I had this issue since almost beginning.

After I moved to new house it was a real battle between my wooden floor (which is normal) and a speaker ;)

I loosen all front screws a bit and it seems to be fine now. I’ll see for how long...

PS. I find the customer support useless in Poland. I didn’t even bother sending the speaker to them.

This solves it.

It's the warping of the plastic materials that creates the popping sound.

Loosening the screws underneath the cover will solve it.

My A9 mk4 have started making these clicks and popping sounds. It is weird since I have had the speaker for about 6 months and not noticed the problem until now. Summer is fast approaching so perhaps there is something to the temperature theory some have pointed out.

• Has anyone else experienced the issue on mk4 I actually thought B&O had sorted it out in the later models?
• Perhaps it is a stupid question; but if I loosen the screws underneath the cover will the plastic front chassis not become loose and affect sound? Surely that is not a viable long time solution?

Hi!

Loosening the screws will not cause any problems. 
It does not affect sound and/or integrity. 
Hopefully it solves your problem. 

I am the original creator of this thread.

Just so people are 100% clear on this issues... it is NOT software related in any way.  You can unplug the unit from the wall and wait days and it will still pop and snap.  No software update will ever fix this physical issue.

The sounds it makes is from the plastic expanding and contracting from either external temperatures or from when you use it and it warms up.

Again it is also worth mentioning that I started with MK1 with this issue. I then replaced it with TWO separate MK2 over the course of a couple years. No luck.

B&O support was totally useless every time I brought it up to them. They kept making stupid suggestions as "try a different Wifi channel" or "connect it with ethernet" even though I made it clear it was still popping when playing no music and its not even plugged into power.

B&0 actually took my unit twice for weeks and called me back "Its working perfectly with no problems" only to take it home and have it pop within minutes of coming back home.

Shame, such a nice product with one ridiculous hardware flaw. The saddest part is B&O still seems like they aren't even aware of it.

I hope loosening the screws helps though.

My B&O dealer suggested I return the unit so a technician could loosen the screws. I figured I could do that myself. So I did. And it worked…

Good Morning, 

just wondering if loosening your acres has still worked?

my unplugged 2016 A9 sounded like fireworks all night last night. Will have to give the screws ahi if you feel it worked?

Hi, 

I noticed your post is a few years old. I have the original A9 and the same loud issues. Have you found a solution? 
thanks in advance

I do get small pops from time to time but nothing like it was before. I'll probably loosen a few more screws when I feel like taking the cover off. Mine gets 2-5 hours of use daily.
