crossover advice please

Hi guys,

What do you think of using a 2th order Linkwitz-Riley at 2200Hz. That way, I'm 2 octaves over the tweeter Fs(550) and a little more then 1 octave under the point where the drive SPL start to decrease(5000Hz) ? I plan to use a tweeter L-pad and a EQ for the driver to remove the impedance spike around 4kHz and 5kHz.

Thanks,

Thanks for the links.

What's bad is they all use the Vifa driver but with different tweeter then the one I have.

I'm just not sure witch crossover point to choose and how to accurately choose it.

Thanks,

Hmmm.......

you could do a lot worse than using this as your starting point :

c/o point is 1.75Khz L/R 4th order acoustic

Substituting a tweeter is a lot easier than starting from scratch.
