labyrinth style port tuning

[CJ18]

Can any one tell me how to figure the tuning on a box with a port like this?

http://forum.realmofexcursion.com/enclosures/51745-bass-reflex-flared-labyrinth-port.html

Ive got a box built like this but with only one turn of the port and have no idea what the tuning actually is. The box is for 1 12 with 3.4 cuft not including the port and hits every note great but i would like to know what the actual tuning is. Any help is appreciated.

anyone?

looks like a very elaborate slot tuned with a ton of KERF done to keep the air moving smoothly through that many bends

Why not just ask thumper, hes got a box build thread on here.

It looks like it would do a decent job, the less bends the better though, less likely to get port noise.

Honestly, it just looks like a really long, low tuned port bent to fit into a smaller space.

You can try, but I'd be wary of the air beeing caught up in that many bends.

In not using this design i was just using the pic as an example. The port i am using only turns once. But my question remains the same how do i figure the tuning of the box with this type port. My box 3.4 cu before sub displacement not including the port . The port is 2" wide 18" tall and 37" long.

3.4 cubes is not a lot of airspace for 2 Solo-X 18's... or is your sig just a wish-list

he said it was for a 12 not his 18's
