First you have to remove the black plate on top of the bass unit. Below that plate you will find five screws. When you have removed them you can pull up the acoustic lens unit. Be careful: You need to disconnect the wires for the tweeters. Now you can pull up the front cover.

Thank you very much, I will give it a try ;-)

I managed to remove the cover and if I gently give the speaker a push 2 cm. above the center, I can hear a scratch noise, if I do the same 2 cm. beneath the center, no noise.

I think this indicate that the speaker Is broken, is that the correct conclusion?
Does anyone know the price of this speaker unit?

I`m afraid you are right. Do you notice the same noise if you (gently) press in the center of the speaker? And is there a similiar noise when playing music?

I don`t know the price of the speaker but at one of my BL5s the whole electronics module was changed. Price was about 250 Euro (omkring 2000Dkr)

Stefan

There is no noise when I press on the center of the speaker.
The noise is the same as when I play music, but I have to turn the sound level up to about 70, before the noise is there, depending on the music.

I think I will order a new unit (har en kontakt i Struer).

Yes I think you will need a new one.

But the BL5 will have to be calibrated to the new speaker. There is an eeprom that has to be changed... (?)

Thank you for your help

Stefan, I have sent you a PM

Sounds like the voice coil has gone off alignment.

I've never heard of any problems with damaged cones in BeoLab 5s. I'm almost certain it'll need to go back to B&O to be properly re-calibrated though. It's not like some of the other BeoLabs where you just turn a little pot - all digital here!
