Patent Review: Multiple Path Acoustic Wall Coupling for Surface-Mounted Speakers

This article reviews a patent awarded to Paul Wayne Peace Jr. and Derrick Rodgers, on behalf of Harman International Industries. The patent describes a surface-mounted loudspeaker design that mitigates the interference between direct low-frequency (LF) energy and reflected LF energy by breaking the LF energy from an LF driver into multiple paths using one or more of waveguides, driver load plates, and enclosure ports to diffuse the reflected energy and minimize frequency response errors.

Non-Linear Amplitude Modulation of Loudspeakers

Non-Linear Amplitude Modulation of Loudspeakers

Even a perfectly linear loudspeaker produces two types of distortions because of the movement of its membrane. First Doppler distortions, a.k.a. Phase Modulation (which the author addressed in his October 2024 article for audioXpress), and secondly distortions stemming from the Nonlinear Amplitude Modulation, characterized in this article. More importantly, this article also addresses how these harmonic and intermodulation spectral line distortions can be minimized and eliminated in loudspeakers.

Clean Earth Magnets Manufactured in Minnesota

Mike Klasco writes about Niron Magnetics' first commercial pilot plant in Minnesota. The opening of this 70,000 square-foot Minneapolis facility took place in October 2024 and is a key milestone in Niron Magnetics's path to scaled production of its Clean Earth Magnet technology and the company’s ability to bridge the acute supply and demand gap for permanent magnets. A significant step forward in the company's mission to produce sustainable, rare-earth-free permanent magnets.

Fresh From the Bench: IK Multimedia ARC Studio

With the ARC Studio, IK Multimedia introduced a new DSP market contender for room and speaker correction. The solution combines a processor bundled with the company's ARC MEMS microphone and new ARC 4 software. Although ARC Studio was designed essentially for the home studio, the market served by the Italian company, this review also explores the possibilities for stereo system users, seeking playback chain improvements.

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.

Loudspeaker Bass Reflex Alignments

Loudspeaker Bass Reflex Alignments

The use of standard filter alignments represents a foundational concept in the loudspeaker industry, with an impact nearly as significant as the invention of the electro-dynamic loudspeaker principle itself. As one of the creators of Speakerbench, a web-based speaker design tool, in collaboration with Jeff Candy, Claus Futtrup is in a unique position to discuss the evolution of enclosure designs based on this electrical filter theory, including the concept of an alignment chart.
