User needs help. Can you help?
Can you explain the height, width, and length of the port?
Can you please explain the height, width, and length of the port? I have changed the height of the port to different numbers but the 3d rendering does not show any changes. I don't understand. When I go to view the parts, none of the dimension change. What part of the port does height and width signify?
Description
I'll make a new box for my 2 Tesla ARN 5604 drivers (approx. 40 years old drivers). At my previous box I figured out that in the same exact box 1 DD612 will have almost identical sounding, just more SPL + higher vent air velocity. At this new 20ish Hz box the same is true for SPL and vent air velocity, but there is difference in sounding too: more steeper transfer function, but the same shape - so still similar. RMS power handling is the same at both. Even this box is better for the DD like for the ARNs.
