Simply Speakers 5 Inch Foam Speaker Repair Kit for JBL Speakers - 3-3/8 Inch Cone, FSK-5Ji (Pair) - Perfect for Home Audio and Studio Monitors

I had very little problems installing these replacement surrounds. Where I did have slight problems was in gluing the surrounds to the woofer cones, and it was due to just a bit too much glue in a couple spots. In reality, if you're not picky about appearance, the tiny little bit of glue that was beyond the overlap of the surround until I cleaned it off was not going to cause any problems.What you want to keep in mind as you look at the lower ratings from some reviewers versus the 5 star ratings, is your own personal level of touch and skill. If you're not a DIY type, if you've never repaired or assembled anything using glue, or you just tend to be clumsy and/or are not very bright, replacing speakers surrounds is NOT something you should be doing. If none of the above applies to you in an honest appraisal, you should not have problems doing this repair.Once you start gluing the surround to the cone, do NOT attempt to pull it all the way back off. Make sure you get a thin bead applied fairly evenly around the entire surface, both for surround to cone and surround to frame. Trying to lift up part of a surround of this size in order to apply more glue is only going to get you into trouble, so get the glue applied evenly from the get go.Lastly, keep in mind that the glue will take some time to get tacky enough to hold the bond. This is why in the videos it shows the guy doing the repair going around multiple times gently pressing the surround into place. This is where touch comes in, and even if you were able to get an even bead of glue, if you have the touch of a blacksmith or something similar, your repair will not end well.
