kef uni q This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you SoundStage! InSight — KEF and the Uni-Q (October 2015). Following along are instructions in the video below:
“Over 50 years. Kefir has been producing some of the world s finest loudspeakers. The the world has changed over these five decades but calf s approach remains consistent. I sitting in the museum amongst historic calf products.
It s a great representation of principle. Which raymond cook dreamt up before 1958. We all listen to music on one loudspeaker 58. Or the first commercial release of stereo.
One speaker would be as close technically to the other coming off the production line and that was very important because 1958 fundamentally changed. The way that we were being asked to listen to music a loudspeaker is at the end of the chain and all this great stuff. Which is going in the chain before it we have to be able to reproduce all those nuances. The technologies generally come a long way in five decades.
We all know that but that founding principle is still alive today..
Every single care product is acoustically designed here reference series and blade and nuan are made here in a really interesting bespoke boutique factory. We sell production here and each pair of cabinets is it individually built by our own skilled technicians each component is tested and pair matched before assembly after each cabinet is assembled then they re transferred up to the acoustic testing center. Where they re tested against the line standard. When i speak all frequencies come from one point.
I don t have to mouth one one little mouth for treble and one big mouth of bass. It kind of be weird unique you was first in the c35. Which was launched in 1988. The idea of unique u is to try and make two drivers look and behave like they re just one driver.
Covering the whole band from mid range right up to the top end. So. When you have a distinct tweeter and a separate mid range. The problem is that when you get to the point.
Where you have to handover from the mid range to the tweeter..
The directivity suddenly changes and you also have the problem that the source of the sound suddenly shifts from the mid range to the tweeter with the unique you you don t have those problems first of all by putting the tweeter in the center of the mid range mid range controls. The directivity and we carefully design the drivers so the directivity matches up and secondly they re physically in the same point in space with a separated tweeter and woofer a crossover you ve got two sources of radiation and sound waves can add up constructively but they can also add up destructively and interfere with each other so with a normal speaker you get a vertical directivity. Which becomes very irregular across over and you don t have that problem with the eunich you secondly. It s just a much more natural thing for the whole audio spectrum to come from a single point over the 20 years that we ve been refining the technology.
We ve been figuring out exactly how we have to design the tweeter and how we have to design. The woofer so that the two drivers work together in harmony and at this stage. We re really at a point. Where we ve eliminated.
Most of the disadvantages of unique you and those benefits of having the single source position and the consistent dispersion. They really come to the fore and they re very obvious in the performance our drivers. All have a tangerine waveguide on them that s something which we developed to improve the dispersion at the very top end. You ll also see that we ve paid a lot of attention to the surround on the mid range.
Because if you take a conventional half roll surround you get a lot of scattering of the tweeter..
We ve developed a technology called zed flex. Which you ll see throughout one of the important things about designing a unique you is to consider the shape of the mid range cone because unlike a normal mid range this affects the tweeter. A lot now we have quite an optimized structure. We very carefully match the shape of the tweeter dome to the shape of the small horn around the tweeter and then if you if you look carefully you ll see that the mid range cone follows that completely smoothly without any interruption.
We re trying to do is create a situation where the wave coming from the tweeter just smoothly flows down the the waveguide of the mid range. If you take a look at the our series. The reference and the blade unique use if you look at them from the front. They have the same cone size and that s intentional because we ve optimized the size of that cone to work with the tweeter to give the best possible directivity match.
But it means from the outside of the product. You can t really see the differences in the design. It s only when you look at the back. And you look at the motor system that you see now what makes a blade driver.
Better so with the r series..
We have a relatively simple ferrite magnet system. But then stepping up to the reference. We use a neodymium more powerful low distortion motor and then on to blade. We have again a more powerful neodymium magnet.
But this time with a much bigger 3 inch voice coil. So one of the reasons that we ve been able to make big steps forwards in the performance of the unique you it s because of our use of computer modeling. We can do abstract experiments on the computer that would be very difficult to do in real life. And it also allows us to try out a lot of different geometries.
We re at the point now where our software is powerful enough that we can do several virtual prototypes before we build the first one these days we expect the first prototype we build to perform exactly like that computer model. But since i ve been here the commitment and passion for the speaker s being built is second to none the guys are here because they like what they build and they care what they do when somebody buys a careful out speaker. They re buying 50 years of heritage 50. Years of experience extreme passion and attention to detail in premium acoustic product you ” .
