PCD & adding BSC...erg!

[krips]

I'm modeling a design in PCD. I got it so I had everything looking really nice, and all that was left was to add some BSC...I can't seem to get it to get back to a flat FR. Also, I want the BSC to stop at 1KHz as this is where the drop off stops on my baffle, how do I accomplish this? Thx in advance .

After re-reading my post I see that part of it does not read as I had intended. Of course I can't get it back to being a flat FR, and I do not desire this, but what I can't get is a flat FR after the BSC rise. I've tried padding down the tweeter more but that doesn't seem to help.

Most here don't use PCD. Best to ask at PE Tech Talk. You're likely to get lots of help, maybe even from Jeff B., himself.

Alright, I posted it there. Thanks.

Of course, if it isn't a software issue, but a how to design speaker issue, this is the best place to ask.

Fundamental flaw:

Try to add BSC as an after thought.

Design it in from the start. Proper measurements of drivers in-box will include it. If you're attempting to work in a pure simulated model, be model diffraction and baffle-step loss, combine, extract minimum phase, and be sure to set z-axis properly or it still won't work right.

d,
cjd, I am unsure of a number of things you've said. What do you mean by 'extract minimum phase'?

I don't design crossovers, but still try and be helpful. Are you following these steps:
