Re: Help with EAW SM122's.
Marsellus,
The response differences look more like driver than crossover differences.
The original spec is +/- 3 dB 80-18 kHz, your monitors range about +/- 5 dB worst case.
For old (cheap) drivers, another couple dB off is not unusual.
I have four monitors with old drivers with similar differences as yours, and I built the crossovers with new parts.
When building the crossovers, I had considered making individual part adjustments to compensate for the driver differences, but decided against it, as diaphragm replacement would change the response again, and the "old style" diaphragms in 3 of the 4 monitors are no longer available..
I just numbered the cabinets, and use them with EQs set to the inverse of the response difference, done.
