Charles218 Posted August 25, 2007 Report Share Posted August 25, 2007 On several occasions in the past couple of months I have heard a strange sound coming from one of my speakers. I removed the grill this morning to discover that the cloth surround has come unglued from the basket. How do I proceed to remedy this? Do I need to just apply some glue or are there other steps that I should take? What kind of glue should I use? Link to comment Share on other sites More sharing options...
johnieo Posted August 26, 2007 Report Share Posted August 26, 2007 >What kind of glue should I>use?Parts Express sells a small tube of white glue (Latex, I believe) that is sold for attaching foam surrounds. I have used it to attach a loose cloth surround. One can lift the loose edge carefully with a thin blade or toothpick and work a drop or two under the loose area with another toothpick or something like an exacto knife or scalpel, then clamp it until it dries. Paper clamps (springy black with wire handles) from an office supply store are handy for that job. As you are likely aware, it is best not to use the driver until it is repaired. Without the air suspension the voice coil could bottom and cause serious damage.Cheers, Link to comment Share on other sites More sharing options...
johnieo Posted August 26, 2007 Report Share Posted August 26, 2007 Sorry, if the woofer is in the cabinet, I would lay the speaker face up and after applying the glue, put a small deadweight on the rim to clamp until dry. The spring clamp is only useful on woofers that have been removed from the cabinet. Cheers, Link to comment Share on other sites More sharing options...
Carlspeak Posted August 26, 2007 Report Share Posted August 26, 2007 If your surround is only partially unglued you probably won't have to concern yourself with voice coil alignment.If it's completely unglued around the entire periphery, then you'll need to check for VC rubbing after you apply all the glue and secure the surround's edge to the frame. The white glue dries slowly, so if you hear rubbing when you gently push down on the center of the dust cap you can take action to separate the surround from the frame and attempt another centering before clamping.Agree with John O's suggestion about laying the speaker on its back if it's still in the cabinet. This will also help the spider keep the VC centered in the air gap.Suggest you also check the other woofer for the same problem you raised.It's all about the musicCarlCarl's Custom Loudspeakers Link to comment Share on other sites More sharing options...
Charles218 Posted August 26, 2007 Author Report Share Posted August 26, 2007 John & Carl,I appreciate your input on this and will proceed with the repairs. Fortunately only about one half of the ring is loose so the unit has stayed in position. I have glue left over from a foam surround project, on my Dalhquist, that I purchased from Simply Speakers.Charles Link to comment Share on other sites More sharing options...
