anyone else spot the diagram on peter pans messaging pages ?
Yes, here is where it came from - thanks to kuyttendaele, who spottet that on his tv:

There is a tv - and there is a BV
I bid farewell to my final display pair of BeoLab 5 yesterday as they shipped to Guernsey - the new replacement is stunning in my opinion. Visually, Iove them - the times we sent Lab 5s out on home dem, and couldn't get them past the lady of the house, due to their 'appearance' , I firmly believe it won't be the case with the new speakers!
Sound quality, whilst always subjective, I think they are considerably better than Lab 5s, not far off Lab 90... can't wait to get the in the shop!
I don't think I have given anything away here, so hopefully won't get my knuckles rapped by big brother 😮
ahh ! thank you millemissen
I still don't think people have spotted the diagram...

KMA:Ah, more of the design given away BeoVision's speaker selection. Indeed, the line drawing in the dealer invitation earlier this year was BeoLab 50 as seen from the top. Interesting design – and a motorized acoustic lens on top would add a little B&O magic KMA B&O product history since 1991: Ridiculously long to list in a signature.
Hi all BeoWorld nerds - being new to Beoworld blogs I dare to give my thoughts on BL50. A speaker that might cause me to spent the money!
I am very impressed by the sound quality of BL90, especially image location and the low frequency ability without resonances. Huge improvements to BL5 based on the technologies "Beam Direction Control" (in full frequency range) and "Active Room Compensation". Looking into Geoff Martins blogs regarding technical background material is a pleasure for me. And all is summarised in the BL90 Technical Sound Guide (B&O homepage) also prepared be Geoff.
Now to my thoughts on BL50 looking at the new sketch posted by BeoGreg and Peter Pan together with the invitation posted by Lee in an earlier blog, I believe it is an almost triangle speaker looking from above with sub and midrange speakers in three directions giving a total of 6 speakers + acoustic lens. With that configuration B&O can implement narrow and wide Beam Directional Control in low and mid frequency range. The acoustic lens on BL5 is almost equal to wide mode on BL 90. So, wide mode would be easily implemented on BL50. However, narrow mode is essential regarding phantom image location as Geoff calls it, and how to implement narrow mode in BL50 with an acoustic lens? Some fancy mechanical solution perhaps?
Some comments Lee?

As mentioned on another thread. My speculative guess is that the BL50 is a 3.5-way loudspeaker array. Treble, Mid and Bass array in the main cabinet, standard monkey-coffin configuration. Pop-up acoustic lens - adds some B&O "magic" and is a cost-effective mechanism for wide/Omni dispersion.
The internal Mid/Bass are single array to save cost and there's a fine box of tricks with a plug-in microphone (a la 90) which can make the single Mid/Bass array perform to a reasonable extent in any room. I would envisage that this arrangement is not a dynamic as the BL90 - that has 3 times as much gear on-board than any other active loudspeaker to do the tricks it can.
I'm sure it will sound good regardless as the technology in DSP is SOTA and generations ahead of the BL5's they replace.
ps57: Some comments Lee? -ps
One comment. Yes.
"I signed an NDA..."
.
Present: BL90, Core, BL6000, CD7000, Beogram 7000, Essence Remote.
Past: BL1, BL2, BL8000, BS9000, BL5, BC2, BS5, BV5, BV4-50, Beosystem 3, BL3, DVD1, Beoremote 4, Moment.
The question is, what do they want to achieve with this speaker?
I am sure that it is not just a 'smaller BL90'.
It would have been easy (too easy, I'd say) just to scale down the BL90.
They want it to be something different, I am sure.
But we won't have to wait long anyway - it is rumoured that 'some' dealers (in DK, at least) will have them on display already end next week.
We'll see if that rumour is right???
Otherweise it is not long untill IFA2017.
By then we will learn about the 'philosophy' behind the BL50.
Those in knowing will give exact the same answer as 9 LEE, of course.
P.S. The acoustic lens is per definition supposed to give a wider dispersion - for one man AND his friends/family.
I don't think there is much to change there.
As for some 'fancy mechanical solution', I am not sure that is possible, because the Acoustic Lens Technology is licensed.
Highly interesting - sure there will be some magical math involved ;-)
Yes, of course LEE. And of course we will have to wait, but it is kind of fun just to guess.
If you have a look at Geoff Martin presenting BL90 in this video - Top three features, live - I believe it is obvious that beam width control is essential to obtain the very good image location that BL90 handles. (Maybe LEE participated in the presentation by Geoff?) Beam width control is really what is the differentiator for B&O in the high end market. Active room compensation is also important, but several other companies masters this technology.
If you look at another of Geoff Martins postings that explains beam with control (in lower frequencies) in detail, it requires at least 3 speakers in 3 directions! I would expect this to being part of BL50.

Well, if you wanted to 'narrow' an acoustic lens, which is a physical object, and you needed to be able to do this whilst the speaker is switched on, what would be the best way of doing it?
It's a pretty simple concept - almost like when you're shouting at someone in the distance and want your voice to carry straight froward. What do you do with your hands?

@9 LEE
exactly what I proposed, when that question was asked in the danish Peter Pan thread.
However, I am not sure, that tweaking the Acoustic Lens mecanically that way is allowed due to licencing of the technology behind the lens.
But, you never know, what the guys in Struer are able to - that is, you do know in this case ;-)
Good analogy there - with the hands narrowing the sound. Hope such kind of acoustic lens is implemented in BL50, it would be technical and visual superb. And only needing one speaker to implement narrow beam.
Regarding the importance om beam width control in lower frequencies I posted some figures from Geoff Martins blog B&O tech #48 on Peter Pans blog. Here the massiv improvement between BL 5 and BL90 can be seen. The control of the beam in low frequencies can only be obtained by speakers directed away from the front. So that is why - in my guessing - there are three speaker in a triangle in bas frequencies and in mid range.

I know…B&O virus has grown on me !
I receive my first pair of the new speakers next Tuesday... not sure I'm allowed to say that though - no doubt get another rebuke for mentioning it by the social media police at B&O...😮
Nice, and if I'm lucky I'll see and hear them tomorrow- that's very interesting
Millemissen:That would be 'Beam Direction', not 'Beam Width'. MM There is a tv - and there is a BV.
seethroughyou:I'd prefer a bit of extra length and width
My wife keeps telling me the same.
seethroughyou:Seriously, any more news???
No - I guess you'll have to wait untill end of week 32....
....unless you know where to look ;-)
Someone shared a picture on Facebook in a Danish Bang & Olufsen Group. Have the speakers been shippedd to dealers so it's possible to see there?

No responsible dealer will show them before week 32!
Beolab 50 -New is that the acoustic lens is adjustable, so the trebleCan be changed, what more earlier has also suggested.

Hiort:Just looked at the BL50s... They where not connected so I could not listen. They sure look like a pair of premium speakers. Lots of beautiful aluminum trims. The wood looks super. Standing alongside BL5s, the BL5s looked a bit tiny Can't wait to listen to them

Pictures or it didn't happen! (kidding!).

You'll love them. They're amazing.
I know it sounds crazy, but you'll think £25,000 is actually very fair value for money.
I'm very much looking forward to the reviews on here from BeoWorld Members who've had a listen.
leogoeswild:
The speakers look stunning! Thanks for posting! (Edit: I'm glad I got to see the pics before they were understandably taken down).
I'm assuming that's an 85" Avant based on the comments that they make the BL5's look small in comparison. These babies are quite substantial. I'm eager to read their specs, and of course, the magic of that acoustic lens.
From what I can surmise, it looks like the side flares of the lens can retract in and out to potentially make a narrow or wide aperture for sound dispersion. Intriguing!
