Default Active High-pass filter for Horn Subs

Hi all.

I don't really have time to 're-invent' the wheel, but does anyone have a good active X-over highpass filter design in the L/R 24 dB range

I've just finished building some Folded Horn Subs and need to prevent over excursion at lower frequencies.. ie about 40Hz. The exact cut-off freq isn't crital as I can change that.

Thanks,


Ed

Here's an all in one that is high pass, low pass, boost and attenuation.

Elliot Sound Products (ESP) runs a website that has an enormous library of theory, design and build information.
Go into his index and find the project/s that give you the high pass filter you are asking about.

The Reckhorn stuff is of quite poor quality as statet in several german forums. Better follow AndrewT´s suggestion.
