Box Tuning Help

[FellCrustacean8]

I need help making a sealed enclosure for a new build. Can somebody leave some formulas that also tell what unit of measure is to be plugged into it. That's the main issue. Websites gave formula but not the units to use. Your help is greatly appreciated!

Read this post:

The design formulas are baked into the software, and the units are easily changed by clicking on the unit designation next to the data field with the mouse pointer, before or after entering data. Any already entered data is automagically converted to the new unit.

So enter your driver data into the fields, each is labelled with the unit type. If your data is in a different unit, click on the unit label to cycle through the available units for that spec until your unit comes up, then enter the data.

Once your driver data is loaded, you start a new project with the wizard allows you to choose the box type (sealed) which engages the formulas automatically. Then you can adjust the variables for the box, and change units in the same way as the driver data. It's easy to use and free. Hope this helps!

Edit: Another resource, formulas with units. Remember Q (Qts, Qtc, Qms, Qes) has no unit. It means Quality.
