I just replaced a broken diaphragm in a Beyma CP25 tweeter.
It seems to have stronger output than the left channel with 10 years old diaphragm.
Is it a case of new versus old and should I replace the second one as well, or did i do something wrong when I installed the new one?
I remember there was a very very small amound of "goo" (rubber celment?) under the phase plug of the original diaphragm. I thought first it was holding the phase plug in place but as it turns out, it's the horn that maintains everything together once it's bolted on the magnet assembly/diaphragm.
I don't hear distortion, it just seems a bit louder and seems to shift the stereo image slightly to the right.
Different impedance maybe? Measure the DCR and see if it is much different. Anyway, if they are no longer balanced, replacing the other one is the best option.
I'm not sure but I have the feeling the difference is less now after a couple hours playing. Maybe there's some kind of breaking in going on?
I will see how it turns out after a few more days.
Right out of the box it almost sounded like I had changed something in the crossover.
