Simulation of current thru the driver

[wonderfulaudio]

Hi,

I would like to simulate the current thru the driver for a closed box and bass reflex. Are there any (free) tools that can do it? I tried WinISD and Hornrespons but they dont.

Thanks and Regards,

What would you want to know exactly? The electrical impedance graph as calculated by both WinISD and Hornresp tells you about the current. Just divide the applied voltage by the calculated impedance. Note that the impedance consists of both a magnitude and a phase.

Use the Maximum SPL settings shown in the first attachment and then sample the response. This will enable you to find the current at any frequency, for an input of 3 volts.

Cool. Just what I was looking for. Thanks.

David,

Voltage, current and impedance, only 2 can be fixed whereas the 3rd will follow. So, if I specify just the current and leave out voltage, I get current limited max spl? Pls confirm.

Thanks,

Correct.

I forgot to mention that alternatively, you could simply export all the chart data, which includes the input current values.
