Hello all
I have a box under construction which has a front slot that bends 90 degrees inside. Below is the pic. Currently, the baffle is 16mm. I need to increase this to another 40mm to total 56mm. Do I just shorten the port wall 40mm from the back?
I want to leave the driver at 16mm and have it recessed by 40mm so that I can have a flush grill and leave plenty of space for its crazy excursion

If all four sides of the port are extended by 40mm, and the interior volume of the cabinet remains the same, then the slot port wall behind the driver would need to be shortened by 40mm to maintain the same Fb. That said, reducing the port length by 40mm slightly increases the cabinet interior volume 😉

Thank you for that. Crazy coincidence on the 40mm. 🙂 Felt silly asking it, but didn't want to make any assumptions. I didn't think of the increase to the cab volume, about 200ml. Is this a slight change or a lot for a 18L net cab?
200 milliliters is 0.2 liters, 1.1% of 18L, a very slight change.
Rounding the corners on the ports to reduce turbulence noise would be more than a slight change.

Thanks man, that's very helpful and inspires to continue with some confidence. I am thinking of 5-10mm radius for the port exit on the baffle to merge with the rest of the contours that will be applied
