[QUOTE="Art Welter, post: 100332, member: 52"] Re: Help with EAW SM122's. As Ivan wrote "When you have several variables-it is hard to tell what is the issue". Why do you assume the differences are in the crossover rather than the drivers? Here is the raw response (no horns or crossovers) of four drivers purchased at the same time, all cleaned and diaphragms centered. They were all tested in exactly the same position. The differences carry through to whatever horn they are mounted on. A crossover individually designed for flat response with any of the four drivers will be wrong for three. The driver with what I consider the "most different" response of the four has the new "type 2" diaphragm, "type one" is no longer available. As you can see, the differences are about what your HF drivers look like. And LF drivers can go just as far off. [/QUOTE]
