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. Likewise, 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 the HIGH-END line and they simply set a new standard in their price segment.
