I want to change the cross over frequency of an old 2-4 naxo to 160hz. I have found a good calculator for the low pass section at Dimensioning of Active 3-Pole Single Stage Low Pass Filters but have not been able to find one for the high pass filter section. The problem is that the Naxo is a three pole single stage design and the only online calculators I can find are for three pole two stage designs. A circuit diagram is available at Neil McBride's HiFi Stuff Can anyone help a non techy DIYer ?
