New mysterious Genelec monitors

[Axo1989]

Why is there a need for 3 woofers ?
Do they all play the same frequencies or are the bottom 2 more like subs ?
Also why ars the bottom 2 woofers opposing , is there any purpose to that?

Cardiod control uses additional woofers side and/or rear for cancellation of the front wave radiation (to the side/rear at the lowest frequencies). I expect the available modes are somewhat complex as they have their own crossover frequency range.

I’m not sure about headphones but any Atmos system will play those tracks.

How many people in the world have an Atmos speaker system? 20?

That is much more. As "inferior" as it is, soon, most soundbars will transfer to ATMOS (with up-firing ATMOS channels), and we will see a rising trend in spatial audio all-in-one smart speakers. Whether this provides the ATMOS experience at home as intended is highly debatable.. but this is commerce at best.

Apologies if this has been already posted - but here is the Genelec launch and overview video:

So, the answer to a request for research in support of a claim, is a personal sighted listening report?

ABX and not personal. Pro listeners easily pick up constant radiated phase despite head movement, when drivers are not displaced, and the listening distance is short. Several had the experience a few days ago during the AES convention at Aalto uni. I also played anechoic recordings of revolving loudspeakers, and then everybody can tell the difference.

Reminds me of the Quadraphonic headphones in the '70s.

I personally know four people who has, plus me, that is 25% of the world

Not to mention that you can view the equipment of members systems on their signatures...

The only difference with quadraphonic in the 70s is that today the giants and content providers push spatial audio forward. It isn't much the consumer wants; it's getting pushed through the consumer's throat. And that makes me believe that spatial audio will eventually be a new standard. Time will tell.

Such a branding exercise. I was looking at the new LG gram ultra slim. Oh yeah it has “atmos” speakers in it.

Aaah, great test
A way to actually 'hear' polars.

 

[fpitas]

I’m also staring to wonder for us 110v folks if we need 20A outlets to use this. Because 6000w x 2?

Or rather 3000w x 4. I realize it will never ever draw that from the wall because I have 2 x 1800w of Genelec amplification running on one 110v 15 amp circuit.

Still I doubt you can put all 4 of those amps on a 110v 15A line.

Also does anyone know what they mean by “sonic advisor” services?

If you play it full blast, yeah. Remember music has a substantial peak-to-average ratio.

Sonic advisor probably means they help set it up for you.

Makes sense. Whatever phase “distortions” exist in the recording is one thing. I feel like that’s fine.

I just don’t want to add any of my own if I can help it. Same concept behind treating your room. I don’t want to add anything from my room.

Yeah it’s very unlikely it will pull that kind of power from the wall. The peaks I believe are handled by capacitors.

Maybe if you played pink noise and fully cranked it up it may trip a circuit breaker.

It’s similar to what this guy does to demonstrate his point. Of course on an entirely different level. Starts at 1:30 about 10 seconds.

I wonder if you could hear what the Klippel mic picks up after it does the corrections. So as to avoid the need for an anechoic chamber.

I agree… but, there are situations where I actually prefer adding phase “distortions” e.g. upmixing stereo to multichannel in order to decorrelate the highly attenuated and delayed surrounds, and, when deliberately using left-right “phase shuffling” to improve the stereo phantom center effect in some certain stereo recordings and (mostly) MCH tracks when played back into traditional stereo pair of speakers in a very dry room.

Yep there’s a difference between what you choose to add and how you choose to add it vs what a loudspeaker feels like doing without your consent.


I just found this: https://studylib.net/doc/18510796/stereo-shuffling--new-approach-–-old-technique


Very complicated. What exactly does it do? Does it require additional speakers from the L+R or does simulate ambience from the L+R pair?

 

[dedobot]

Speaking of Atmos , I wonder how the stereo music sounds thru Atmos installation ?

I don’t think it upmixes at all. I may be wrong. The content has to be created in atmos and then it can be down mixed to stereo.

Easiest way to try is a pair of HomePods.

Strange thing is that the amps are electrically rated way lower:

The wait is over: Genelec 8381A point source main monitor has arrived

I'm sure they sound very good. Now, I read somewhere weight and measures: these monitors are gigantic: you have to explain to me where I should put them. I'd spend 70k to get this same performance, but loudspeakers have to be the size of a shoebox Very funny ;)

So capacitance takes care of the peaks?

 

[srrxr71]

Okay this makes sense. I forgot that S is the difference and M is the sum. So increase the S and you increase the perceived stereo width.
