Theo Wood Posted February 12, 2019 Report Share Posted February 12, 2019 I recently picked up a pair of AR12 Speakers and and every once in a while one of the midrange's gets a buzz/crackle. I tapped on the cabinet and it goes away. The midrange does need a new surround. I haven't taken anything apart yet. Other wise the speakers sound absolutely incredible. Just wondering if anyone has encountered such an issue. I would like to know what's going on before I go thru the effort of putting a new surround on it. Thank you.

Aadams Posted February 12, 2019 Report Share Posted February 12, 2019 A photo of the mid would be helpful. By "tap" do you mean "whack"? Link to comment Share on other sites More sharing options...
GD70 Posted February 28, 2019 Report Share Posted February 28, 2019 Test the one that has the buzz/crackle first, outside of the cabinet. It's mounted to it's own cup enclosure that comes out with the mid attached to it. I suggest just pulling both mids and refoam them regardless unless there's an issue with the one. It could be old ferro fluid that needs replacing. I was lucky that mine were very soft and the cones moved freely when I refoamed them.

Theo Wood Posted March 1, 2019 Author Report Share Posted March 1, 2019 I haven't had the issue since so all is good now. I will go ahead and install the surrounds when they arrive. I'm still in awe of the sound these speakers produce. Feel very lucky to have stumbled onto them. Link to comment Share on other sites More sharing options...
Theo Wood Posted March 9, 2019 Author Report Share Posted March 9, 2019 The problem arose again. I'm a little embarrassed to say that it was actually the woofer having the problem. An intermittent scratchy sound only noticeable at low to mid volume. I took the woofer out and found one of the terminal connectors on the woofer very loose. I just pulled the connector back a little so it was tight and it's been good since. Link to comment Share on other sites More sharing options...
GD70 Posted March 30, 2019 Report Share Posted March 30, 2019 Good to hear it wasn't anything serious! You get the mids refoamed yet? Link to comment Share on other sites More sharing options...
