HI a long time ago I changed 2213H which had deteriorated suspension with a 123A-1 believing they were interchangeable.
Now I have discovered that 2213h is a negative transducer and 123a-1 is a positive transducer.
What should I do now since the crossover is original... reverse the cables that come from the cross over behind the 123a-1?
or you have to change the cross over ??
someone can help me technically

thanks luigi
