BeoLab 90 background on room compensation and more

Why the BeoLab 90 loudspeaker? - Tonmeister at Bang & Olufsen explains the "Active Room Compensation", "Beam Width Control" and "Beam Direction Control"

[@charlesmaluleka8279]

The problem with those who are criticizing the presentation is the lack of understanding of how these speakers work and the technology behind achieving all that, these are phenomenal speakers. The performance is unparalleled and this man did a fantastic job.

[@-triumphgt667]

I think he is brilliant - he explains complex ideas so that those with little knowledge can understand. And having had the pleasure of listening to him in person, he is amusing and personable. I valued the time he took to talk to a friend and I when we visited Struer 10 years ago - was supposed to be going back this year but Covid spoiled that.

not a bad presentation very well vetted and defined and explained would've been fun to have been there. I'm sure there are very dense people not entertained or educated by any of this but I'm not really concerned other than pity. very well refined presentation. I like it so much I was captivated despite the imperfect videography.

[@daveanthonylucas]

Interesting video. Explains the tech well.

[@efviasnh]

Cool!

[@chetanramesh951]

Amazing!

[@ntokozonkala4730]

Wow.well explained.

[@draloha296]

We want to hear it 😂

[@johnsmith-zv1lo]

70-80k us dollars.... wtf

[@bernhardhnida3038]

starts with nonsesne. "want no bounce back from side walls". in real it is you want controlled reflections.

[@dkjess]

Presentation is interesting. But the recording is just awful. Way too dark, zoomy and bad sounding.

[@LokaLikesAsia]

TURN OFF THE SOUND OF YOUR GOD DAMN PHONE !

[@dhruvgrg]

An actual demo would have been nicer

[@jksala2864]

+dhruvgrg "An actual demo" is nothing you get on youtube....you have to sit in the same room as the speaker. I have heard them and they are beyond stunning. No words can describe them...

[@dhruvgrg]

+JKS Ala don't disagree with you. I'm familiar with B&O and do think these will be outstanding.

[@konstantinost3185]

Makes too many flawed assumptions for the sake of the" Demonstration", for instance, 2:35 The way human brain compares so we can understand when a sound source is moving away (or moving closer) is mainly because of the Doppler Effect not because of Reflections, we wouldn't be able to tell if we were in open space with no reflections otherwise. 9:50 Also false, as he correctly says low frequencies are Omni-directional, so you can't use the "back woofer" at 180 degrees opposite to the front woofer to kill frequencies "that way", you will "kill" frequencies ALL OVER THE ROOM.

[@Max-gc3bp]

Look it up on google, we do perceive depth in sound from difference in volume between sound coming from reflections off the wall and sound coming directly from the source not the Doppler effect. An example where you experience this is the fact you can tell how far away someone is much more easily in a room rather than outside on a field.

[@Max-gc3bp]

Btw there are 4 woofers at 45 degree angles to each other. Geoff Martin just said the back woofer as an example to make it easier to understand

Bad presantation/salesman :(

+M van Drunen This is the "inventor/brain/ears" behind the speaker, and i think the talk about the speaker are quite good from a technical perspective, often technical people lack people skills and have trouble communicate to others, but this is not the case here, i find the video interesting, and maybe the presentation would have been better if we were there live on the day, this is just a glimpse of the event. :)

[@Mortison77577]

+M van Drunen He's a hell of a lot better than the average engineering geek.

[@nathanchatelier8253]

+M van Drunen this is one of the better audio presentations I've seen.

[@jksala2864]

+M van Drunen He is not a salesman and has no training as such...he is the man behind the sound (Geoff Martin tonmeister at Bang and Olufsen)

[@fgroen1225]

+M van Drunen He's not a salesman but clearly a developer/designer, hence he knows what he's talking about. I find this presentation way more interesting than the waffle of a sales person who could just as well be selling a washing machine.

[@Mario_Terzi]

the worst speakers i've heard

[@PlatinumEagleStudios]

Meh I don't need this. My Bose 301's are just as accurate sounding. Bose is known for good sound and my 301's deliver it

[@YPO6]

+EpicEverythingDude75 I blindly believe you, and I think we have all necessary technology right now, no need to invent stuff anymore.

[@PlatinumEagleStudios]

YPO6 Bose will always be number 1 in my books

[@paveldvorak5512]

But Bose doesn't have any swag bass, style like my Dr Dre headphones and speakers man. It's gangsta science that makes the audiophile industry go round. Keep your fancy schmanzy graphs to yourself music is about da bass son.

[@robertradu4774]

LOL !!! Bose ?! Comparing Diamonds to Zirconium, I see ! You are a real conaisseur I see 😂🤣 You probably drive a Cadillac and think it's a Rolls

[@taatsiaqchemnitz3341]

You are so right. Like a Toyota is a Ferrari.

[@dennisgonzalez3576]

I'm sure the speakers are great. But that man is a horrible presenter. Not likable. Probably why his set of speakers are only set to sweet spot.

[@YPO6]

+Dennis Gonzalez He is way way wayyyyy better than someone who is worse than him.

[@paveldvorak5512]

How is he horrible? He actually explains the product in an entertaining way. Maybe you don't like technical explanations.

[@shiningdawn8578]

What an awful comment to leave. What is wrong with you?
