mikepick Posted July 9, 2019 Report Share Posted July 9, 2019 I am working on a pair of Smaller Advents and one of the woofers has a sort of soft distortion, like a buzz, but not a harsh sort of sound. I'm going to try and add it to the thread as a recording but for the moment I'll just try to describe it. I bought this woofer from the auction, it was sold with a new surround on it. It looks good, visually, the spider has no irregularities and the cone is intact. The tinsel wire seems solid, and there is no rub from the voice coil when I press it down. The distortion is more noticeable at low volumes, and it gets masked as you raise the volume. As a background, I've been doing some speaker repair and have replaced surrounds, but am a relative novice. I pulled the woofer from the cabinet and have done some feeling around with it playing on the workbench, and the one thing that solves the distortion is pressing my fingers lightly on the dust cap. pressing the surround in also stabilizes the sound, but the dust cap had a much more noticeable effect. Does it seem plausible that the dust cap might need to be removed and re-glued? I don't know how the new surround was attached, I just put a new surround on one of these spit-cap woofer and did not need to remove the dust cap. I may just cut the dust cap out and clean it up to see if it makes a difference, as it seems I have little to lose. Thanks, Mike Edit: I am trying to add phots, but it gives me error 200. Visualize a nice looking spit-wad woofer. Quote Link to comment Share on other sites More sharing options...
