In Reply to: A short study of crossovers posted by bobwire on April 10, 2002 at 08:22:01:
A few quick questions:With a 2nd order crossover, you invert phase, right? If so, do you find this annoying, or do your just invert signal in the chain? Have you tried 3rd orders with your model?
How do you do your impedence compensation? Any sites or pointers? I am not doing any speaker projects now, but might in the future.

These were all computer sims so I did not ivert phase. As for doing imp-comp, I use a audio generator (HP3310A) that I hold at 1 volt output through a 1K resistor (1.000K) monitored with a voltmeter. I use another voltmeter to read the voltage across the voice coil, this meter reads out as ohms. So that 6.4 milivolts for instance is 6.5 ohms. bobwire
Once you have the true impedence graph of a given driver, how do you compensate across the entire frequency domain that the given driver should cover (in a crossover design)? Do you average?
