Klippel Controlled Sound (KCS) - Controlled Sound Technology for Nonlinear Compensation of Loudspeakers

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.

Beyond Thiele/Small DUMAX and Klippel Driver Measurement Systems

Anyone who is serious about designing a loudspeaker using dynamic drivers is either familiar with, or has used, Thiele/Small parameters, generally accepted as ways to predict driver behavior in different enclosures. But there are other measurement methods we can use to determine and quantify nonlinearities: the DUMAX system, produced by DLC Design, and the Klippel Analyzer System by Klippel GmbH. This article was originally published in audioXpress, March 2003.

Meyer Sound Introduces M-Noise Test Signal for ‘Real World’ Loudspeaker SPL Measurements

Meyer Sound Introduces M-Noise Test Signal for ‘Real World’ Loudspeaker SPL Measurements

Meyer Sound has introduced M-Noise, a new test signal that will promote standardized measurement of a loudspeaker system’s maximum linear output. A mathematically derived test signal that effectively emulates the dynamic characteristics of music, according to Meyer Sound, M-Noise enables a far more accurate measurement of a loudspeaker system’s linear peak SPL in any application requiring reproduction of musical content.

HEAD acoustics Introduces HQS-Audio for Comprehensive Testing of Loudspeakers, Headphones and Audio Systems in Vehicles

HEAD acoustics, one of the world's leading companies in the field of voice and audio quality optimization, introduced HQS-Audio, a new tool for its ACQUA analysis system that provides whole set of targeted electroacoustic measurements and helps to comprehensively test the quality of audio devices. Whether loudspeakers, headphones, or audio systems in vehicles, HQS-Audio provides independent test runs for each application, consisting of various electroacoustic measurements, including Thiele-Small parameters.

Measuring Loudspeaker Low-Frequency Response

Measuring Loudspeaker Low-Frequency Response

With the availability of low-cost, PC-based acoustic data acquisition systems, experienced hobbyists can make highly accurate loudspeaker frequency-response measurements without an anechoic chamber. The power of these systems comes at a price. These systems window the time-domain measurement to eliminate room reflections. This, in turn, limits low-frequency response. This article was originally published in audioXpress, June 2012.
