Fast, Quality Testing of Loudspeaker Suspension Parts

This article discusses an approach for time-efficient testing of loudspeaker suspension parts, close to their final operating conditions. It refers to the Linear Suspension Test set (LST Lite), a hardware and software add-on for the Klippel QC loudspeaker end-of-line testing system. The system may be applied to 100% of the parts or to a random sample. This article was originally published in Voice Coil, December 2012 (with some updates introduced from 2019 documents).

Peter Thomas Is Honored By The Institute of Professional Sound

PMC’s founder and CEO Peter Thomas, whose inventions have helped push the boundaries of modern loudspeaker design, has been awarded a Fellowship by the Institute of Professional Sound (IPS) and awarded a coveted IPS trophy in recognition of his contribution to the professional audio industry. The Institute recognizes Peter Thomas transformative work, and significant impact on the audio industry through pushing the boundaries of monitor design to achieve more accuracy, particularly at higher volumes.

Redefining the Shape of Sound: Resonado Introduces Flat Core Speaker Technology at CES 2020

Redefining the Shape of Sound: Resonado Introduces Flat Core Speaker Technology at CES 2020

Resonado, a South Bend, Indiana company founded at the University of Notre Dame, has a new take on electrodynamic speaker topology. The company developed a reconfigured speaker with a planar voice coil mounted perpendicularly to its flat “race track” diaphragm, to which Resonado calls Flat Core Speaker (FCS) technology. The ingenious architecture enables slightly thinner, lighter, and more efficient speakers than conventional equivalents. Applications are wide-ranging from soundbars, home theater, column speakers, automotive to headphone drivers.

ISEAT 2019 - International Symposium on ElectroAcoustic Technologies - A Report from the Center of Global Speaker Manufacturing

ISEAT 2019 - International Symposium on ElectroAcoustic Technologies - A Report from the Center of Global Speaker Manufacturing

Loudspeaker engineers have few choices for professional forums. The Audio Engineering Society (AES) is an outstanding international organization although not entirely focused on speakers. ALTI (formerly ALMA) is loudspeaker-centric but does not have a strong base in China. And although you may not have heard about iSEAT, for most Chinese speaker engineers that is their preferred professional organization. The International Symposium on Electro-Acoustic Technologies (ISEAT), founded in 2007, is held every two years and has successfully conducted six sessions.

Loudspeakers for Vented Enclosures: A Backward Approach for Speaker Selection (LoVE BASS)

Loudspeakers for Vented Enclosures: A Backward Approach for Speaker Selection (LoVE BASS)

In this article for Voice Coil, the authors explore the problem of designing vented enclosures, describing a backward concept they call LoVE BASS, which they found to save a substantial amount of engineering hours during the process of speaker box design. As opposed to taking a given driver and designing an enclosure, the authors define the system’s target performance in terms of physical volume, lower cut-off frequency, ripple and maximum achievable SPL, after which they look for candidate drivers that allow for such a design. This article was originally published in Voice Coil, July 2019.
