SpeakerSim speaker simulation software

[LightBit]

New version 2017-11-28:

• New default positions for new projects (speaker and listening position used to be the same)

 

[LightBit]

New version 2017-12-03:

• New power handling simulation:
  • IEC 268-5 power is shown instead of linear power
  • "Pe defined at" parameter added to driver for tweeters (when power is defined with high pass filter)
• Excursion simulated with IEC 268-5 filter

IEC 268-5 filter:

• low pass 3dB filter at 0Hz
• low pass 12dB filter at 5kHz
• high pass 12dB filter at 40Hz

New version 2017-12-12:

• Windows setup and Windows portable (with JRE)
• Icon

Windows portable (.zip)
Other (.jar)

I have repacked Windows portable with OpenJDK instead of Oracle Java. It is also slightly smaller now.

Trying to install this on windows 7 and it fails ? Cannot find main GUI ?

 

[LightBit]

Thank you for reporting. I have tested it on Windows 7 (32 bit) without Java installed and it worked.

Please answer this questions to help me determine where the bug is:

• Did you have Java installed?
• If you have Java installed which version?
• Did SpeakerSim try to install Java?
• 32 or 64 bit Windows?
• Does SpeakerSim.jar work?
• Does portable (zipped) SpeakerSim work?

New version 2017-12-17:

• Listening window response graph
• Power response graph
• Directivity graph
• Excursion bug introduced with previous version fixed (it showed excursion at 1W)
• Java version check fix (possibly Xpandsound's problem)
• All files are smaller

It's ok I downloaded the pack you provided and everything works fine now. I previously only used the win installer (.exe) Going to try this 😀

Hello LightBit,

Does this software work with target curves and does it have an optimizer?

Is the active filter circuitry freely configurable or does it consist of pre defined filter blocks?

Thanks,

Eelco

 

[LightBit]

Does this software work with target curves and does it have an optimizer?

No target curves and no optimizer.

Is the active filter circuitry freely configurable or does it consist of pre defined filter blocks?

No, it is just pre-defined high level without any circuits (you define frequency, Q, and dB).

I just ran the Windows insaller package, set the environment altitude as 3 metres and got this error message;

I just ran the Windows insaller package, set the environment altitude as 3 metres and got this error message;

java.lang.NullPointerException

I cannot reproduce this.
You probably did something before that. Can you reproduce it?



If you can really reproduce it by only setting altitude to 3, try with debug build which shows more info on error and paste it again.

 

[Tromperie]

I didn't change anything else before changing the altitude. I tried it again and it didn't happen.

How would you suggest to model an aperiodic enclosure?

 

[LightBit]

I would simulate it as Bass Reflex with stuffed port (low Qp and probably also low Qa).
I would also use port calculator for vent dimensions (or for number of Variovents).


To make it typical aperiodic enclosure set frequency to frequency of closed box at that volume. Simulation will show you typical aperiodic low impedance at resonance.
