Wolf von langa loudspeakers sound
The silence of winter was finally over on the first weekend of February. Off to Hamburg for the Norddeutsche HiFi-Tage - already the 15th of its kind and always pretty unique. Plenty of hi-fi knick-knacks and gadgets. We enjoyed it very much.

Wolf von Langa SON
It doesn t make a lot of difference whether I experience it live or from a packaged medium. A particularly memorable experience from my school days may illustrate this. In the tenth grade, six weeks before graduation, I was in a virtually hopeless situation.
With six unsatisfactory marks I would ve probably been held back, remain in the same grade, and not receive my certification. But then the Kinks fantastic Rockpalast concert saved me. If the old buggers can put on such an awesome show, so can I. The Kinks music and their energy actually gave me the strength for my transformation. Even though I am older now than the oldest member of the Kinks at that time, this hasn t changed the influence of music on my life in the least.
These pleasant experiences occur entirely on the emotional level. I don t even attempt to put them into the realm of the intellect. When I now write about music reproduction equipment, of course, the really extraordinary doesn t happen every time. With Wolf von Langa loudspeakers, however, these connections have actually been re-established.
He delivered the speakers to me personally, set them up, and carried out a function test. For better decoupling from the wood floor, I used the Plexiglas bases which were supplied.
Instead of my push-pull amplifier, I connected his single-ended B power amplifier. This version of the famous Sun Audio B has been precisely optimized by von Langa, with selected components and a vacuum tube assembly different from what is found on other versions of this amplifier, and as good as the others are, and based on my experience, this is certainly one exceptional amplifier, unrivalled among its peers.
It is both quiet and capable of reproducing musical nuances, color, dynamics, and finely structured loud music. Alone, this amplifier deserves to have its own story. I know Yupanqui s music inside and out.
But the feelings that were triggered by his warm, gnarled voice, and the rhythmically unusual. I got the impression that the old man was sitting directly in front of me in the room. He sang to me, and it seemed as if I should understand his Spanish, although I don t speak Spanish.
I got goose bumps, and at the same time and for the first time became consciously and unequivocally aware that Yupanqui s guitar was wound with nylon strings. Their buzzing and pulsating were very clearly audible. But this didn t distract me from the music; it pulled me deeper into it. So natural, so immediate and believable. How did this happen? What s going on? Is it just possible that you can build a better loudspeaker with field coil drivers?
Wolf von Langa is the son of an engineer, who began building loudspeakers in his youth. An early pair of his loudspeakers as the only designation they had at the time even landed with a well-known local dealer, where they were presented as a reference.
The dealer eventually returned the loudspeakers to the 16 year old von Langa, because nameless creations do not sell. Some detours and decades later with the enjoyment of music, its reproduction, and loudspeakers remaining alive this sympathetic Franconian decided to indulge his passion, and to bring his own driver designs to market.
For seven years he conducted extensive materials and foundational research; and finally and beginning in Wolf von Langa drivers and loudspeaker systems have been for sale ever since. Peter Walker with his Quad ESL57, and a prototypical baffle design for wide bandwidth developed in Japan, both achieved similarly coherent performance, as confirmed in measurements.
Foam pads perform the same function for the mid-hf driver. Compression driver and horn, the 38 cm bass driver, and the passive crossover with customization options Left side: clockwise from bottom left. The compression driver for mid and high frequencies, with a short cast aluminum horn.
Overwhelmingly massive at a weight of 15kg, mainly due to the use of a substantial amount of pure iron for the rear pot assembly. The CD constant directivity horn exhibits minimal beaming, and can effectively be fine-tuned with foam. The bass driver s rear pot assembly is made of one large piece of pure iron. A pocket is milled to accommodate the finely adjusted field coil with its flat aluminum ribbon windings and pure iron core. Additionally in its production the pure iron is degassed in a vacuum, thereby increasing its conductivity and reducing the internal resistance to the micro-ohm range.
The moving mass of a paper cone and voice coil assembly is a very light 43 grams, for a 38 cm speaker frame. The mid-hf driver is a 1.
The cast aluminum constant directivity CD horn, which was an Electro Voice invention from , exhibits very minimal beaming. The baffles themselves are made of plywood, then doubled in thickness with a layer of high density fiberboard HDF. A relief pattern is fashioned out of this layer by a special CNC milling machine, for acoustic reasons.
This relief is reminiscent of the external design of JBL studio monitors, where it is used to diffuse and break up room reflections that bounce back to the speaker s surface.
This all works superbly well. Clean in this case does not mean sterile or austere, but as already indicated, quite the opposite. Albarn s wonderfully mature voice, its fractures, its Northern Soul, as well as the feathery wind, the subtle electric elements of the recording everything flows. Although not uniformly; but. Field coil or independently excited drivers are products from a seemingly bygone era. Following is a short history of the loudspeakers: Werner von Siemans developed the basics for electrodynamic loudspeakers in The model for modern speakers, however, was envisioned by Rice and Kellog for Western Electric in , with a prototype that had a moving voice coil connected to a cone diaphragm.
This results in attraction and repulsion, and movement, in relation to the AC flowing through the magnetic field surrounding the coil. Because of the lack of strong permanent magnets, active field coils were used at the time. The first permanent magnet loudspeakers on the market were designs by Paul G.
H Voigt for his company, Lowther Voigt, in And since the s essentially only permanent magnets have been used. The beautiful irony of the story is that Wolf von Langa s first field coil driver which he purchased in was a wide bandwidth Voigt. This is where he perhaps passed through his last musical door. Why does the drummer play against the bass line, and why do the musicians play together at all?
After asking himself, he understood at once. Just as I do now. In fact there s a bit of black magic, when I, for example, play Captain Beefhearts album Trout Mask Replica Straight Records two record set in its full depth and its absolute originality, and for the first time am not tired after a short while or find I ve had enough.
It was this experience and others like it that made it especially clear to von Langa that reproduction quality had something to do with the fact that the drive system must be constantly fed. The modulation of the magnetic field through the voice coil had apparently assumed much greater significance for the sound than ever before. With permanent magnets there is a duration to the movement of the mass, therefore these magnets tend to constantly slow down and accelerate again.
The active field coil compensates for this modulation by keeping the current constant. As a result, it is much easier for the driver to follow all of the musical information. Another indispensable component of Langa s solution is supplying the field coil driver with a current source. This is not done in most independently driven designs, because there is a cost attached to the use of a current source: transformers, rectifiers, and capacitors for filtering, then with more costly solutions there is additional filtering, coils, and inductors.
But the current flow always remains variable. Von Langa adds, the field coil heats up and this definitely happens , which increases the electrical resistance while the current decreases at a constant voltage until stasis occurs. So the magnetic flux density changes. This is largely due to the field coil s resistance, which affects the speaker s overall Left: Intricately made laboratory power supply for the field coils, tuned by the von Langa company Right: Separate bass and mid high frequency speakers are connected in series PDF image-hifi.
The term colored bass is a case in point. I grew up with boomy, dull, or hollow bass. My childhood friend and I spent a lot of time listening to loudspeakers from a well-known German manufacturer.
Whenever my friend would leave the room, I d stuff socks in the bass reflex tubes, and as a result the low end became more precise. I now finally understand what color associated with bass response means in this case precise, agile, and multilayered. Bass like I have never heard before. As if performing on a long rubber rope, it follows the music alertly and with elasticity, always in the moment, always in the here and now, and ready quality; and all related parameters change unintentionally.
Only with a regulated, and readjusting current source does the field remain constant. This is achieved by the use of a von Langa modified laboratory power supply from the Far East. In the future he will have his own power supply, which will be manufactured in Germany. Currently the company offers a power supply upgrade, a constant current unit called the FCA.
My goose bumps tell me that I don t necessarily need it. And I thought maybe it s just one more of many technical assertions, or even a marketing ploy. Particularly if the technology wasn t immediately able to prove itself in terms of musicality.
Describing sound is always a subtle task. Another example: I was recently able to see jazz bassist Buster Williams in a live performance, and experienced the most imaginative and appealing acoustic double bass I ve ever encountered in my over thirty years of going to jazz concerts. The LP itself is not all that well recorded, but the aura of the film and its music, as well as my concert impression, provided an immediate recognition. Ventilated, light, and stiff.
This lesson in jazz funk sent me on a journey through time to the best acoustic stage performance I ve ever heard in all my concert going life Lee Scratch Perry in Amsterdam s Westergasfabriek.
At this appearance he stacked and layered instrument to instrument, location to location, one to the other. All clearly retained their uniqueness the guitar riffs, the tight, not at all boomy bass, the different drum sounds, the rhythm, the interplay, and the breaks.
So it was with Herbie Hancock s intricate music. His electric bassist, Paul Jackson, brought me to dance in my listening room with his heavy grooves.

Beyond the Ariel
This is not only affirmed by every single listener and modern simulation programs, but also by plain common sense. Just like power is generated in the motor, not the wheels. The translation from electric power to kinetic energy happens in the motor as well, and this is, why we have crafted a great idea. Explorers, curious listeners and music lovers have potentially already heard of us. You should be one of them. Which slogan was once used by a big German car manufacturer? EUR ,00 excl. The voice coil is ventilated.

It has become well known that electric cars accelerate much faster than their counterpart with combustion engines. This circumstance also applies to the topic of loudspeakers. The most important part of a loudspeaker is the drive unit or accelerator, even if the industry wants to make people believe that the cone is of the highest importance. The difference of WVL loudspeakers transducers, chassis to other loudspeakers is the drive itself. Yes, there are others who offer field coil speakers.
