Hi, I recently bought a pair of Beolab 18's as rear speakers ( 9's at the front, working with a BV12 ) and have an intermittent popping sound coming from them. I had B&O service team out but of course there were no issues when they were here but next day I got the popping sound again and now most days it happens. The speakers are connected wirelessly to the system.

Any advice or guidance on what I should try to resolve ? Is this an issue with wireless connectivity ? Also, I am wondering whether it is related to the power lead as the speakers are right by the sockets ? But really I have no idea hence the request for help.

Many thanks in advance.

Record a video for them with the sounds so it is visible and audible in your home.

Is it one popping during switch on ore more often?
Or is it switching on and off and does this sound?
Does then LED Change colour?
Both Labs or only one?
If both are popping, same time or different?

Hi, The popping is ongoing on both speakers and not just when they are turned on. It is also intermittent ... Does not always happen and will start / stop at various times whilst operating. I do not see the lights changing color when it happens.

I have tried switching between 3 and 5 speakers to see if that helps but it does not ... No popping when set to three but when I switch back to 5 the popping comes back.

 

Thanks.

Hello Neil,

I do have a similar sound on my rear BL12.

Mine are connected with CAT7 wires. do you already have a solution for your problem?

 

Thanks, Heribert

It makes me think to something related to your electricity installation. You should try to connect your BL to some surge protectors to avoid any power variation which can makes popping.

Does it appear too when switching a light on or off in the same room (ideally same wall where the BL are connected) ?

does the popping sound only happen when you use the remote?

if so it maybe data signals are finding there way onto the audio signal.

Check the ground of the cat 7 and interconnects.

It could be an issue  with 4G interference ,not sure if  beolab 18 have them incorporated!.but a filter may solve the problem?!

Heribert, I had the B&O service team out last week and thought they had fixed the problem by changing the output used on my Beosystem 3 for the speakers as the issue went away.

However, a few days later the problem came back although it is happening less frequently now and only when I initially turn the system on.

it is very frustrating and I will probably try a surge protector as someone has proposed to see whether it is the power supply somehow.
