I bought a new computer last year and I lost the crossover document, so could you send me another copy? Plus the one I used to have did not have the 1khz and 1.2khz crossovers.
Thanks!
By the way, I hope you don't mind, but when on my other forums(audioheritage and audiokarma), I usually reference you when describing my systems. Also there are some who need crossover help and your crossover document has a lot of good info in it which many folks appreciate.
I have found the 2nd order lo-pass and 3rd order hi-pass crossover topolgy to mesh very well with horn systems.
My other favorite is 1st order with horns and amps less than 3 watts. It is not a exact science though, I have found that actual listening and swapping caps and coils to help fine tune a system that is in a restricted acoustical environment.
Another of my "breaking the rules" is using a 16 ohm compression driver with your crossovers without changing R1 and R2 along with the HF comp cap. Then I swap a component and listen until I have listened to the range of values for the best result. I usually don't vary more than 10% of the original values, and less than 5% is I change more than one value.
With those little tweaks I have been able to make up for my rooms faults sometimes with great success.
Regards, Ron
