In Topic: Crown XTI 1002 as active XO and amp

Thanks for the replies guys. Ive been away a couple of days.
Anyway, i have read a ton about crossover design now and realize i should have had a better understanding of the basics before i startet this project. The speakers are fully active with no internal crossover. Separate connections to lf and hf. I do use a cap in series with the tweeter to protect it I connect lf and hf wrong some time in the future

The tweeter is a really expensive tweeter that should not be harsh (one of the few?). But my lack of understanding the basics of speaker design got me in a pit with regards to soundquality.

What I did wrong.
- i did not measure the tweeter and woofer separatly with a mic to find a good xo point. I thought it should be 1250hz, when 1800 was much better.
- i did not understand about step baffle comp. Failure to identify where this should start and include this gave me way too much treble. I had to use high shelf filter on both channel 1,lf, and channel. 2, hf to achieve this. Is there a simpler way?

After listening test now the harshness is gone, and my only concern is some resonances at a frequenzy oround 500hz. I think this can be solved with more stuffing in the cabs. I do have just a little stuffing in them now.

Some written guidelines to how to use the software to design a good crossover is deeply missed.
But now the speakers are really starting to sing :)
