I don't know if this official manual would be of any help:

I am not a Beolab 50 owner (and probably will never be) but I love reading manuals 😁

Hehe thanks! It’s a very good manual and I have it but the guide for how to unbox and assemble them properly, including setting them up.

All that is available in another guide that is only given to staff and I find that super weird. It’s like selling a car but not telling anyone how to drive it. 😁

When I had those problems, I contacted my dealer. He in turn contacted B&o. This is what we got in response:

 

Here is an answer:

 

1. Which driver is playing and how depends on different things like volume, frequency, latency mode and beam setting etc. Here is some technical explanation: 

In low latency mode, only tweeter, one midrange, front woofer is working + both rear woofers below 80 Hz.

In high latency mode, all drivers are working

In low latency, narrow mode, all drivers are working

however ..

- the amount that each driver working is different from mode to mode

- depending on the mode, different drivers will be working in different bandwidths - so (for example) if you play a sine wave at some frequency, one or more drivers will not do anything - but they will at a different frequency

- the relationship of signals from the drivers does not change with volume. They all go up and down together - even though they’re different from each other.

 

 

2. Distortion is not something we can figure out from logs, there might be a defective amp or speaker driver (likely on one of the speakers), it is possible to exactly determine this by test sound option within Service Tool.

Otherwise the issue might also be coming from the source or source material etc, the technician must be able to determine this on site.

This is the problem I hade.

 

Our customer called us today, and he have noticed that his BL 50 speakers playing vety low volume and that 3 out of the 7 drivers is playing in each speaker.  The tweeter works, the middle midrange and the front woofer is working, but not the side woofers and not the 2 other front midrange drivers, they are dead on both speakers. It is like the speakers is in limpmode in some way ?  The customer have try reset them , pull the mains for a couple of minutes but no luck.

And are they ok now? I do not think so even though they sound good.

Narrow in high latancy and wide in low.

When I play via analog RCA or spdif from bluesound node 2i, it's like this.

Narrow mode plays with all speakers.

Wide mode plays with everyone except the two lower middle registers.

When I play through powerlink with sound mode 2 or airport express high latancy through optical.

Narrow mode plays with everyone except the two lower middle registers.

Wide mode plays with all speakers.

It doesn't make any sence!

Nope, it’s hard to know what works and not. And B&O isn’t saying anything. So as a customer with 35 000 euro speakers in a bit confused but I’m trying to realize that we aren’t supposed to care :).

Mine sounds good sometimes, and sometimes not. It seems like they maybe fail to choose the right latency mode, or whatever. I can just speculate as I simply don’t know more than I hear.

As far as I know there isn’t even a recommended cable to use.

And a way to see that the amps is working, that should be a test feature available even in the web interface. There are so many amps inside so a simple way to check if they sound one by one, wouldn’t that be extremely helpful for everyone?

Having to send out a tech isn’t very environmentally friendly and it would save a lot of time to make that a possibility.

I think all programmers who work at bang & olufsen have alshaimers.

They sounds harsh played from bluesound node 2i with spdif supra cable. More detail and a lot more punch but much more harshly.

If you are going to insult people at least spell it correctly.

And btw, if one of your family members suffered from it like mine I am sure you would not find it funny.

Hi All, I started this forum post to solicit input from current Beolab 50 owners about how the speakers might work best (or not) in my particular setup.

I've gotten great insights both from current owners, as well as trusted and experienced employees of B&O, and it has helped me feel confident in moving forward with my investment. I'm appreciative of the advice, and I'm excited to add the 50s to my setup--and to my ever-growing collection of B&O equipment.

Everyone is entitled to their opinion, and I'm sorry to hear about some issues some folks here have with their speakers, but I'd appreciate it if complaints--and especially insults--were taken to another forum.
