Question How to calculate baffle step?

Hi all,

What is the best method to calculate baffle step, and to design baffle step compensation? I'm working on 2 designs: One with 2 Peerless HDS 6,5" in a MTM configuration, and one with HDS 5" in a MTM configuration. The tweeter in both designs are SS 9500.

Thanks!

All the best,
Henrik

ESP has an article that describes it well

It includes a formula.

True Audio also has a helpful article with formulas

You may also find Baffle diffraction simulator or crossover simulator (which includes bafflestep) at the FRD consortium to be very helpful.

You could try my little baffle step response calulator "The Edge".

Great application!!!

I'm a rookie speaker-designer, and applications like that are perfect, i.e. not complicated , for my level of understanding. How do I make a calculation for designs with 2 woofers?

Regards,
Henrik

Hi Svante,

I can see that you can do that, but the application places the second driver in the corner of the baffle, and I have no way of specifying the exact location. To my understanding, because of that, the calculations are not correct. Is there any trick I'm unaware of?

Regards,
Henrik

I think you can drag the drivers around with a mouse, using "click-and-drag".

Well, Charles said it before I got to it. BTW, you can drag the corners too if you want a strange shape for your baffle.
