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
This project I created using WEB designer, and I simulated in it a closed, a vented, and a 6th order bandpass box. My rules and needs: using stock parameters from SBL speaker database, at 20 Hz and higher frequencies: reach but no overpass Xmax, ideal power handling, acceptable vent air velocity and group delay, and the largest outer dimension less than 1000 mm. The loudest at low frequencies is the 6th order bandpass box, but on 3D and on drawings is the vented.
