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 1: 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.
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 :)
