imgRome, Italy (March 26, 2013)—Wolfgang Klippel, developer of control and measurement systems dedicated to loudspeakers and tranducers, will deliver the Richard C. Heyser Memorial Lecture this year at the 134th AES Convention in Rome. The convention will be held from May 4 to 7 at the Fontana di Trevi Conference Centre.

The lecture, “Small, Loud-Speakers: Taking Physics To The Limit,” will address the challenge in engineering diminutive speakers that can also be loud, have high efficiency and low distortion. The loudspeaker is the weakest part of the audio chain, and the basic construction and principle of the moving coil speaker has remained unchanged for a century. However, understanding of its operation and limitations has increased considerably. Modern signal processing techniques, coupled with innovative design can create small drive units with optimum trade-off between the crucial design factors. An abstract of the lecture is posted at

“Considering our primary Convention Tracks: “Live Sound, Loudness, Spatial Sound, and Sound for Pictures,” Wolfgang Klippel’s presentation is particularly appropriate,” states AES Technical Council Chair, Francis Rumsey. “His lecture’s central topic will focus on cultivating large signal transducer performance. As a leader in research on transducer modeling, acoustic measurement and psychoacoustics, and as a pioneer in the development of critical measurement tools, Wolfgang Klippel is one of the most highly respected experts in the field.”

Celebrating its 65th year of leadership in the professional audio community, the 134th AES Convention marks the first major AES event to be held in Rome. “Arguably the very birthplace of engineering, our ‘Eternal City,’ will provide a richly historic setting for the world's top audio professionals, educators, and students,” Umberto Zanghieri, concludes.  “They will share the latest advances in audio research and practice, and a rare opportunity to listen, learn and connect with their peers, customers, and mentors.”
