Amadeus Unveils New C3 and C4 Miniature Speakers

Amadeus has unveiled their new shallow-depth point source miniature speakers. The C Series was created in 2018 through a specific custom development for performing arts venues, carried out in coordination with the technical sound team from the Paris-based Chaillot National Theater. The new C3 and C4 miniature speaker models are available now for ordering from Amadeus and can be used for many applications.

The AudioChiemgau ModeCompensator: A Quick Basic Test

The principles applied by Dr. Reinhold Lutz's for precise measurement of the sound pressure frequency response in the presence of room modes, are available in its AudioChiemgau Mode-Compensator solution. Jan Didden and Rens Tellers did a basic functional test to find out how well they could make it work and they were pleasantly surprised with the results. This article was originally published in audioXpress, October 2023.

Measuring Loudspeaker SPL Response and Harmonic Distortion at Low Frequencies
November 8, 2023 by Reinhold Lutz

Measuring Loudspeaker SPL Response and Harmonic Distortion at Low Frequencies

This article discusses how to measure loudspeaker SPL response and harmonic distortion at low frequencies in a standard environment, full of reflections from acoustically hard boundaries (e.g., walls, floor, and ceiling), room resonances, and even ambient noise reducing the dynamic range and accuracy of the measurements. The method combines near-field measurements with two identical microphones. This article was originally published in audioXpress, October 2023.

Simulation Techniques: Loudspeaker Driver Displacement Decomposition

This article by René Christensen (BSEE, MSc, PhD), offers a valuable tutorial that discusses the unique possibilities of three-dimensional analysis of loudspeaker driver displacement, using Phase Decomposition and Axial-Symmetrical Decomposition techniques. The article demonstrates how a total displacement on a cone surface can be decomposed into different components directly in COMSOL Multiphysics, and how this can reveal some of the underlying mechanisms of the driver.

Voice Coil Patent Review: Two Key Resonado Patents

James Croft looks at two patents from Resonado Labs, the young speaker company that has been pursuing a new speaker topology — originally called Flat Core Speaker (FCS), and now rebranded as Res-Core — using a reconfigured speaker with a planar voice coil mounted perpendicularly to its flat diaphragm. This review covers two of the company's patents granted in 2022, titled "Speaker Comprising Split Gap Plate Structure," and "Flat Speaker Driven by a Single Permanent Magnet and One or More Voice Coils.".

TAD Labs Introduces TAD-GE1 3-Way High End Speakers

Technical Audio Devices Laboratories (TAD Labs) announced the TAD-GE1 (Grand Evolution One) speaker system as the newest addition to its Evolution Series of hifi audio components. Borrowing internal technology and design language from TAD’s top-of-the-line Reference TX Series as well as the distinguished wood-grain finish of the standmount CE1TX speakers, the new GE1 floorstanding speakers feature a coaxial driver with a magnesium diaphragm midrange and beryllium tweeter, and second generation multi-layered aramid composite woofers.

Patent Review: Radial Acoustic Speaker

In this article, James Croft discusses a patent granted to Curtis Graber (Woodburn, IN) that describes a radial acoustic speaker assembly including a transducer and a plurality of segmented spiral horns acoustically coupled to the transducer, each with its acoustical path. This new patent by prolific audio inventor, Curtis Graber, uses a new multi-spiral waveguide structure driven by a single transducer and has clear advantages over prior art. This article was originally published in Voice Coil, May 2018.

Patent Review: Two Pioneer Patents. Same Speaker Invention

Patent Review: Two Pioneer Patents. Same Speaker Invention

This article reviews two patents titled simply "Speaker Device" from four Japanese inventors, on behalf of Pioneer Corp. of Japan. The original and expanded patent describes a flat speaker device capable of emitting loud reproduced sound, using a mechanical structure that converts a linear voice coil motion in one axis to an orthogonal mechanical diaphragm displacement. The system functions much like a scissor-jack you would use to raise your automobile to change a tire. The linear motion of the threaded rod coverts the axial force to a 90° lift movement.
