Cone Displacement

Dayton Audio RSS390HF-4

Dayton Audio RSS390HF-4

Fs: 19.5 Hz, Vas: 212l, Qts: 0.43

Dear all

When i'm modelling an Dayton Audio RSS390HF-4 in speakerboxlite , i doesn't reach the maximal cone displacement.

Doing this in WINISD i have allways the problem with the same datas that the cone displacment going out of limits, which is normal with avented box design.

How accurate is speakerboxlite in the cone displacment graph?

please have a look to the graphs.

Same with port velocity

here the graphs

Maybe you specified different powers? For example, for SBL it was RMS power, but for WINISD max power?

Thank you for the comment

With speakerboxlight i have only the possibility to enter the Pe = 500W

With Winisd i used the system input power =500W

Any other workaround for speakerboxlite?

I'll try to look on Sunday. But I don't have WinISD I have the BassBox app to compare.

This is my last project: https://speakerboxlite.com/project-info/13613/tab-info - simulated in WinISD, i wrote very long description for it (in the "Project link", because the shared project's description-textbox was not enough for that), and there are screenshots of WinISD graphs / data in project's gallery. Maybe this helps a bit... Btw, I noticed that at closed and vented boxes BassBox app's simulations are very similar like here on SBL (at least for those woofers which I've tried to simulate in both simulators), the bandpasses and PR boxes I didn't tried yet.

I'm sorry for the late response. I was busy and a little sick. I compare SBL results with another program and the results are the same. I think all correct.

I know BP6 has some issues in their graphs :( I hope I'll solve them in the next year when I'll updating computation formulas.

Thank you, it seems that Winisd isn't correct
