What kind of preamp would you use to drive 4x BL5?

What I would like to know is if all this BL50 magic isn't 90% due to the room compensation feature.

If you run 4x BL5 from a Beosystem 4 you will have sound spread all over your room, in all directions as they are very wide. If you run the same setup from a preamp with Dirac Live, for example, the sound will be much more detailed.

I've tried this configuration in my 7.0 setup (1x BL10 4x BL5 and 2x BL8000) and the improvement was very impressive. Still I'd like to hear a pair of BL50 for comparinson.

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 ;-)

To see sharper I squint my eyes. I loose a bit of field of sight, but who cares for those sitting off sweet spot? A two part enclosure on the back of the acoustic lens moving a little bit around covering the front a little bit (and distorting the sound? -> bad idea).

Good analogy thereSmile - 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. 

My earlier postings regarding beam width and BL90 vs BL5 can be seen here: Peter Pans blog side s37

That would be 'Beam Direction', not 'Beam Width'.

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...😮
