Wayne, I notice on the 4 Pi crossover(for DE 250 ) that the schematic shows that the black post of DE 250 should be hooked up to the 1+ connection, while the red post of DE 250 should be hooked up to 1-.
Further, I notice that is just the opposite for the same crossover using PSD 2002. Does the DE 250 produce a forward wave when the positive signal is connected to the black post?
I was wondering, as I am using that driver in my Econowave speaker, and will be using it in the 4 PI w/ 2225H. I have found the DE 250 to be more transparent, but not very engaging for lack of a better word. Perhaps I need to flip polarity? Realizing it is already flipped in that second order crossover, so maybe it needs unflipped?
Confused,
Russellc
