Joe X Posted March 19, 2012 Report Share Posted March 19, 2012 (edited) With aeros this can work: Fb = 35.133 Hz Vb = 3.627 ft^3 Number of Ports = 3 Pipe Port Diameter = 4 Pipe Port Length = 19 3/4 External Length = 5 3/4 This would make a nice daily setup only, the net volume is larger than you would usually find ina SPL box for those subs, your vehicle is large also so cabin gain would be limited. what tune is this? with the box only being 20 it woont fit without an elbow, any idea how to get all 3 in there? what is the external lenghth for? Look at the Fb parameter it's about 35 Hz and check the external length specification, that means 5 3/4" of the port would be external.

Well flanged aeros can sound cleaner than slot ports due to reduced turbulence, also you can change the box tuning easily with them which you may need to compete.

Joe X Posted March 20, 2012 Report Share Posted March 20, 2012 ok , i see how this is done, but is there internal tube in the above picture? having the internal and external is throwing me off There are fully internal, external and mixed.....or you can go with a slot port if you don't like aeros Quote Link to comment Share on other sites More sharing options...
Joe X Posted March 20, 2012 Report Share Posted March 20, 2012 Yes you can do a fully internal slot port. Quote Link to comment Share on other sites More sharing options...
