Voice Coil June 2021 explores the CTA-2010 Standard Method of Measurement for Subwoofers, and follows with a scheduled directory of Headphone Test & Measurement Equipment suppliers and solutions. James Croft reviews an interesting patent exploring a combination design with dual-diaphragm compression drivers, and Vance Dickason characterizes the much-anticipated SB Acoustics Satori MW16TX-8 Textreme Cone 6.5" Woofer, and the very original BDNC BGF-46166-18-4-003 Glass-Composite Diaphragm Woofer. Now available in print and digital.

Resonado Labs is ready to bring to market its patented speaker technology. This article describes Resonado's core Flat Core Speaker (FCS) technology that uses a reconfigured design with a planar voice coil mounted perpendicularly to its flat “racetrack” diaphragm - an ingenious architecture that 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. This article was originally published in Voice Coil, January 2021

Looking forward to serving the loudspeaker industry for another year, Voice Coil starts strong with a focus on Headphone OEM Devices and Parts, and a Spotlight article on speaker design, written by Brian Cho, the CEO of Resonado Labs. In his first Acoustic Patents column for 2021, James Croft writes about a signal processing system, allowing users to control a lower frequency acoustic range of a loudspeaker system, and Vance Dickason kicks off his Test Bench characterizations with the new Bold North Audio BWX-6502 Midbass, and the Wavecor TW022WA09 22mm textile dome tweeter.
