A Milestone in the History of Full-Range Speaker Technology!<br />
By conducting extensive studies as well as laborious<br />
and costly tests, we have finally managed to engineer a<br />
driver based on Dr. Podszus' famous rigid-foam diaphragm<br />
capable of reproducing the entire audible frequency<br />
range with breathtaking authenticity and transparency—without<br />
crossover network components.<br />
We made a conscious decision in renouncing a supertweeter<br />
as the resulting phase difference deteriorates<br />
the holographic imaging of this unique system. Only the<br />
lowest frequency bands are supported—by an extremely<br />
fast ZELLATON bass driver.<br />
Located behind a 6/1000 mm thin special aluminum film<br />
is a multiple-composite rigid foam of a top-secret composition,<br />
which is foamed at a precise predetermined and<br />
monitored temperature. The minuscule bubbles, which<br />
vary in shape, position and size, play a key role in the<br />
unique acoustic performance. A guarantor of authenticity<br />
and distinctiveness of ZELLATON loudspeakers, they are<br />
barely visible in the aluminum, much like the microscopic<br />
irregularities in a valuable precious stone. ZELLATON’s<br />
triple-layer diaphragm design avoids the disadvantages<br />
of other manufacturers' single-component diaphragms,<br />
which sound muffled or hard, depending on the material<br />
used, and lack the detailed resolution that characterizes<br />
our systems.<br />

Each of our broadband speakers is optimized by hand in a weeks-long process until they<br />
achieve the desired linearity and minimal partial oscillation which provide for extremely low harmonic<br />
distortion. In so doing, we have succeeded in combining the concept of an ideal point<br />
source with a symmetrical input signal while avoiding the phase shifts and disadvantages<br />
of crossover network components and coaxial operation. Moreover, this also avoids<br />
the partial oscillation and break-up as well as the resultant sound coloration of other systems,<br />
which generate the high frequency range with superposed elements (e.g. buzz cones). The result<br />
is a transparency and liveliness beyond description that wins over every listener.<br />
Professionals who work in sound studios appreciate the quality of this kind of technology, as it<br />
is indispensable in making accurate assessments of the quality of recordings.<br />
The ZELLATON Studio Reference One loudspeaker turns musical reproduction into a live experience<br />
and allows you to listen to music just how it was recorded!<br />

DRIVER TECHNOLOGY<br />
SR-1<br />
STUDIO REFERENCE ONE<br />
• Unique diaphragm technology by Emil<br />
Podszus, dating back to 1935: lightweight,<br />
torsionally stiff rigid-foam diaphragm<br />
with ideal unit pulse response<br />
• Painstakingly handmade in-house in Germany,<br />
from start to finish by a third-generation<br />
family member, Manuel Podszus<br />
• The production process requires an extremely<br />
sophisticated manufacturing technique<br />
with precisely defined process parameters,<br />
resulting in a high reject ratio.<br />
This ensures consistently high mechanical<br />
and visual quality<br />
• Each diaphragm takes several weeks to<br />
manufacture, in order to ensure optimum<br />
cell structure integrity and maximum rigidity<br />
paired with minimal weight. Diaphragms<br />
hand-ground on a grinding disc<br />
• Three-layered diaphragm, featuring<br />
materials with varying degrees of acoustic<br />
transmission (sandwich construction)<br />
• All materials and adhesives used are subjected<br />
to several months of tests for optimum<br />
performance<br />
• Use of extremely robust industrial adhesives<br />
featuring outstanding long-term stability.<br />
Adhesives and coatings are cured for<br />
several days<br />
• 6/1000 mm - thin aluminum film (extra-soft<br />
alloy) with extremely balanced acoustic<br />
characteristics (exceedingly difficult to handle<br />
as the film can tear immediately when<br />
processed)<br />
• Limited Annual Production due to<br />
extremely long manufacturing time<br />
• ZELLATON has created an unprecedented<br />
7” widebander mated to an 9” woofer for<br />
a result which is out of this world<br />
• Newly engineered Linear 7” fullrange<br />
driver with filterless signal<br />
path (symmetrical input)<br />
• Full-cone 9” woofer with acousticallymatched<br />
hard aluminum film and fast,<br />
passive 6dB crossover network<br />
• Proprietary spiders and surrounds<br />
• Computer-optimized magnet systems<br />
with a largely linear field along the entire<br />
height of the pole plate<br />
• High-temperature coils on titanium films<br />
guarantee optimal unit pulse response<br />
• Significant reduction in wobbling through<br />
dual centering for an extremely linear<br />
throw<br />
• All parts are machined from a single<br />
workpiece - a very costly process that<br />
avoids transition resistance<br />
• All drivers go through a break-in period<br />
before each driver is fine-tuned for hours<br />
until it produces an ideal frequency response<br />
• Every single driver is subjected to multiple<br />
control measurements and fine adjustments.<br />
Each frequency response is<br />
logged and documented. Documentation<br />
of all drivers shipped guarantees yearslong<br />
service<br />
• Pairs matched to the smallest of tolerances.<br />
Individual fine-tuning using flow<br />
resistors<br />
• No-compromise selection of Duelund<br />
Coherent Audio and Mundorf crossover<br />
network components<br />
