Our neodymium tweeter is a descendant of our coax technology, a result of permanent evolutionary development

Over the years Vienna Acoustics had found the best sounding tweeter, a refined development in cooperation with the danish specialists from ScanSpeak. But the superior technology is the point source, and that tweeter was too big, so over the last 2 years the goal was to develop a neodymium version which sounds the same as the reference or better. This was not only achieved, but on the way a super-tweeter extension was realised, with outstanding resolution without compromising the smooth and natural overall characteristics of the original tweeter. Originally developed with neodymium magnets to decrease its size with zero compromise, it is unmatched in uncoloured and neutral sound as the stand alone version as well.

Three 7” Spidercone bass drivers (or ULF, Ultra Low Frequency, drivers) – also found in our famed LISZT speaker -, feature a reworked motor assembly and revised placement of the X3P ribs, providing increased output, extension and control.

The huge surface area that results from the use of three of these extraordinary drivers means effortless reproduction of extreme bass dynamics with articulation and force.

Our cabinet utilizes several braces that divide the cabinet into two different chambers, one with a single woofer and the other with two woofers, each vented and uniquely tuned. The two lower units produce the lowest bass, working in parallel, while the single driver provides ideal transition to the midrange driver.

The midrange driver of our Beethoven Concert Grand Symphony Edition features a cone with the Vienna Acoustics proprietary mixture “X3P” of TPX and 3 polypropylene based synthetics , for maximum inner damping.

It combines the precision and transparency of hard cones – such as stamped metal – with the smoothness and musicality of sof­ter materials. One of the secrets is the right share of polypropylene which gives the optimum in stiffness and inner damping ratio.

The final sonic improvements as a result of these collective changes are greater clarity, speed as well as greater bass extension without giving up any of the famed musical quality and rhythm inherent in all our designs.

All of our individual crossover components are of the highest quality, chosen exclusively by listening tests. As a result, our designs feature very expensive handpicked capacitors, and metal-oxyd-film resistors with less than 1% tolerance are chosen for their freedom from inductance.

The differences in resolution and spaciousness between capacitors that have identical measurements and identical material, but are produced by different manufacturers, can vary unbelievably. While our crossover components are chosen purely on the basis of their contribution to sound quality, we have identified another area of sonic variance in other designers’ speakers.

Even the tiniest variations in coil inductance may dramatically affect width and depth reproduction in the soundstage. We have eliminated this issue by winding our special air core inductors using a specially designed robot able to hold a tolerance of only 0.7%. The resulting improvement is decidedly worth the effort.

The Base Assembly

Our new Beethoven Concert Grand Symphony Edition features a brandnew base-foundation. The carefully manufactured devise is created by using a high-pressure aluminium die-casting and designed for greatest stability and optimized decoupling of the speaker.

As with all our models of the Concert Grand Series speaker systems, we have perfected a real-wood veneer process that to our opinion is exclusive and unrivaled: the membrane press / handcrafting veneer wrapping technique.

Through years of experience working with real wood and real-wood veneer techniques, especially for curved baffles, Beethoven Concert Grand Symphony Edition is meticulously handcrafted to the highest standards of quality in Vienna, Austria, with each finished speaker matching the reference within 0.3 dB, to ensure the most effortless and natural performance from every speaker that leaves our factory.
