Ok, but does your audio gear have rotons (metamaterials)?


Not yet. But get ready for the LS50 Meta Meta.

"A group of researchers is working on metamaterials that "grow" rotons. Metamaterials exhibit optical, acoustic, electrical, or magnetic properties that are not found in nature.…Thus, it might be possible in the future to better manipulate sound waves in air or in materials, for example, to bounce them back, redirect them, or create echoes. These materials have not been demonstrated experimentally yet; however, it should be possible to produce them by using technologies such as ultra-precise 3D laser printing." https://www.sciencedaily.com/releases/2021/06/210610135559.htm

I had the Kef Ls 50’s Metas on loan from a friend and my 50th anniversaries and i would never spend 1300 to 1500 to replace 50th anniversary now with Dirac in the picture. Using an Arcam sa30 is a game changer and you can set different filters you can also do a sweet spot mode a focused mode or a wide mode or turn it off for all analog as my room was designed using Cardas ratio. To me they are both great values in audio probably one of the best besides my Hales T-8’s or my Sonus Faber Extremas. The most beautiful part about the metas is I just purchased a brand new pair of LS 50 black edition for 600 bucks brand new in the box. Going to use them downstairs using my old Rotel 1067 that’s had a recap it’s a monster which has a linear power supply big toroidal transformer. The beautiful thing about this whole situation is now a lot of people can afford a super class A speaker for less than half of what it cost originally. The black edition pair that I got I open the box myself and I paid the guy 600 bucks. It’s a win win. I will say the navy blue LS 50 meta with the champagne driver was so cool looking stunning but it was not worth $1000 more with dirac in the picture and even my schciitt audio Loki+ can help improve it but to me the old ones they don’t need anything with Dirac. And for 600 for a pair the brand new blacks editions with the flat black driver and metallic cabinet looks cool as hell. If you have the original LS 50’s no need to upgrade. Not enough their. Just my humble opinion. Spend 1500 on records/cd,s or Audirvana or a Schiit Frey+/ Vidar or a Gungnir dac or even a new Schiit biforst 2 for a killer bedroom system. Goood job kef good job
PS also if you notice most companies say we reserve the right to improve our product without any notice after listening to my blacks they sound a little bit tighter in the bass than my original 50th anniversary which makes them play lower and louder and clearer. Yes I heard this  difference. Also from an audio designer friend of mine who said Kef made changes in later productions of the LS 50’s and I hear it. It shows also name with held to protect the innocent. Enjoy both speakers they are fabulous transducers and a bargain in audio. If you would had said 20 years ago I would be would be able to buy a speaker with this kind of sound quality for this kind of money I would have laughed you out of the room. 🤘🤘🤘
I haven't been about of recent, so am in no fashion offended by anything proffered.....

     I have culturally cancelled my own capriciously callous (Whale of a fail) attempt at comedy, having clearly offended the congregation.

      Probably having removed any doubt, as to whether needing Mental-Metamucil was a joke, in the process!
@thecarpathian- "I personally have not jumped, but it is indeed something I am quite interested in doing."

     DONT pass up the opportunity!   It’ll be the most fun you’ve ever had, with your clothes on (even if you only do a Tandem).
@avsjerrry- "Well, all that can happen here is to crash the ’puter....on a physical level of sorts, anyway."

I meant to mention, having tossed one of my laptops at the wall and putting my fist through another’s screen, when trying to get acquainted with a keyboard (again) and so forth, very early on, in the technology.

Would either of those count as a, "crash"?

Been waiting for an efficacious, Mental-Metamucil product, with which to clear my head.

Tried working things out with a pencil, in the ear, up the nose, etc, but, thus far: no movements of merit, worth mentioning!

I use natural rotons that spin in a positive direction and filter out all those unnatural rotons that spin in the left direction.  The left-spinning rotons are almost in the same category as bad electrons.  All it takes is a special cryogenically treated power cable and a pair of frumeral steam regulators with dark energy suppression. 

If the frumeral steam regulators start to get jammed on peak musical output, they can be cleaned using dark energy that repels rotons.  It's just that dark energy is repulsive and must not be allowed in the audio signal path.  So it must be suppressed.  

I actually have three brand new power cables with frumeral steam regulators.  They were $26,000 each new, but I'll part with them for a measly $18,000.  Dark energy suppression can be added for only $7,000 per power cable.  Cash sales only. 

Dark energy is available from the Quantum Physics Department at the accelerator in Cern, Switzerland. I got free samples but it lasts a really long time.   
I personally have not jumped, but it is indeed something I am quite interested in doing.
Have several friends who have jumped.
And miller, I am on occasion certainly guilty of that!
@thecarpathian-   That was hilarious!

       But: Blood Moons scare me, even with BOTH eyes wide shut!

                                Do you really jump?
That’s nothing!
You should try a night dive during a full lunar cyclops....
(must be done with one eye shut)
@thecarpathian- "Interesting tidbit, when you finish a sentence with three periods instead of the standard single period, that triple period is known as an ellipsis..."

     HEY: I made one of my favorite skydives (perhaps: THE favorite), during the 2017 solar ellipsis...!

     Flew between two huge clouds, for 5000’ and set the record for off-DZ landings, too (9.5 Miles).   GoPro video available, on request.

                                          (while we’re being punny and off topic)
Sound is an experience, like color. If a speaker falls it will vibrate the air, but with no one there to hear it there will be no sound. Just as there is no color without an eye to see it there is no sound without an ear to hear it.

Hello,
If a speaker falls in a forest with no one in the forest, does it make a sound?
🤔
If it’s anything like light, only half of the time. 
Thanks, tomic60.  I've been looking for a way to 'weld' my Ti cones instead of VHB dbl face film xfer tape.

Now all I have to either procure or DIY a electron beam welder about the size of a soldering gun...('Dramady effect' *L*)

Alternate application:  On the Highway Of Others' Hell.

I can't wait for the reviewers' takes on the tech. .. ... (*delayed, w/echo*) *g*
Soviets used to make submarine hulls out of titanium.
Must have been quite challenging...(note the fancy ellipsis for dramatic effect)
Try squeeze casting Ti and then electron beam welding it into ….. important bits for the F-22.

maybe we should’ve used rotors….
Ah, that variation of the NBW; Nut Behind Wheel.....

Well, all that can happen here is to crash the 'puter....on a physical level of sorts, anyway.  Software, reboot.....

MetaMentalMisfortune, rubber mallet....;)
@asctim-    Ti is also very difficult to machine, must be machined slowly, requires special/expensive tooling and wears that tooling, very quickly.  
 
                   Great stuff, when you can use it!
@tomic601 -    "I also believe my point about “ large “ was also made in Animal House. Veggie aisle, … say no more…."

                                                                    FIGURES!




@avsjerry-     "...happy you're happy with 'Enter'...;)  But many problems stem from PEBKAC....*G*."
   
            In my case: it's NLBK (Nut Loose Behind Keyboard)!
@asctim....HO, I think it'll be while before Active Roton Dispersion Arrays for audiophile purposes may be available.  And I'd wager that speaker tech might have to respond in some fashion to make it a real thing...

...an acoustic hologram of sorts, without bathing in lasers....  "Nice, but gives me a sunburn of sorts....OMFG, my ears have burnt off ! ? !"

Ti is nice, but yes, pricey.  There may be a lot of it, but its' nature makes it hard to process anything out of it for use on or in anything.  I have 2mm sheet that one can cut with scissors, but has an edge like a razor blade....  Folds crisp, but one shot is all you get at it.
Very interesting. I'd never heard of a roton. It'll be interesting to see what can be done with these through engineering.  When I was in high school the hope was for room temperature superconductors to change everything. Didn't happen but superconductors do have their uses. The other big hope was cheap, abundant titanium to replace much of the items that are now made out of steel. Titanium bikes are here. They're very nice but expensive. Not too many car chassis made out of titanium that I know of. Ti is abundant in the earth's crust but remains hard to work with. 
..also referenced as a 'suspension point', an inference that there's a previous line of thought....
Typically 'derailed' (sometimes deranged, depending of POV....) or drifted on from....

I've stood accused of many things; OCD, ADHD, DWI, DWJust Fine, Thx, others...

I'll abstain from '... - - - ...', but Morsely it draws attention not required. :)

Next?

Micromegas! Love that. Surely a riff on something more ancient. The monads of Leibniz? The dead atoms of Lucretius? 

Ok, that's enough of that. Back to the main discussion...about...the RETURN key. [Anyone up for a debate on the Oxford comma, instead?]
Like I've said before, that scene in Animal House is riffing on Voltaire's Micromegas.
@asvjerry ,
Not meaning to pry, but do you ever get the overwhelming desire to roll around in the mud?
I also believe my point about “ large “ was also made in Animal House. Veggie aisle, … say no more….
Nobody marketing to men, with possible exception of Lyle Lovett use the term “ Large “…

I rest my mega meta case
@rodman99999 ....happy you're happy with 'Enter'...;)  But many problems stem from PEBKAC....*G*

@millercarbon-  " By return I meant enter. Whatever they call it on your keyboard that takes you back to the beginning of the next line. Only necessary on certain browsers or computers or whatever that this site doesn’t play nice with."  

     I find it interesting, on this rig: it doesn't matter whether I hit the spacebar (4X), or four periods and the Enter key once, it still Returns for me.     Not knowing Enter = Return (and trying to form paragraphs, on this site) was giving me fits.
     Thanks for helping me learn that trick!    Just wish I'd known it, before typing that (felt like so sloppy) dissertation, above.
@hilde45-    Animal House is one of the funniest movies ever.   A classic I have to watch, maybe every six months.  
     Ever feel like you've known everyone in the flick, personally?
@tomic601 -     I really like the way you did your moniker!   

     "IF i squint, it looks like the giant hadron collider…. "    

      Not a big thing, but, I like to get details/names right/correctly and believe you might as well, so:   the proper name is, 'Large Hadron Collider'.   

        "thank god i work with ex Dwave and Cray dudes, they can help me create the bubble….wait for it…..with software….."    

      All the bubbles I'll EVER need, are already in my head!



   
     
    

       


@rodman99999 No worries -- Best Thread Hijack Ever! I didn't have anything to add just thought that the materials science aspect of rotons (assuming they're a real thing and we figure out what to make with them) might spark some thoughts. 

Glad to see people are having fun with this. For some reason the go-anywhere nature of this discussion reminds me of the scene in Animal House with Donald Sutherland and the student, hanging out:
 
Student: That means that one tiny atom in my fingernail could be. . .one little tiny universe....Could l buy some pot from you?"
I mean this in all sincerety, there are many on this thread who are truly erudite in matters of physics and it's practioners. I also now have some understanding of the the concept of "meta". 
But having a background in marketing and advertising, I presume in the concept of KEF's new LS50 variant, "Meta" means new colors for the enclosure and driver(s) and a fiddled with crossover.
"Rodman, do NOT believe everything you see on the net."
How are we supposed to believe you, you posted this on the net.
@asvjerry -  " ...but not surprised, tho.... We be Borg soon enough...."  

       Check this out: http://human20.com/tag/nanotechnology/   

     After clicking on the, "read more" link, be certain to go, "back" and scroll down to the second part of the article (Timeline To Immortality).
@clearthinker-   "Rodman, do NOT believe everything you see on the net. As time passes, more and more material is false, sometimes through ignorance, more often through intent to put up false and misleading information."  

     What you, CLEARLY refuse to face, is the fact that everything I posted, has categorically been proven/confirmed, through scientific research and experimentation/testing.  Oh: and most of it, WAY before the Net ever existed.  

                        Something commonly referred to as, "HISTORY".  


      ps: If you're going my make comments regarding a scientific subject: it would behoove you to learn a thing or two (at least) about it, first.      Higher education is your friend!
"I believe for the Rotonic Pulse Generator to have an efficacious effect in the Southern Hemisphere, one need simply to flip it upside down."   
    
     Hadn't thought of that!     Pass it on to Ted (apparently: he hasn't yet, either and might miss that market).    

"Also, the technically correct way to say that expression is ’champing’ at the bit."
   
     Funny thing: when I type no more than, "chompin" in my search bar, it automatically fills in a series of ways to say, "at the bit".      Guess I'm not the only one that makes that mistake.
