In all the larger models, the intelligently designed loudspeaker cabinets guarantee the utmost in neutrality. In order to attain a comparable degree of signal fidelity, the cabinets on the Classic models are designed as a sandwich construction made of several materials.
The inner layer, 12 millimeters thick, consists of MDF that possess excellent dampening properties. Depending upon the design chosen, the Classic 20 outer MDF panels are finished in fine wood veneers. The special feature in this case is a two-millimeter middle layer between two layers made of closed-cell high-tech acrylic resins. This design, similar to double glazing, helps to lend the walls of the Classic 20 unusually low sound permeability – and thus interrupts the direct transmission of noise emitted in the cabinet interior through the panels of the loudspeaker to the outside. Little attention has been paid to this phenomenon, referred to as sound penetration, up to now, but in fact this effect may have a strong influence on the original signal. The joints created by the sandwich are a design element of the loudspeakers. The softer core works as a buffer zone, influencing adjacent materials that are more prone to resonance, transforming any partial vibrations immediately into thermal radiation.
As an alternative, we offer the Classic 20 as high-gloss versions in black and white. Instead of MDF, the high-gloss versions have exterior panels made of glass. Here as well, the use of an extremely effective adhesive eliminates any possibility of the glass surfaces developing their own acoustics – the dreaded "ringing effect" associated with glass is nipped in the bud. All the advantages of using glass as a material, such as its incredible stiffness, are fully retained. Due to the new cabinet technology, the sound performance of the Classic models come very close to the virtues of other higher priced models in the line and they simply set a new standard in their price segment.
The stunning design feature of the re-designed Classic 20 is that the woofer is no longer placed on the sides of the loudspeaker, but rather – like its big sister, Classic 30 – in its own compartment inside the cabinet. This offers visual and technical advantages: On the one hand, the side panels of the Classic 20 now create a visually homogeneous unity whose contours are not interrupted. On the other hand, using an intelligent bass configuration with the woofer being mounted in its own compartment further reduces the impact of vibrations on the surrounding body. Combined with the bass reflex system integrated in the cabinet concept, this enables an incredibly precise and stunning low-tone fidelity with a powerful punch. A look at the transparent illustrations of the Classic 20 and the bass module reveals the sophisticated configuration of the woofer near the base and the elaborate struts inside the cabinet that hardly diminish the inner volume, however. The listener is rewarded with not only highly-profound, accurate basses, but also with remarkably high definition and clarity in the mid-ranges and trebles.
These precise qualities are also brought out by the newly-developed mid-ranges and tweeters; veritable high-performance drivers. Their architecture has been trimmed for maximum signal fidelity. The new midrange driver boasts narrow cone mounts, a fixed phase plug, an over sized drive and a fiber reinforced paper membrane. The perfect interaction of all components provides for neutrality and stability in the so vital mid-ranges that is uncommon for this class. The modern tweeter, with its fabric cap, reproduces frequencies ranging far above 20 kilohertz linear. It is surrounded by a radial felt mat shaped like a star, which facilitates uniform sound dispersion.
As with the more expensive models, we are using the technologically advanced WBT nextgen™ terminals as standard even in our "smallest" line. It is only logical and consistent, as these connectors, through their clever conductivity, eliminate ground storage effects and also noticeably minimize micro vibrations.
