I have an older Klipsch KSW12 subwoofer. There is a wooden ring that lays around the speaker. It apparently is glued on. It isn't secured with screws or anything else. It's fallen off of the speaker probably due to vibration over time. I'd like to reattach it but I don't know what kind of glue to use. I don't want to use just any glue and have it vibrate off again. If anyone could recommend a glue and/or a repair method for this I'd appreciate it. Thanks..
