[QUOTE="Art Welter, post: 100062, member: 52"] 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. Art [/QUOTE]
