Voice Coil Focus: Acoustical Characteristics of Adhesive Joints and Cone Treatments

There seems to be a lack of consideration and understanding of the acoustical characteristics of the loudspeaker’s many glue joints. In this article for Voice Coil, Mike Klasco and Steve Tatarunis detail how the influence and use of glue joints and diaphragm treatments can be used as a design tool. The report also details some significant new material options and design and measurement tools available. This article was originally published in Voice Coil, July 2017.

This edition focuses on Adhesive Joints and Cone Treatments and includes a special report on the latest new material options available and an updated directory of Adhesives, Coatings, and Sealant Providers. In our Spotlight article, Dan Knighten discusses the “Practical Measurement of Bluetooth and Lightning Headphones,” and in Test Bench, Vance Dickason discusses the new B&C Speakers DE990TN compression driver and Wavecor’s new SW168WA01 6.5” woofer. That and much more now available.
