Posted May 7, 201312 yr I'm in the process of designing an enclosure for my Fi BTL UFO 12. I've drawn up two different designs with the only difference being the way the port is constructed. I've seen it done both ways, but I am unsure which would be most beneficial in my situation. Each design is 2.85ft^3 net tuned to 33hz for a front firing setup sealed from the trunk of a 99 Pontiac Grand Am. Does anyone have any experience/input on which would work best for me as far as loading, port noise etc.?Please use "left design" and "right design" when referencing for clarity as I am unsure what to call each one specifically. Note: I will not be adding any 45's within the port, but each edge will be rounded over with a router. I will add 45's within the chamber where necessary though.
May 8, 201312 yr Left design would be my choice.The only reason I say that is the right design has the port opening potentially too close to the driver which could cause unloading.Other than that the way you build the port isn't that important if everything specs the same.
