Hi- having a new issue with a speaker and seeking advice on whether to attempt repair myself or find a local servicer. I have a pair of Heresy IIIs that we have enjoyed for maybe 6 years now. Just today, one of the two speakers started crackling/popping sounds sporadically. I checked and reset all exterior connections and swapped the speaker wire with the one connecting to the opposite speaker, and the issue continues, so I think it’s something internal to the speaker. I removed the grill and noticed that I can trigger some crackling when I press around the edge of the woofer. I don’t currently have the right size hex driver to remove the woofer and not sure whether I should find a driver first and try to open it up myself, or find a local repair shop (never messed with a speaker before, but definitely want to repair this one). Appreciate any advice.
