Hey All

I hope you can help me in the right direction to find out what is wrong with my speakers. The bass response is completely gone from my right speaker.

The problem is not my tube amplifier, I checked its balance, bias etc, all is good, switching the speakers around the problem stays with the right speaker. Playing with the balance it is very obvious there is no bass output from the right speaker compared to the left.

Crossover schematic: http://www.jblproservice.com/pdf/Net...0A Network.pdf

I opened up the crossover and can see that the UHF driver is connected through a 3,3uF capacitor from the HF tap. The components I could measure without taking the components out measured fine and visually there seem to be no faults.

Any ideas on what to look at when the bass response is gone is most welcome.
