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
In this project I have simulated all 4 boxes for this woofer what can be done using SBL. I used stock parameters from the SBL's database + I filled in the missing parameters. My personal needs: ideal power handling at the woofer's peak power at 20 Hz and higher frequencies, acceptable group delay and acceptable vent air velocity between 20 and 80 Hz. For Vbs and Fbs see the Graphs History. Port areas: vented - 36x314 mm, 4th order - 76x314 mm, 6th order / low-chamber - 54x314 mm / high-chamber - 71x314 mm.
