Audiograde Calora










































With the CALORA, AUDIOGRADE presents the logical progression of its world-first loudspeakers cast from a single mold and with it the next stage of evolution in the history of handmade loudspeaker design in the 21st century. The CALORA was created with two seamless, fully-enclosed housings made from massive PolyGrade™ polymer concrete – a specially-developed and absolutely perfect acoustic material. Because in contrast to a musical instrument made from wood, an ideal loudspeaker cabinet produces no vibrations of its own even under extreme conditions.

PolyGrade™
Reference-quality sound through zero-resonance polymer concrete cabinet

The choice of cabinet materials for the CALORA strictly follows our highest ideal for uncomprising high-end reference loudspeakers. Our secret recipe is PolyGrade™ – a perfected special material taking advantage of the optimal qualities of concrete, thus offering a critical benefit over loudspeakers made from wood. PolyGrade™ is many times denser than wood and gives the housing of the CALORA an incredible resonance- and vibrationfree design – a fundamtental criterion of quality for high-end loudspeakers.
