 I know this is a pretty small minority but here goes.
Does the bass in your Bang and Olufsen Red Line speakers sounds a bit wrong? Maybe it can resonate at higher volumes, you hear rattling when moving them, or the bass just doesn't give that kick you usually had. Or maybe you know the ABR is knackered but don't know what to do without burning your wallet.

If you want an easy way to repair your ABR then read on.

Step 1Tools and possible parts

Tools and possible parts
This could depend on how badly damaged/degraded your ABR is. If the ABR plate has just fallen off the foam/cloth all it needs is glueing on. If the foam/cloth has degraded to nothing you will need to replace the it.

Tools:
A philips medium sized screwdriver.
Glue for reattaching the plate to the foam/cloth.
Sand paper to ruff up the plate for ease of glueing.
A place to keep screws so you don't loose them, a small pot is ideal.

Tools and parts needed if the foam/cloth has degraded:
A new sheet of foam or cloth similar to the stuff the was there to begin with. I suggest a cloth similar to the cloth on the front of the speakers.
A sharp knife for cutting the foam/cloth.

A clear well lit work area :)

Hi man really comprehensive and may well come in useful. I have just got a set that are on their way to me. However the speaker cloth on the front isnt in great condition. In your dismantling did you notice if it would be easy / possible to replace the cloth

Thanks Tom

 Hi Oscar
I got mine from Ebay as well paid 90 for them, they are the 45.2 version. I demoed the 60.2 version but they were a bit pricey. I will have a look and see if it looks possible to replace the cover as mine have a few nicks in them

Great set of instructions but when I took mine apart the plastic bands fell apart. Do you have any tips for what can be used to replace them?
