    I noticed that the horn in one of my SWR Goliath 3's is not as crispy as the other. I took out the tweeter to examine and it looks fine. I also did the crank the highs and master, rotate the attenuator and you can hear the highs increase, but not very much. I'm wondering if the L-Pad is going out. I have continuity between all connections in the circuit and everything seems to measure as it should, fuse is good. How can I test L-Pad?:help:

    Should get not only continuity, but test 8ohms or close to it throughout the range of the dial.

    Did you take your tweeter apart and look at the coil/diaphram? It could have a burned spot that doesn't totally incapacitate it, but causes problems when heat comes into play......meaning it could test good cold, but still not work right.

    I swapped the horns and they are fine, it has to be the l-pad. Thankfully, they are only $10. Fingers crossed that this fixes it.
