I'm trying to track down a subtle problem with a pair of 3way passive professional speakers. I'm getting a subtle variation in frequency response and I'm trying to determine whether it is in the crossover or drivers.
I've ruled out the source/amps. I've swapped tweeters and this was inconclusive, swapping mid range units is difficult but possible and I can access spares.
For my own peace of mind I'd like to measure the crossovers and I know this will be difficult because of the typical low impedance of drivers and the 10k input impedance of my measuring gear (REW/Fuzzmeasure and pro DAC/ADC).
I don't need to measure the actual response of the circuit, just to isolate any differences between the sides.
Before anyone suggests measuring the whole rig acoustically I've never found this to be satisfactory when dealing with small and repeatable differences, I have recent experience on an install at a world famous studio where we could blatantly hear a difference that we could not measure.
Any suggestions?
