Active High-pass filter for Horn Subs

[Eddie Wolve]

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.

ESP shows that high pass filter.

Hi Andrew.

Not sure what you mean here mate.. Can you give me some more info..?

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.
