It could be just a rumble or other interference that stopped the calibration from being completed. Worth checking out - and yes, taking a BL5 "apart" is a task. I've had the skirt off to look at the innards.

I will try it again when I get a chance.... maybe after moving it. Hopefully it's nothing too big because it would be 6 months out of warranty. boo. They still play perfectly though so I am not too concerned.

Hi, you could try this. Its the B&O factory hard reset. Press and hold the field sensors for 20 - 30 secs. You will hear a distinct POP. This sequence takes the speakers back to factory rest values.

My dealer whenever he comes over to my place (about twice a year as I have just bought the B&O BS3 & Projector  System) and moves the speakers about, he always does a hard reset.

Hope this works for you.

Hey thank you for that. I might give it a go.

The only problem could be that the calibration did work when we first set it up. So it would lose those settings. Hmmm decisions decisions.
