Dr. Brown's AR2s Posted February 24, 2020 Report Share Posted February 24, 2020 I have a woofer rattle in one of my mid-60's AR2s. I've pulled the woofer from the cabinet to make sure it's not something in the cabinet and I still get a rattle. I've inspected the woofer basket, surrounds and the spider and it all looks good...nothing loose, no tears, no much deterioration that I can see. Do I need to cut the dust cap and peel it back some to inspect the voice coil? Any other suggestions? Thanks! Quote Link to comment Share on other sites More sharing options...
LouB Posted February 25, 2020 Report Share Posted February 25, 2020 Check to make sure that the masonite ring the spider is attached to hasn't loosened from the basket. I have experienced this on more than one original die cast 10" AR woofer. If yours needs to be repaired, be sure the voice coil is centered..... I re-adhered them with slow set epoxy.

Dr. Brown's AR2s Posted February 25, 2020 Author Report Share Posted February 25, 2020 Thanks LouB, I'll double-check that. Would you recommend cutting the dust cap to see if the voice coil is properly centered or has any debris around it? Quote Link to comment Share on other sites More sharing options...
LouB Posted February 25, 2020 Report Share Posted February 25, 2020 If you do remove the cap you'll be able to visualize whether the coil is centered if you do have to re-glue the masonite ring.. There are different techniques people have for centering it if necessary, maybe the others here would like to share their personal favorites.

RoyC Posted February 26, 2020 Report Share Posted February 26, 2020 The rattle is a common issue with these woofers, and is almost always caused by loose masonite rings under the surround and/or the spider. see attached photo. Roy Quote Link to comment Share on other sites More sharing options...

xmas111 Posted February 26, 2020 Report Share Posted February 26, 2020 I had the same rattling issue with my AR-2ax's several years ago. As it turns out it was the spider coming loose from the basket. Roy's picture show the same thing I found with mine. Here's a picture of what mine looked like.
