Bang & Olufsen Beolab 90

[m1ts0s]

The striking design is built from more than 65kg of aluminium and promises to be the "most complete and powerful digital loudspeaker" ever built for the home.

Bang & Olufsen doesn't tend to to things by halves, so it's no surprise the company's 90th anniversary is being recorded with a mind-bogglingly different piece of speaker design.

The BeoLab 90, which is due on sale on the 90th anniversary date, 17th November, and will cost "£26,995 per unit", is claimed to be B&O's most complete speaker to date and certainly cuts an eye-catching figure.

B&O's 90th anniversary speaker has "no apparent visual front" thanks to its angular design, with speaker drivers placed in various directions to help guide the sound around a room.

Boasting a 360-degree design, the BeoLab 90 aims to deliver the ultimate sound experience whatever your room, whatever you're listening to and no matter how many people in the room.

The new Active Room Compensation takes care of the first bit, calibrating the sound of the speaker according to the size and shape of your room, the furnishings and your listening position.

"You do not have to be close to the speaker or even in front of it to get an excellent sound experience," says Bang & Olufsen CEO, Tue Mantoni.

It's not all about creating the ultimate sweetspot for set listening positions, however. Beam Width Controlallows you to "change the width of the sound", should you have a room full of people or just the family together to watch a film.

As well as more than 65kg of aluminium, there are black fabric covers which B&O says "hover like sails in front of the speakers", plus a curved wooden base.


"BeoLab 90 is our most complete loudspeaker to date. It is a committed investment in excellent craftsmanship, ideal materials and superior technology. Future Bang & Olufsen products will benefit from the innovation and know-how gained from the development of BeoLab 90 – and our customers will savour in perfect sound from the ultimate loudspeaker for their home," according to Mantini.

BeoLab 90 has 18 state-of-the-art Scan-Speak loudspeaker drivers placed in carefully defined locations and directions to deliver maximum performance in frequency, time and space. The loudspeaker packs a combination of 14 channels of the latest generation ICEpower amplifiers - a compact and highly efficient platform developed by Bang & Olufsen - and four additional class D amplifiers - all customized for BeoLab 90s specific requirements. In total, the amplifiers can deliver up to 8200 watts per loudspeaker.

Εντυπωσιακή υλοποίηση!

 

[AriPetro]

Πολυ άσχημο βρε παιδί μου, σαν όρθια κάμπια δεν είναι;
Την B&O τη θαυμάζω τόσο για το R&D και τον ήχο της (ιδίως από τις πρόσφατες υλοποιήσεις της) όσο και για το εξαιρετικά όμορφο design των προϊόντων της.
Ιδίως το όμορφο design είναι στο DNA αυτής της εταιρείας, εδώ φαίνεται πως πήγε περίπατο...

 

[wizzy]

Εμένα, από την άλλη, μου άρεσε πολύ το look του συγκεκριμένου ηχείου! (ΟΚ, περί ορέξεως, κολοκυθόπιτα)

Το θεωρώ εντελώς αντισυμβατική υλοποίηση (από πλευράς σχήματος/design) και θα ήταν πρόκληση για τον οποιονδήποτε να τα ενσωματώσει στο χώρο του - είτε dedicated είτε "οικιακό".

 

[Zizik]

Βγάζεις τα πανιά και γίνεται utilitarian κουκλί.

 

[brego]

Βασικά ξεφεύγει απο τις κλασικές υλοποιήσεις που έχει μάθει το μάτι μας.....
Προσωπικά μου αρέσουν πολύ αλλά απο πίτα που δεν φας τι σε νοιάζει κι αν καεί.

......τα τόσα τουίτερ με προβληματίζουν........

Τέλειο το βίντεο παρεπιπτόντως.

B&O Tech: Shark Fins and the birth of Beam Width Control

So, the question to answer was:

“Which sounds better:

a loudspeaker tuned to be flat on-axis, but with no correction for its power response
a loudspeaker that was tuned to have a smooth power response (in other words, with a “bump” around the crossover)
a loudspeaker that was tuned to be flat on-axis and had a power response correction provided by the dipole
?”

...........

The end result was a bunch of different conclusions:

The three different configurations of the loudspeaker (listed above) sounded different. (this was not a big surprise)
A two-way loudspeaker tuned to have a smooth power response and a loudspeaker with a flat on-axis response with a shark fin smoothing the power response sounded different – but mostly spatially.
Switching between those two loudspeaker configurations listed in Point #2 basically meant that we were switching between two different loudspeakers with the same power response, but different directivities (a fancy word meaning “directional behaviours”).
The dipole loudspeaker’s output was audible at the listening position because of the sidewall reflections in the case where the dipole was on top.
Switching the dipole on and off had a noticeable effect on the phantom image distance and width… When the dipole was turned on, the sidewall reflections were obviously louder, and the phantom images moved to a distance from the listening position roughly the same as the distance to the loudspeakers themselves. At the same time, the phantom image width increased and became “cloudy” or “fuzzy” and less precise.

All of those little conclusions could be folded into two big ones:

The original idea of using a dipole to fill in the power response of the loudspeaker doesn’t work well enough in all situations because we don’t know where the reflective surfaces around the loudspeaker will be in any given configuration.
Being able to control the directivity of the loudspeaker (specifically, how much energy is coming from the sidewall reflections) is a very interesting control parameter that we should look into…

So, this is where the concept of the shark fin died, but where the idea of “Beam Width Control” began.

Well… more accurately: it was the beginning of our thinking that being able to change the beam width (or the “directivity”, if you’re a geek) of the loudspeaker would be a useful “handle” in the hands of our customers. The idea that was born was something along the lines of the following: “If a customer could change the beam width of a loudspeaker, then (s)he could change it from being a narrow-directivity loudspeaker for people with one chair and no friends to a wide-directivity loudspeaker for people with a sofa and some friends to an omni-directivity loudspeaker for people throwing a party – all just by the flick of a switch…”

A series of articles about the technology behind Bang & Olufsen loudspeakers

"Originally from Newfoundland, Canada, Dr. Geoff Martin has degrees in music performance, sound recording and acoustics simulation. He has taught electronics and electroacoustic music composition at McGill University and the University of Ottawa. He is presently working in research and development in acoustics and auditory perception at Bang & Olufsen a/s in Denmark. Geoff was the Papers Chair for the 24th International Conference of the Audio Engineering Society (AES) on Multichannel Audio held at The Banff Centre in Canada. He is also the chair of the AES Conference Policy Committee and is a member of the review board for the society's Journal. In addition, Geoff is the author of a textbook on sound recording which is available at www.tonmeister.ca."
