Speaker Box Designer is the app for designing the boxes for your loudspeaker drivers. The app will size the box (calculate the box volume to match your driver), calculate the port length (if you want one) and will also plot the frequency response of the finished design.
You can design Closed (Sealed), Ported or 4th Order Bandpass enclosure designs. The sealed design is the simplest to construct, the ported design gives an improved bass response and the 4th Order Bandpass design is great for sub-woofers.
To use the app, enter the details about your driver and the type of box you would like to use. The details about the driver (the Thiele-Small Parameters) can be obtained from the driver’s data sheet, the supplier’s catalogue or from the internet. If you select a Ported or 4th Order Bandpass design, you can also set the port diameter. The app will then calculate the box size for you and you can plot its frequency response.
The app works with both metric and imperial (English) units.
I have been asked by a number of people why the app doesn't calculate the box dimensions from the calculated volume. The reason is that there isn't just one possible solution - in theory you could have any shape box you like. However, to be helpful, I do recommend that your box has the 'Golden Mean Rectangle' proportions of 0.618:1:1.618 as these are considered by many to be the optimum shape for the acoustics (a cube is certainly the worst shape acoustically). You can calculate the INTERNAL box dimensions with the following formulae:
First find the cube root of the desired box volume, we will call this r3V
For Box Volume in cubic inches:
L = r3v * 1.618 (answer is in inches)
W = r3v * 1.0 (answer is in inches)
H = r3v * 0.618 (answer is in inches)
For Box Volume in l:
L = r3v * 0.1618 (answer is in m)
W = r3v * 0.1 (answer is in m)
H = r3v * 0.0618 (answer is in m)
________________________________
If you have a small screen, you may need to scroll down the page to see the calculation results. This program performs a number of calculations including Box Volume, Box Resonant Frequency, Minimum Port diameter and Port Length - these can be seen in the fourth screen shot. Be sure to enter your data correctly, as if you make mistakes, you might incorrectly think that part of the app (such as the ported calculation) is not working correctly.
If you have any problems it is much more productive to email me before leaving a negative comment, as then I can do someting to fix the problem.
