Exceptional headroom. Absolute authority. Three-Way Reference Architecture High Frequency — Beryllium Precision Two premium 2-inch throat compression drivers featuring beryllium (Be) diaphragms.

Featuring neodymium motor technology, these drivers provide substantial radiating area and high-output capability for demanding mid-bass reproduction.

Custom Cabinet Construction & Finish An extraordinary monitoring system deserves an equally extraordinary presentation. The Quad features a stunning white mother-of-pearl automotive finish with deep double-metallic flake, complemented by striking electric-blue wooden horns. The luminous cabinetry, brilliant metallic reflections, and sculptural horn assemblies create an unmistakable visual presence.
