Simulate Xmax on Win ISDpro

[Augusts]

Hy
A big thanks for the possibility to ask these questions, I hope I am not annoying anyone by asking this, but I cant seem to find an answer on my own.

I am now triing to simulate the cone excurcion for some drivers and the results I get seem to be somewhat ridiculous

the driver is BMS 12c262
this is what I get when throwing the rms power at the driver that is 400 watts.

so this would be not exceeding xmax - 54w. I think this is insane for a PA coaxial driver.

What could be the error in all this, I might have misunderstood something, as I have not studied speaker construction nor enclosure construction, nor do I probably know all the nuances of this process that I am gooing throught

Thanks
A

That driver is not designed for low frequency reproduction... that has been compromised for higher sensitivity, so really this unit is only suitable as a mid/high component of a larger system or for relatively low power "fullrange" sound.

Try a sealed box and aim for a roll-off that mimics a 2pole Butterworth (B2).
See what frequency that comes out at. and then decide if you could use that with a dedicated bass only speaker.

Thanks, guess I got rid of a lot of illusions.

The speaker is now crossed at 250 hz, works well

Thanks
