Hi and good morning all
ive aquired a pair of B&W DM305 Floorstanders and 1 of the prism back panels vibrates at certain bass frquencies ive taken the driver out and can see that B&W only glued them top and bottom of cabinet to the prism piece and not to sides which seems to be where the vibration occurs ive taken a pic of original glue but not sure what it is or what i could use instead to reseal the sides inside to try and stop vibration. Obviously i need a longish nozzle to be able to get inside cabinet and reach past prisms to reach sides.
Any help would be appreciated

I would clean the roughness off the chip board first and then use RTV silicon sealant to hold anything loose together. It is reworkable and stays semi flexible, unlike hot glue.
thanks JonSnell i was hoping someone would pick a more flexible option as that hard glue in there looks a terrible idea.
Gluing backs in place wouldn't be my style at all. Gasket? More screws?
Endless debates about panel vibration with no evidence it matters audibly in the least. We all hate to feel the vibration; maybe all we need is anger management not bracing.
BTW, when you are in the box, might as well re-write so you can have a tuture choice to eliminate the stock passive crossover (with the elderly and likely defunct capacitors) from outside. You can use an externally mounted passive XO or much better, DSP XO.

You can't remove the backs as there glued in and trying removing that will ruin the chipboard cabinet so cannot see how to use gasket and screws
The repair of sealing / glueing must be done in situ tbh
I did think while there out to change caps, I've already priced them up
We must think alike 👍
