Posted in: History | Technology

The 3rd generation Micro Pleated Diaphragm (MPD III) high-frequency transducer redefines what is achievable for high-end home audio. Developed by Monitor Audio’s acoustic engineers when creating the company’s ground-breaking ‘Concept 50’ prototype, this breathtakingly accurate tweeter was unveiled for Monitor Audio’s 50th Anniversary celebrations.

  • Micro Pleated Diaphragm (MPD) extends tweeter passband to >60 kHz (compared to >40 kHz for a typical AMT)
  • Square radiating area ensures equal directivity in horizontal and vertical planes, resulting in an improved soundstage
  • Optimised rear volume to ensure minimal ripple in audible frequency range, with gentle rise on-axis to deliver exceptional detail
  • Optimised waveguide to give controlled directivity and radiation impedance matching, further improving soundstage and maximising sensitivity

The MPD III Tweeter delivers a larger, clearer, and more consistent sound. Music and film are delivered with precision and clarity, allowing the listener to enjoy levels of accuracy and detail beyond what they have experienced before.
