BOSE Speaker Vibration Parcel Shelf

[Saff]

Revival of an old thread. My D4 developed a buzzing (farty) noise from the rear central subwoofer. Removal of the grille revealed the speaker central dome was coming adrift and vibrating at certain frequencies. I bought a used speaker unit from Prestige (great service as usual) and today attempted to change them out. We took the upper boot trim out with a view to bring it out that way but there was no way that could be done. To take it out would entail removing the parcel shelf which appears to be a massive job. We decided to try dribbling flexible super-glue around the rim of the dome.It appears to have worked. We'll see if it lasts. I have the replacement if push comes to shove. Fingers crossed. Hoping this may help someone in the future.
