View Full Version : question on box tuning and RE box builder

07-09-2007, 03:02 AM
No im trying to tune a box for a fully loaded btl 15, lookin at 4.5 cu ft after displacements @ 45-48 hz, mainly for SPL. now im having a problem with the RE Box builder. Im attempting to build a box with these specs:::

Width 33
Height 17.5
Depth 21.5

i want the port width to be 5 inches, yet it wont let me change the port length 1, or how long the port goes in, thus keeping the tuning low. Is there a way that someone could give me a certain amount of port area for this sub to be tuned at 45 hz? Thanks

Do all the cuts as they have listed, but when making the cut for the port make it 13.5" x 16" instead of 15.75" x 16" and that will get you close to the 45-48hz tuning that your looking for.
