Default Help with active crossover

Hi,

If I need to put an L/R active XO with baffle diffraction compensation (bdc) & a linkwitz transform (lt). What would be the order to wire it up. I understand the LT requires a low source impedance so should I place that just after the input buffer, or should it be the BDC first, followed by the LT & then the main filter.

Thanx,
sunil

I have not used the linkwitz transform, but from what I know all active filters need a low source impedance to maintain the filter shape as frequency increases or something like that.

I have in my actives the filters, followed by level adjustment.

Then in another one filters, notch filter, BDC, all work well.

So, can I put the input buffer followed by the linkwitz transform, the BDC & then the filters.
Will putting the linkwitz ahead of the others affect the setup in any way ?

cheers,
sunil
