chrispaul67 Posted June 9, 2014 Share Posted June 9, 2014 I have a pair of Klipsch 4.5's I purchased years ago. Shortly after purchasing them I noticed some odd noises coming from them during loud passages. I found that the back panel of both speakers was vibrating and were coming apart from the speakers. I haven't used them in a while and I would like to again but I would like to correct this issue. What would be the best way to fix this problem, and is this a common issue with these speakers?

Cal Blacksmith Posted June 9, 2014 Share Posted June 9, 2014 I bought a pair of them for my son to use in the navy. They had the same rattle in the rear which resulted in a nice discount for me from the seller. I removed the drivers and insulation then I cut some 1x1 strips to frame in around the inside of the back and glued them in. I cut other strips of 1 x to use as wedges to keep the reinforcement in place while the glue dried. The result is that the rattle has been entirely removed and all it cost was a couple of bucks. Once the glue was dry, I removed the temp braces cut to act as clamps and put everything back where is belonged. All has been well for the last 3.5 years now. They got some pretty heavy workout when the son was in the navy and they are holding up just fine. 1 Quote Link to comment Share on other sites More sharing options...

I clamped the speaker best I could, used the wood strips with TiteBond 2 glue and let it sit for about 18 hrs. No more rattle. Very common problem. Hot melt is what they used when they abandoned screws and it breaks down over time. If your rear board is loose all over you might have to pull it off gently and re-glue the whole thing.
