Xovers frequencies needed

[duffsag2468]

Does someone knows the cut-off frequencies of these two Xover
please? I want to use them on a new 3 way design.

That depends on the impedence of the drivers among other things. If the tweeter is 8ohms then the the xover frequency will be up around 5,000 cycles per second (5k Hz) but I suggest you spend a hour doing some basic theorectical work on cross overs. That will be time well spent as it will enable you to think it through and modify things yourself. The terms to look for are impedence of the drivers, frequency and the "order" of the filter. For instance the small resitor in the tweeter feed will almost certainly be unnecessary (or the wrong value) with a driver that is different from the ones this circuit was designed for. Mixing second and first orders can work but is a little unusual etc.

Sorry this is not more helpful but cross overs are something of a "black art" and very few people will respond well to the adaption of an existing design to a new set of drivers. Each unit has too many variables for this to work properly unless you arrive at a happy solution be shear chance!
Good luck. Jonathan
