Box Frequency Tuning Calculator - FAQ/Tip Guide

1 - First and foremost, the RE calculator is *not* spot on, and is limited in design, so no, it will not match this calculator.

2 - When doing an oddly shaped box such as a fiberglass box, or you know the volume of a certain box you have in mind

that you want to build, put the net volume in the 'Desired Net Volume' box. This will bypass all dimensions entered

preventing you from having to guess dimensions to get a certain net volume and will allow you to tinker with different

port sizes and tuning. So if you know you want a box with 4 cubic feet of net volume, enter '4' into that box and it

will allow you to adjust tuning accordingly to that specific volume. Keep in mind that any displacement nor port volume

is NOT subtracted from this total.

3 - The 'Desired Gross Volume' box acts much like the Desired Net Volume box, except all displacements are taken into

effect.

4 - If the number of aero ports is greater than 0, then that automatically gets taken into effect and the calculator ignores

the dimensions for slot ports.

5 - The '# of Common Port Walls' box refers to how many sides of the box are going to act as sides of the port.

6 - Port length uses the box wall or baffle(s) as part of the port length. So a port that is 10" long with one baffle using .75"

wood will only need to be 9.25" long as the box wall or baffle(s) will account for the other .75". If using two baffles,

then it would be 8.5" long as the baffle will account for 1.5" of port length.

7 - Port walls are defaulted with a .75" thickness.

8 - Regular square/rectangle boxes do not need any numbers entered into the 'Height 2' or 'Depth 2' boxes.

9 - Pressing 'Enter' will prompt the program to print.

10 - Slot port area range is based on 12-16 square inches of port per cubic foot, while aero ports are based on 9-13 square

inches per cubic foot.

10 - On the cut sheets of boxes with different depths and heights, you'll notice 'H1' or 'D2' next to the measurements.

These represent which dimension is which. Here are two pictures to illustrate:

Box with one height, but two different depths: http://img59.imageshack.us/img59/8449/angledcutsheet1.png

Box with two heights and two different depths: http://img163.imageshack.us/img163/607/angledcutsheet2.png

If they do not go in the proper order, the sheet will not come out properly.

--The following are links that illustrate how each ported box is taken into effect in the calculator (sub and port position can be upwards with the same effect):

1 - Port with 0 common walls: independentport.jpg

2 - Slot port with 1 common wall: bottomportbox.jpg

3 - Slot port with 2 common walls: middleportbox.jpg

4 - Slot port with 3 common walls: slotportbox.jpg

I think I would want someone to hold my hand and design one for me because I know it's right and not wrong. You feel me?
