APDA-ALTI Education Symposium 2023. Three Days of Audio Product Knowledge

The Audio Product Development Alliance (APDA) in association with the Audio & Loudspeaker Technologies International (ALTI) Association, promotes a three day education symposium during the ALTI Expo & Conference 2023, June 11 - 13, 2023 at the DoubleTree by Hilton at the entrance to Universal, Orlando. Three days to improve your knowledge and skills in the development of audio products, from concept to delivery.

The Klippel Near Field Scanner System (NFS) was used for the critical testing and measurement of Holoplot's X1 Matrix Array compensation algorithm capabilities. All our readers who have appreciated the story of the development of the unique Holoplot technology, published in the September 2022 issue of audioXpress, will enjoy reading about how Klippel and Holoplot worked to overcome frequency absorption and gain reduction challenges that resulted from the need to conceal the X1 systems behind an acoustically semi-transparent projection panel.

This article illustrates how the latest Klippel Multi-Scanning Workbench solution allows measurements across several domains (acoustical, mechanical, electrical, and magnetic) while working from non-anechoic environments. The author uses a practical characterization of balanced mode radiator (BMR) loudspeakers, which require a more complex approach when compared to conventional cone-based woofers or dome-tweeters. This article was originally published in Voice Coil, May 2021.

Precision Devices, the highly regarded "Made in England" manufacturer of high-quality loudspeaker transducers, just announced a brand new series of products. The company is using the forced interruption of normal support activities to intensify its work on refinements, new product development and improving production methods to its extensive portfolio. The results are now visible in new improved subwoofers, bass/midrange, and midrange drivers.

Klippel announced an exciting cooperation with Nuvoton Technology, a leading provider of consumer-electronics and computer ICs from Taiwan, to release a new type of smart amplifier with integrated Klippel Controlled Sound (KCS) technology that compensates for nonlinear speaker responses. As a result of the project, Nuvoton developed the highly efficient mono Class D audio amplifier devices, NAU83G10 and NAU83G20. Both devices are now available.

Following extensive research, Klippel GmbH has announced its new Klippel Controlled Sound (KCS) technology. This is an integrated approach that leverages the company's software and hardware tools for development, measurement and evaluation of new-generation loudspeaker systems, providing mechanical and thermal protection, automatic system alignment, active compensation of transducer nonlinearities and stabilization of the voice coil rest position. In other words, enabling research towards the speakers of the future.
