Joe X Posted December 4, 2012 Report Share Posted December 4, 2012 could you make a cut list for a 5 3/16" port tuned to 33 hz? Do you tihink that it will be loud if i do that? I tried to make the port wider but the port becomes too large. So this is an alternative but I need to tell you how the port parts have to be cut: Also let me know the length of that panel with a question mark -- be aware that the port has to be perfectly in the center for this to work so the left front and the right front panels must be identical in length.

Ok take a lot of care with future measurements, regarding your issue you can repeat the front panels which is best or do this: Just take the center (18 1/2") , cut and place the port parts as shown, the full spec of the parts is as follows: Shared Port Internal Assembly Parts: 2 x Front to Back = 18 x 12 1/2 2 x Extension = 3 3/8 x 12 1/2 In this case the port must be 4 1/2", since your parts don't fully fit I placed some 45s there to reinforce the corners. If you have any other questions let me know. Link to comment Share on other sites More sharing options...
