View Full Version : Box Designs needed!

Looking for someone to help design an angled box to house three JBL GTO804's being ported around 34Hz. I have a design in mind but I have no idea how to make the port. Willing to mail couple bucks like 5 or something around there...

so you already have the dimensions for the box calculated and port length and diameter, but you just don't know how to fit the ports? or you need everything?

No like I have needed volume but figuring out best way to fit port...I tihnk I might have it though but yeah..

1.6-1.65 volume needed port 30 sq in 10x3 38.** long...but I am redesigning the box right now so yeah...

ok so came up with

10x3 36.06" long...tuning 34Hz

But I entered 1.662 as enclosure volume so how much displacement is that port gonna cause? I need the volume to be ATLEAST 1.662 or so WITH the port in

how thick is the wood board youre going to use for the port?
are you making the port with 4 individual sides, or are you using the box wall as part of the port?

and here is an idea on how to run the port.

Was using part of the box as port wall..I was just gonna bend it til I got the 38" long...nice box you got up there....what program did you make that with?

did you figured out the displacement of the port wall?
if not let me know how many wall you are actualy making and the size of those boards and ill calculate the displacement.

thanks for the compliment on the drawing.
