Improving the Transfer Function of Electrodynamic Loudspeakers

This article compares motion feedback technologies applied to speakers. A recognized expert in this field, Reinhold Lutz explores how to achieve a nearly perfect electro-acoustic transfer function, including a detailed control strategy of different types of sensors. A great exploration of how a closed-loop feedback system is able to improve loudspeaker linearity.

Klippel now officially distributes and supports the MegaSig U980 professional Bluetooth interface. Together with the Klippel Analyzer System, this USB-controlled, analog signal converter supports reliable testing of any audio device enabled with Bluetooth wireless technology such as portable speakers, wireless headsets, and true wireless earbuds with a fully integrated solution for both lab and end-of-line context.

Klippel's software dB-Lab version 210, the unified framework for R&D and QC audio testing, diagnostics and simulation, has received a free maintenance update.
