Audio Technica AT-ART9XI Dual Moving Coil Cartridge

The “ART” in the model number stands for Audio-Technica Reference Transducer, a designation that we give only to our flagship phono cartridges. The specially designed magnetic circuit boasts an output voltage of 0.5 mV (1 kHz, 5 cm/sec), making the cartridge easy to use and capable of reproducing even the most delicate expressions, while also ensuring dynamic playback. The dual moving coils (fashioned from high-performance PCOCC wire) are aligned in an inverted V shape to provide high separation and wide response for clear sound localization and minimal distortion. Threaded cartridge mounting holes make installation to a headshell or integrated tonearm incredibly easy.

Featuring a special line contact stylus on a 0.28 mm diameter solid boron cantilever, the AT-ART9XI replaces the AT-ART9 as Audio-Technica’s flagship magnetic core MC cartridge.
