A Fiber-Reinforced Composite Technology for Vibration Reduction in High-Performance Applications

This article, written by Anthony Caiazzo, Chief Technology Officer and Principal of Countervail Products, details the company’s family of vibration canceling materials featuring a patented approach that has been shown to provide exceptional levels of vibration damping in many common structural configurations. Countervail materials not only cancel vibrations, but they also contribute to the stiffness of the structure and typically don't significantly change the component manufacturing process.

Ferguson Hill Updates Jetstream Transparent Loudspeaker System

British loudspeaker designer Ferguson Hill announced that its Jetstream Loudspeaker System is now available and shipping as a complete system. The Jetstream, two decades in the making, builds on the seminal FH001 sound system. Twenty years after unveiling its debut system, Ferguson Hill's latest generation of the Jetstream maintains the extraordinary, transparent visuals; however, the Kent-based maker upgraded practically every single component of the original Jetstream Loudspeaker System.

Niron Magnetics: Green High-Performance Magnets Get More Green From Samsung

Back in 2020, Barry Vogel, the director of the Audio & Loudspeaker Technologies International (ALTI) Association called me excitedly about Niron Magnetics and about a new magnet material developed from research at the University of Minnesota. Iron Nitride (FeN) was perhaps the biggest news in magnets in 40 years. Composed of common elements — Iron and Nitrogen - the potential of permanent magnets from Niron could be a breakthrough and a game-changer for the audio industry.

COMSOL and Klippel, Integration of Simulation and Measurement Data

Modeling and Simulation and Measurement systems evolved significantly in the past decade. Important progress is now bridging the gap between COMSOL simulation and Klippel measurement data, Roger Shively reports after returning from Orlando, FL, where we attended another edition of the ALTI Expo & Conference (June 11-13, 2023). This article summarizes the content covered in a very important session as part of the APDA-ALTI Education Symposium 2023.

Dr. Kurt Müller Anniversary! 100 Years of Loudspeaker Innovation

Dr. Kurt Müller Anniversary! 100 Years of Loudspeaker Innovation

Mike Klasco writes about Dr. Kurt Müller's 100-Year Anniversary and revisits the milestones of this important supplier of cones, suspensions, dust caps and surrounds company. Perhaps the oldest surviving cone factory in the world and certainly one of the most advanced, DKM was originally founded in 1922, in Berlin, and in 1970, extended its product range with the acquisition of Pulsonic Ultrasonics Limited (now known as Kurt Mueller UK Ltd) in the United Kingdom. Happy Birthday!

Loudsoft FINE Suspension Nonlinear FEA Spider and Surround Design Program

An overview of Loudsoft's latest FINE Suspension Nonlinear FEA Spider and Surround Design software. This new transducer engineering tool, specific to the development of speaker surrounds and spiders (dampers), allows for the simulation of different types of surrounds and spiders from imported DFX files or created from templates with parameters selected by the user, and then outputs the compliance curves similar to the Kms and Cms curves measured by Klippel DA2 or KA3 analyzers.

Speaker Applications Using Alpine HX5 Ultra Strong Lightweight Nanocomposite

Loudspeaker designers can look forward to a couple of exciting materials that have been in stealth mode but are about to step into the spotlight. A lightweight military aviation-grade nanocomposite from Alpine Advanced Materials, HX5 may be an alternative to beryllium and high-performance aluminum alloys used in woofer, midrange, and full-range cones. Compared to aluminum, cones can be made at half the weight with comparable strength. This article was originally published in audioXpress, January 2022.
