Positioning the latest MPD (Micro-Pleated Diaphragm) III high-frequency transducer between twin RDT (Rigid-Diaphragm Technology) III 4 ¼” bass-mid drivers, while a highly optimised third-order crossover ensures the perfect frequency response across each drive unit for total symmetry, which helps control sound dispersion. The resulting high-fidelity sound is of a scale and quality that belies Studio 89’s size. Find out more at monitoraudio.com/studio-89 #MonitorAu
