Piega Coax Gen2
The Swiss speaker specialist expands its successful Coax series with four brand new models and, at the same time, presents a technically refined limited edition of the already well-known Coax floor-standing and bookshelf speakers. "Noble aluminum enclosures and ribbon loudspeakers" would probably be the answer of most hi-fi fans if you were to ask them about the most important features of Piegaloudspeakers. The four brand-new models, Coax 811, 611, 411, and Center 211 feature these characteristics and offer numerous technical innovations that significantly enhance the sound quality of the quartet.
Ever since the company was founded in 1986, Piega has relied on ribbon tweeters in its loudspeakers. Their diaphragms consist of a wafer-thin aluminum foil that is 30 times lighter than conventional domes, thus enabling exceptionally spatial and detailed high-frequency reproduction. Later, the Swiss brand expanded its chassis technology to include a combined mid-treble ribbon with a tweeter placed centrally in the middle of the surrounding midrange driver - the Piega Coax series was born.
An enhanced version of this unique coaxial midrange tweeter is now at the heart of the new Coax models. Its redesigned solid front panel features additional cross-bracing and a center bridge, which allows the installation of an additional neodymium magnet above the tweeter to improve its efficiency further. In addition, a newly developed, specially coated foil is used, which allows a more linear frequency response in the lower frequency range and thus a deeper connection to the woofer. The coaxial ribbon now takes over reproduction from 450 Hz and also covers the sensitive range of vocals within its wider frequency band, which can now be reproduced absolutely flawlessly and harmoniously.
The inner workings of the coaxial driver have also been meticulously optimized down to the last detail. The magnetic rods are now mechanically decoupled to prevent even the smallest changes in the magnetic field caused by micro-resonances. From the layout of the foil and the magnet design to the damping of the mechanical construction, nothing has been left untouched, and each element is precisely tuned to the others. The audible result is impressive with even more dynamics, more refined details, and outstanding spatiality, the Coax Gen2 series sets new standards in the mid-high range.
To meet this high-quality standard at lower frequencies, the already outstanding UHQD woofers in the new coax models have been given more "room to breathe". The cabinets are made of an extremely high-quality, now even larger seamless aluminum extrusion. The Coax 811 has the most opulent profile ever used in loud-speaker construction, with a circumference of 119 cm and a wall thickness of 12 mm. Already in the previous Coax series, the "Tension Improve Module" (TIM) developed by Piega puts the loudspeaker cabinets under controlled tension by applying targeted pressure to the inner walls in order to effectively suppress unwanted cabinet vibrations. To further significantly increase the rigidity of the enclosure, the new TIM2 module, used for the first time in the Coax Gen2 series, is placed under tension and positively connected to the enclosure. In this way, even minimal cabinet vibrations can be reduced extremely effectively, and the remaining resonances can be completely eliminated by the proven viscoelastic damping foils.
After the successful Ace series, Roger Kessler, Head of Research & Development in the Piega team, is already responsible for the second speaker line with the Coax 411, 611, 811, and Center 211. And thanks to the elegant and timeless creation of Swiss designer Stefan Hürlemann, the new Coax Gen2 series will be an absolute eye-catcher in any room. Prices start at €3300 for Coax 311 LTD and go all the way up to €13450 for Coax 811. Info and photos by Piega.
