Just a side note to the last comment from Geoff.
This goes for the BSys4-based BV's.
For the previous BV's it might be different, I guess (?)
Important - because a lot BL2 and BL9 owners have these connected to a BV7.

oops. Thanks MM!

Thanks for the answers Geoff!
WISA:
Very interesting to hear some details about how it works and that it will drop "frames" in the audio if there is signal disturbances. I think for now that cables is the way to go for me. WISA adds some power on latency I believe and while it will work, the TV and speakers will have to do more processing than necessary if I could just as well use my PL cables.
BUZZ:
I have Mk3 cables but I find the noise from the tweeter quite audible. It's the same from both but one of them is having new electronics fitted (and already had its tweeter replaced twice because of wrong diagnosis by the tech - it goes into thermal protection when I change sources after half an hour or so and the other speaker does not, very strange issue.) Will look and see if the new boards make any difference, but I think no. The source is Avant 55 and I am using regular Mk3 cables with short PL-RJ45 adaptors. I first had RJ45->DIN cables for BL5 but they buzzed even more I believe.
BL9 inside pictures where from this page:
I wouldn't be so sure the BL5 sounds a s good as BL19&BL18 actually. More sophisticated DSPs and modern technology makes a lot of difference. Geoff wasn't involved in the BL5 either, and he seems to have a better idea of what the speakers should sound like

Updates in electronics will only get you so far. Given that the the BL5s have 15" woofers with 1000 watts each vs. the BL19 which has (2) 8" woofers with (2) 160 watt amplifiers, it's not going to be a contest in the low bass department, alone.

I never said that either, but being able to shape the signal to the speakers design in an optimal way is probably easier than before and might give the speakers a better sound profile than before. Of course BL5 is stronger.

If you have a B&O Wireless Power Link (WiSA) transmitter, then the extra latency incurred by the WiSA Tx/Rx is accounted for. No need to worry about this.
Subwoofers:
Ah, great to know. I thought it was somewhat like that.
Interesting to see that neither BL9 or BL20 will remove bass from each other either.
But that BL5 would remove bass from BL2 and BL9 but not BL20.
Would this mean that I would get bass both to BL9 and BL2 if I would add one to my setup? For example I might find it useful because:
1) I never owned one - and that would be fun in its own
2) More bass when only using the built in speakers of the Avant
3) If I would like to replace the BL9´s with smaller speakers.
The automatic decisions made by the Avant / BV11 / V1 regarding whether or not to re-direct the bass is entirely dependent on the particular constellation of loudspeakers in a given Speaker Group.
However, if you don't like the automatic decision made by the TV, you can always override it in the Advanced Settings menu. For example, you can just set the Bass Redirection Level to 0 dB for everything - and bass comes from everywhere... I'm not saying that this is a good idea - but you might. :-)
I have many other questions but I'lll stop here, for now :P
Yes I also think that improvements have been made in the dsp field. But it is almost like saying that beoplay a1 can match bl18 because its developed later. You can not forget that using small speakers in the bass area will result in higer distortion. The bl5 only have 0,89% distortion playing 40hz in 90db verry low that is.

....and very loud that is.
Especially in a smallish room and for longer time.
Comparing the BL5 and the A1 is not fair at all - simply two breeds...for totally different purposes.

Thanks Geoff for your detailed answers and explanations. However I am a bit surprised that Bit errors turns stuff into danish but thats an entirely different thing 🙂.
I'll think about my future questions and ask them when I know what to ask! I still haven't been to B&O in Struer but I have been thinking about going for years. Would be fun to discus the sounds and technology in person as well, if you are available for the factory tours.
Very interesting thread. I just read through it for the first time. I was just about ready to order a pair of 20s to replace my 9s. Reading this makes me think I should listen the the 18-19 combination as well. I think I would like the way the 18s look more than the 20s. But unfortunately I don't think I will have a chance to make the three hour drive to my dealer before the June 1 price increase dealer told me about.
I had a pair of 5s in my house for a demo a few years ago. I had them for several days. In my room, probably due to the close placement to the wall, and one in a corner, they did not sound better to me than my 9s. Wish I had a closer dealer so I could do an in home demo of both 20s and 18s-19.
