Hi guys I'm new to the forum and this is my first post. I just started out building my own boxes for the past 2 years now and need some assistance on this new build. Attached is the pictures of the box in progress. Can anyone assist me with port tuning (I'm from south africa so in cm would be great). The dimensions are : Height 41.5cm Length 90.5cm Width 45.5cm Sub mounting height 17cm All wood is 20mm plywood What is my current port tuned at 52.5cm port running in an L shape in the box 5.4cm width Length 41.5cm pictures attached The sub mounting height is basically the walls around it. Thanks for the time
