with me.

I briefly checked out your sub build thread. Wow, all the way from Cairo! I am amazed by that. How do your neighbors like you now with those subs?

I have some reading to do and I have some time but one thing I do know to ask is about the port. What size and what length including the flares/flanges?

Thanks again,
Alex
