High End from a single mold

AUDIOGRADE is a young German high-end manufacturer that produces the world’s first and unique loudspeakers from a seamless cast housing with innovative materials and revolutionary manufacturing processes. With the stand-by loudspeakers APOLLO, ARDORA and CALORA, AUDIOGRADE offers its demanding customers complete masterpieces, all around in sound and visual terms, which are produced by hand in the Aachen manufactory with an exceptionally high depth of value added.

Performing acoustic visions

The ARDORA is the brilliant result of intensive material research at the highest level and embodies the central element of THE company philosophy of AUDIOGRADE: the creation of a high-end loudspeaker from a resonance-free and thus acoustically perfect Housing. Unlike a wooden musical instrument, an ideal loudspeaker prevents sound from leaking through its housing walls and does not produce any disturbing vibrations. AUDIOGRADE therefore relies on a seamless cast of solid polymer concrete and provides the all-ceramic loudspeaker drivers with an optimal basis for flawless sound reproduction.

The experts agree

AUDIOGRADE is ‘The Discovery’ [Stereoplay] and enjoys an excellent reputation among connoisseurs as a steadfast company with innovative products and a sustainable vision. AUDIOGRADE CEO Wolfram Szentiks is responsible for the development and manual production of all products, who has been developing and constructing elaborate loudspeaker concepts from an early age. After studying electrical engineering and intensive professional experience as a software and hardware engineer, Szentiks realizes his lifelong dream and, with the support of a top-class team of experts, establishes his own high-end manufactory at the world-renowned Industrial and research location Aachen.

Conceived & handcrafted in Germany

An essential cornerstone of AUDIOGRADE’s guiding philosophy is the constant dialogue with internationally sought-after coriphäen from the field of professional audio technology. Specially manufactured CNC machines and a laboratory environment in which almost all components are developed, tested and individualised according to exclusive customer requirements ensure a high depth of value creation. In a room-like listening room, each loudspeaker with experienced and trained ears is finally checked under real conditions and then delivered with a measurement certificate.


AUDIOGRADE has already defined new high-end standards and significantly revolutionized the high art of handmade loudspeaker construction. The key to good sound lies in the uncompromising implementation of unique concepts, both for their own products and for well-known companies that rely on highly specialized solutions from AUDIOGRADE. As a result, Wolfram Szentiks and his team are already working on groundbreaking ideas of tomorrow and can look ahead to the further expansion of an internationally active distribution network in order to ensure continuous growth of the manufactory in the long term.
