captainbeefheart Posted November 26, 2021 Share Posted November 26, 2021 I hope this finds itself useful for the folks doing work on Klipsch crossovers. I can simulate other models as well if there is an interest, I did the AA network because it seems to be the most popular for heritage models. Pictures are in the order like the schematic from top to bottom; 1) woofer 2) mid 3) tweeter Viewing them in this order you can see how they overlap each other to cover the whole audible frequency range. This is how I test crossover networks, I place the signal generator output to the input of the crossover, I then put resistive loads on each output and then use a frequency analyzer to look at and compare the frequency response of the networks to make sure they are functioning properly. This gives you a great indication of which filter is having a problem so less time taking the whole board apart and testing each component. I also leave my scope on the outputs in chop mode and compare to the input, sometimes you will see an ugly waveform at the output with high distortion, a good indication a component is toast. 1 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted December 11, 2021 Share Posted December 11, 2021 If you will adjust your load impedance, you'll get more accurate results. Woofer - 6.3 - 6.5 Squawker - 12.5 at 400 Hz Tweeter - 8 ohms (7.2 DCR) Your model does show the EQ built into the tweeter filter. 1 Quote Link to comment Share on other sites More sharing options...

Yes, and that the AA tweeter filter is near full power at approx 5000hz, not 6000hz. 1 Quote Link to comment Share on other sites More sharing options...
