Active filters? (Off Topic)
Hallo!
To my experience, electronic x-overs with too much of possible adjustments tend to degrade the sound. For example: All the filters are constructed to operate in a wide area, which causes automatically some internal impedance problems.
I used the passive filtering, as suggested by Bert for the Bd-15. That worked quite well, but due to the low input impedance of my bass-amp, I had to make some compromises.
Now I use an active x-over from Thel audio Germany. That one has the advantage of a narrow but very fine adjustable range. The basic range like x-over frequency in the range from 200- 500 Hz ist selected by soldered capacitors, the fine-tuning is done by swithchable Resistors.
I use that x-over only for bass, midrange/trebble is filtered with passive components.
For myself, I´m satisfied with that system.
Best regards
Stephan
