KEF's new Metamaterial Absorption Technology

[Mnyb]

Cool , would be interesting if this uni-q development eventually showed up in the R series to

For some reason I believe coaxial belongs in 3 way’s .

Wonder if they ever considered an active R series speaker ?

 

[Trouble Maker]

OMG is that an hdmi ARC port on the back of the new LS50W ?
Take my money

If it can work in a HT type of situation, some kind of HT bypass or CEC to play well with AVRs ...

I have the LS50Ws now. I'm trying to figure out how to use these things in a HT w/AVR I feel like the main character in a Daren Aronofsky movie.

The white and blue are my favorite, but there isn’t a single ugly colorway (even the gamer-y red/black is fine and I hate that color combo). KEF sure knows how to make good looking speakers.

That blue is sexy AF.

I’ll wait until the absorber works down to the woofer, ie MF-LF where most needed the technology.

I am afraid that an equivalent tubes labyrinth for LF would be too large for most loudspeakers but maybe at least for MF.

600Hz is already quite surprising low imo.

EDIT: to be clear though, AFAIK it only works for the tweeter. Just think it's interesting that it's effective that low even if there's not that much tweeter energy yet. I just wonder what they will do on future high end models. They might be able to get a woofer-sized metamaterial working for a new reference series

Somebody has to send the new LS50 Meta to @amirm

They are finally understanding that people want matte finishes and not unsightly shiny glossy things in their living space

The wireless too, so we can see how good the DSP is or how it compares to other solutions.

The white paper talks about both axial and radial metamaterials. A metamaterial approach in the Vivid/B&W rear tube form factor could push bandwidth down.

Because nothing sells speakers faster than seeing men crowded round taking turns touching and pressing the speaker cone....

I wish I could agree with you. There isn't one color that I could get into my house. Bummer. The contrasting drivers just don't work for my spouse.

I have a strong distaste for "coloured" products, especially when it comes to electronics and expensive/functional items. I don't think i've willingly brought anything that wasn't a neutral colour like grey or black, and maybe white or brown etc. if I didn't have to. If it wasn't for some of my wooden furniture my living space would look like a prison. But I must admit, the blue/gold one is gorgeous

I actually like some of the colors -- I like the blue too. I just wish they would offer one "boring" color (all black?) for those with decors that don't handle two-tone colors like these.

Their KEF Control & Stream apps are a mess. I never understood why they decided to publish 2 different apps the control the same speaker anyway. I hope they take a look at it while they are releasing the new wireless version.

As per the Darko review (preview ?), the app has been merged into a single one.
