Volume size box help.

[pulsardet]

I have a project in fact this is exact replica of the cynosure part express speaker, a center line array.

My real question is the original box has a size of 24x4x14 that give .519 ft volulme,

In the project they say the best would be to put the port up front, instead on the side on the original plan, So I calculate if i put the port on the front that would give me a 34x4x10 and a .516 ft volume. compare to .519 ft volume

Is their any problem with my new size box ? Or it's only the amout of volume that is important, in this ? Sorry If it's sound has maybe a newbie question.

Thank you for your help.

I would try and jig the measurements to reach the original volume, although it is only a very small reduction so you will probably get away with it.

Hmmm.... that's 5.18 cu in. My poor woodworking skills don't allow me to worry about such a small difference.

From years of cut and try experience, I can tell you this: if you want to change the behavior of the box audibly, you'll have to make a bigger change than .5%.


Thing is, 34x4x10 is looking a lot like a TL. Maybe someone with MathCAD could run some numbers and tell you if you've transitioned from a box to a pipe.
