Dear List,

We are working at an installation with four channel audio and a sub. 
Since the sub has not bas management  we would like to build an 
frequency-separating filter in pd at 85 Hz.
The cross over slopes should be as steep as possible. Has anybody ever 
implemented something like that?
What about hip~ and lop~, they seem not to have a very steep cross over 
slope, 6 dB per oct. We would look for something like 36 dB per oct.
