AUDIOGRADE AG is a German high-end loudspeaker manufacturer founded in 2010 by chief developer and founder Wolfram Szentiks, based in Aachen, Germany. The company revolutionized speaker design by creating the first loudspeaker with monolithic cast concrete cabinets, though later evolved to special polyurethane compound cabinets that are almost as dense as concrete but easier to machine. Their flagship ARDORA speakers feature distinctive wave-shaped cabinets designed to prevent standing waves, ceramic drivers with proprietary Waveguide technology for expanded sweet spots, and extremely low distortion factors. All speakers are fully manufactured at company headquarters using in-house CNC machine parks and extensive electronics laboratories, allowing complete customization including room measurement/correction techniques and custom colors/surfaces. The company philosophy 'performing acoustic visions' reflects their commitment to speakers as both acoustic and visual works of art. AUDIOGRADE has received recognition as a trade show discovery, celebrated for delivering technically and sonically maximum performance for the price point.
