hi I am new to this bb. I recently bought a pair of the tangent 300 speaker and I wanted to upgrade it's crossover. Does anyone here have the circuit diagram for the crossover ? I opened up one of the speakers today and found out that the inductors have no value stated on on them and also there is one capacitor ,a small one with no value , looks like thos 0.1 uF paper caps. Anyone can help ?? Thanks Anthony
