Headphone Testing (Part 1): The Basics

In this article, Steve Temme discusses the issues that are common to testing all types of headphones. As more and more loudspeaker engineers find themselves employed in the fast-growing headphone market, it is important that the unique challenges of testing headphone packages are fully understood.

Measurement and Perception of Regular Loudspeaker Distortion

Measurement and Perception of Regular Loudspeaker Distortion

This article discusses the physical causes of regular loudspeaker distortions, their modeling by using lumped and distributed parameters, the objective assessment using modern measurement techniques, and the perception by the human ear. Article originally published in Voice Coil, May 2011

Driver Selection for Multi-Way Speakers

Driver Selection for Multi-Way Speakers

Speakers evolved from a single sound source to having separate low-frequency and high-frequency drivers, each optimized for its own frequency range, to multi-way designs, with additional low-mid, high-mid and even super-high frequency drivers. Dr. Richard Honeycutt explains how to optimally choose these drivers. This article was originally published in Voice Coil, January 2012.

New Drivers from Eighteen Sound at Prolight+Sound 2015

The Reggio Emilia loudspeaker specialist was in full force at the 2015 Prolight+Sound show in Frankfurt with an impressive display of new products in its catalogue. New for this year, the 8CX650 and 10CX650 coaxial loudspeakers, announced earlier in the year, are now shipping. But there’s also the ND4015Ti2 compression driver, the XG10 line source waveguide and much more.

A Look at Voice Coil Collars

A Look at Voice Coil Collars

There are many subtle ways a speaker designer can use the collar to “tune” the speaker-design for optimum response, added strength, increased thermal tolerance, better assembly fit, and more. Many materials are available for use as a collar but a careful understanding of the physical properties of these materials is required for optimum selection.

Loudspeaker Sensitivity: What’s a Watt, Anyway?

Loudspeaker Sensitivity: What’s a Watt, Anyway?

The specification of a loudspeaker’s sensitivity is probably one of the most common, yet perhaps one of the most misunderstood. In the past, and still today, it is common to see the magnitude response of a loudspeaker system reduced to a single number as a sensitivity rating.

Understanding Horn Directivity Control

Understanding Horn Directivity Control

Horns are often used in loudspeaker systems for a variety of reasons. One may be to provide increased acoustical loading to the driver attached to the horn. This helps to increase the sensitivity/efficiency. Another may be to provide some control over the radiation pattern of the driver attached to the horn.

Voice Coil Spotlight: The Beryllium Advantage

Since its formation, VUE Audiotechnik has been engaged in a strategic development partnership with Materion Electrofusion, the world’s leading supplier of genuine beryllium. This article explores beryllium as a high-performance alternative to aluminum and titanium. Originally Published by Voice Coil, April 2013

Characterizing the Microspeaker Industry

March 11, 2015 by Mike Klasco

Characterizing the Microspeaker Industry

Microspeakers are manufactured predominantly in Asia. Many microspeaker manufacturers in Taiwan, Korea, and Hong Kong started in the 1970s with buzzer production, which included household appliances, automotive warnings, telephone ringers, and so forth. Mobile audio products have increased microspeaker consumption and stretched the microspeakers’ sound quality requirements.
