Schematic Diagrams of Crossovers for Jensen Imperial Speakers PR-100

[dungtran987]

I have an old pair of Jensen Imperial Speakers PR-100. I would like to build/restore the crossovers and the equalizer of the Jensen Imperial Speaker PR-100. Do you have schematic diagrams/link of the crossovers of this Jensen PR-100 speakers or any idea about how to restore them.

Any advice or recommendation is greatly appreciated!

Hi dungtran, do you still have the Imperials? I just picked up one for a mono system and I'm going to attempt to rebuild the crossovers.

Thanks streetwise! Any info on the inside of the M1131 equalizer?

Yes 1.6MH inductor, 8uf cap, and im guessing 20ohm resistor. In the picture with the Jansen SP in the top left corner; The M1131EQ is most likely the parts in front of the mid out. I collected all these pictures from some Japanese websites using google search.

That’s it! Thanks streetwise. I got the parts for the 2 crossovers. Looks like one more order in my future for these items. Hope to get this all together in the near future.

Did rebuilding the crossovers make a big difference?
