My little Bandpassfilter

Not open for further replies.
This is my little Bandpassfilter for one Sub output and one Highband Speaker with differantial Outputs:

For the Sub Bandpass the Frequenz is 120Hz till 1100Hz.
And for the High Bandpass the Frequenz is 900Hz till 30000Hz.

The frequencies are adjustable through the Rs and Cs in the Filtersections.

Im just using some 13cm W 130 X - 2 x 4 Ohm as a sub.
I orientated me on this frequency chart for my sub speaker: At 2 ohm
An externally hosted image should be here but it was not working when we last tested it.


and for the highband i will use some coax speakers.


This is just an design and i realy have to test it, the pcb's are on the way to me and i will see how this will sound...

Also i can realy adjust the lowpass and highpass frequency for every channel. I just have to use other values for the Cs and Rs.
