Passive line filter (Oris Horns)
Here a picture of the set, taken from de listening spot [img]images/uploaded/image378.jpg[/img]
Yes, that is the filter I am using, the input impedance of the bass filter is 100Kohm.The bass amps are Gainclones with an input buffer.The only difference in my set-up is that the crossover is located between my pre-amp and bass amps, the output impedance of the pre-amp is 1Kohm.
Mattijs de Vries advised to increase the resistors 20x for a better load of the pre-amp and the caps decrease also 20x to get the same crossover point. The pre-amp has a special bass amp output with an extra gain of 20db.
I hope you can follow the set-up
