Baffle step compensation formula?

bart_dood · 4th July 2006, 05:52 PM

Hi guys,

I recently built a couple of speakers using tang band 871's (3inch) and I have read about adding a baffle step filter to them, but I can't seem to find a simple formula for working out the filter values or a schematic.
My speakers are 6 and 3/16" wide and 11 and 1/4" tall, the driver is mounted in the center at the top and I have a port at the bottom.
Could anyone tell me what kind of baffle step filter I need or the values? Or perhaps point me to a website with some reasonably easy formulas to work out one?

thanks!

You should try The Edge .
It's a small program that let you simulate the effects of
baffle step and also suggests a suitable correction.

Even easier -the Excel file here. http://www.quarter-wave.com/General/..._Articles.html And Martin doesn't put up anything that isn't worth having.
