Vivid Audio Moya M1-World's first 8-woofer force -canceling speaker

[pablolie]

To get back on topic... the engineering and passion that goes into speakers like this is mind blowing. No holds barred stuff.

The question is... how practical is it (and it is a silly question because practicality is probably the last thing a prospective buyer of these has in mind)?

If you buy these, do you put them in a perfect large amphitheater that's optimally treated to hear them in a pure state? Or do you EQ them to tailor them to your room and potentially neuter the sound they were engineered to produce?

sure sure, but I said with HANDS ON experience not only theoretical. and also optics guys… I had experience with communicating with radar expert , I would say a pleasure. and it is also good to see from slightly different angle to make “view wider” because cylinder is neither a cirlce, elipse or rectangle, it is 3D all at once (neglected by some famous theories) various angles help to understand matter better, as I said theory plus practice is only way. and key is to avoid wishful thinking even for smartest guys, it hurts sometimes .

indeed it is hell of a technical job 200% that is why that incomparable marketing p me off so much. and lack of information too, these fairy tales of that measurements dont matter does not correlate well. Also guys who built bridges roads skyscrapers planes orbital stations do remarkable job, so to put in some guru position I dont know… maybe I am wrong.

I would listen them outside in open air. If room then first thing is big room, no close surfaces, but first of all no parallel walls. because of lack of measurements you cannot tell really how reflections will behave. what will be amount or absence of floor reflection. polar response gives possibility to think how to better position speakers in room knowing room problems. I can say that there is no point investing in any good speaker if room modal problems ruin all bass, midbass , high frequency reflections ruin stereo, many many problems. and there is a solution. for any speaker you buy start with room. if room is garbage so is sound, so what is the point of that?

see on web Don Keele documents about his experiments with line arrays, very good indication where and what to solve. he has old B&W classic there compared what happens in real room. It is all doable, in my DIY projects I do this, and it works. But there are ton of details else too. Materials is the biggest issue for smart guys without money. Good materials and magnetic, enclosure and else cost a ton because are not mass produced. can talk all day, then get something together then cry about mistakes normal process.

This is nice. I think those who specialize in radar systems and antenas-arrays, definitelly can give very valuable insights!

It definitely worked for the late-John Dunlavy. His background was antenna theory and he was hired by the U.S. Air Force to design antennas; what came from that was the first log-periodic antenna in 1952 and classified as "secret." He later designed the cavity-backed spiral antenna used by NASA for communications and telemetry in the Gemini rocket program. The cavity-backed spiral is an almost perfect analog of a speaker driver backed by an enclosure. He said that his knowledge in electromagnetic theory gave him a lot of insights that most speakers designers aren't aware of. The vertically symmetrical drivers used in his designs came from what he learned in antenna theory.

exactly! beautiful! thank you for science!!!
Don Keele is no exception here you can see background that he took navy research (at least official info, there are always tricks with information)

Actually people need to think a bit about how guys like Vivid, LAcoustics or whatever etc became gurus. In my humble opinion they do not respect people before them enough, from which industry beryllium or diamond composites come from ? who paid for initial research , is it not tax payers, normal ordinary people miners who sponsored pioneers with their lives. I mean these guys not only insult common sense but those who gave them all these possibilities. So this is the major reason for my not so sweet attitude of some kind of guru people.. so I try to pay respects always to people before me because without their discoveries there would be “lost generation”. So before putting someone in guru chair lets think a little. I am definitely , can not tell for others

We have wondered far enough off the path. If you wish to continue this side conversation please start a separate thread to do so.

Let’s get back on topic please. Thank you for your cooperation and understanding.

As a previous owner of G2 S2s and current owner of Spirits, I have to laugh at all the armchair engineer / a'philes' comments all while it's likely not one person on this thread has heard them.

From not active, to, it has a small tweeter, to, make it active, just wow. I'll say this - I could've bought many speakers instead of Vivids, yet I chose them as they were the most cohesive, most effortless and most realistic speaker I've heard within my budget. And they punch way above their expensive price point (yes, I've heard the usual competitors).

Perspective and experience, folks. ;-)

I don’t even know to whom you are condescending, but I can see you failed.

I posted this in another thread, but I thought it might be useful to open source some more ideas in a separate thread. “To be a genius is to be misunderstood. But to be misunderstood is not to be a genius”. - Neil DeGrasse Tyson ..nor is being hard to understand - me. Ad Vinum Audio is like...

[Brent71]

Anybody seen any measurements of these yet?

 

[Andreas007]

I really appreciate the R&D and all the effort going into this and I'm fascinated what can be done.
Visually it is a monstrosity. Reminds me of some Giger art. Well, if your home fits to this.

Let's not do that whole back and forth please.

I'm not sure Amir can lift them to the Klippel

Exactly my thoughts! Although not as disturbing as H.R. Giger's art, but still far from beautiful.

From a technical point of view, it is also limited by the fact that it is a passive loudspeaker (certainly due to the target group and the possibility of being able to sell additional equipment).

 

[Pearljam5000]

This color has the least Giger vibe lol

Accurate measurements were done for many years before the Klippel came out, no reason they can't be measured the same way now.

At Munich it was one of the busiest rooms so no nice seats to even remotely one could come to listen to them as in a nice quiet room from MLP.
Yes,their ugly up close (to my taste) but at this size it's hard to find nice ones so I (personally) can justify it.Built is impeccable though,it oozes quality.

Most importantly they can bang,seriously.It's not only their SPL,these things have big PA-like force but at depths no PA without a (non-pro)* sub can do.

*normal pro subs don't do 20's,they don't even do 30's.

 

[Pearljam5000]

For $465K I'd expect that and more lol

$465k is a nice figure to write off at the end of the year,if you know what I mean.
Being a speaker is just coincidental.

If Lego made speakers...

Stuff like this makes me realize big Genelecs are the best deal in high-end audio. Aesthetics don't actually matter to the ultra-rich, but it must look expensive...
