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.
This app is also suited for Tablets, graphs are shown in fullscreen.
Just enter your Thiele and Small parameters for your driver and you can choose different types of speakers: Sealed, Vented, Sealed Compound, Vented Compound, Push-Pull, 4th Bandpass and 6th Bandpass. It can calculate optimums for a sealed enclosure, vented, sealed comp., ventend comp. and 4h band pass. If you choose a vented or band pass enclosure, you also can calculate the vent length and minimum port diameter.
Speaker Designer can handle a number of metric types: Inches, cu. Inch, cu. ft, ltrs, cm, mm, etc.
Speaker Designer doesn't give you any dimensions for an enclosure. It gives you the volume for an enclosure in a given configuration. You will have to determine the dimensions your self. Don't forget, the volume is the net volume.

"I saw/heard a major difference . It realy helps."
"Omg. Cant believe it worked"
"Even if it doesnt work, its good for annoying people. Seemed like it worked though"
While the old fashioned method is still the best, Speaker Clean utilizes patent pending technology and ultra sound frequencies to attempt to dislodge dirt and particles that may be clogged in your speakers. Simply lay the device on a flat surface then tap the whirlwind button to initiate cleaning. The complete cycle takes less than thirty seconds but may provide a world of difference for speaker clarity.

It uses the proximity sensor to know if the phone is near your ear or not.
If you are using any type of headset, it will turn the speaker off, regardless of the proximity sensor and use the headset.
Whenever you are in a call, a new "control" button appears (default location is on the top left of the screen).
Pressing this button enables (Green icon) or disables (Red icon) the service for the current call.
Alternatively you can use notification on the status bar instead of the control button.
Please note that when disabling the service it will turn off the speaker.
Furthermore, the speaker button of the dialer may not indicate the current status of the speaker (on\off), nevertheless the status is changed.
Some devices may need to be calibrated for the app to work correctly.
See 'Calibration' option in settings if needed.
- Set default service status.
- Disable the service when phone is set to silent or vibrate (optional).
- On each call, you can change the service status for that specific call (It does not change your dialer).
Using it will turn the speaker on if service is enabled, and off if service is disabled.
- Set the speaker status when call starts.
- When changing to speaker, set the volume to maximum (configurable).
- Keep the screen on when speaker and/or headset is in used (optional).
- Control for speaker on\off delay (separate delay for on and off).
- Select between using control button or notification on status bar.
- Custom location of the control button.
- Custom transparency of control button.
Default setting is to turn off the speaker quickly when putting it near the ear, but a longer delay to turn it off.
This way if you just move the phone for a second from the ear it will not turn it on.

More from developer
Your phone will blink in the rythms of music with the camera's LED flash light (can be disabled in settings) and with funky colors on the screen.
App is very lightweight and easy to use. In music mode you can easily adjust sensitivity and frequency and your phone will perform well as a light show at various volumes and music genres.
In strobe mode you can easily adjust blink duration and frequency and turn your phone into the strobe light.
In manual mode you can use your phone as a torch light (on/off) or manually insert some crazy light effects.
Speed is displayed with needle gauge and with digital numbers. App also displays top speed, average speed, traveled distance and current slope. Stopwatch is also included.
Speed units (metric/imperial) can be changed under settings. Accuracy depends on GPS quality and can be a bit lower during a walk. GPS has to be turned on to show speed.
Feel free to contact me if you have any trouble or if you find any bugs. Remember to drive safely and do not look on the phone while driving!
It is very easy to use and offers a lot of useful features: high RTA refreshing rate and frequency resolution, adjustable sound pressure level scale (up to 150 dB), RTA peak hold function, flat reference line, local peaks...
RTA measurement can be recorded on 3 separate channels. User can later compare SPL and frequency response charts between the channels.
It also includes a signal (tone) generator, which helps us measuring the frequency response of a sound system.
Input/output can be adjusted to Internal, AUX or Bluetooth. However, all I/O options and combinations do not work on all devices.
Microphone can be accurately calibrated for each frequency band separately.
Layout of the accordion is based on Slovenian accordion and available in all transpositions from A D G to C# F# H.
Accordion can be used on phones or tablets. User can pick between full sized and smaller layout to play the accordion easier on smaller devices.
You can choose how much to stress your battery by checking the checkboxes. Then you have to run the test for a couple of minutes. The app updates battery's discharging speed and its remaining time every second.
You can stop the battery test whenever you want and finally look at the battery discharging chart.
App also calculates final voltage on car audio amplifier and recommended fuse size.
App can also consider voltage drop on power sources (battery and alternator).
App can be very useful for everyone who wants to estimate battery and cable size, needed to support powerful car audio amplifier.
Units can be changed under settings (metric or imperial).
Draging and braking tests use automatic start-stop and write the measured speed and distance data on the chart. Accurate approximation algorithms are used on devices with slow GPS update rate.
You can fully customize benchmark parameters of the drag and even use freestyle mode with a racing car style speedometer and stopwatch. Units (Metric/Imperial) and zero speed threshold can be changed under settings.
It can accurately help you tune the pitch of all tones from C1 to H8. You also can play the corrected tone with the same voice anytime you want. If you use guitar, it will play the properly tuned guitar tone...
You do not need to change any settings: just run it, see your tone pitch and play the properly tuned tone.
