Innovative Speaker Drivers and Microspeakers in Voice Coil May 2022

In this month’s Voice Coil Focus, Mike Klasco writes about Innovative Speaker Drivers, and there is an updated Microspeaker Vendor Directory for 2022, with additional subdirectories on MEMS speaker transducers and Haptic Actuator devices for mobile devices. On this month’s Test Bench, Vance Dickason characterizes two full-range woofers: the E180HE-44 from the Dayton Audio Epique home audio line-up, and the Faital Pro 2FE24 2.5” small woofer targeting pro audio applications.

This Test Bench explication focuses on the Dayton Audio Epique MMAG E150HE-44 "full-range subwoofer," in itself an interesting concept. Like its larger E180HE-44 brother in the Epique line, the E150HE-44 is based on the patented Multiple Magnet Air Gap (MMAG) technology invented by Enrique Stiles. The two new Dayton Audio Epique MMAG woofers were designed with direct support by Enrique as an independent transducer engineering consultant, working in conjunction with the engineering team at Dayton Audio. This article was originally published in Voice Coil, December 2021.

In the December 2021 edition of Voice Coil, Vance Dickason details the possibilities of the CrossLite+ DSP filter software, while James Croft reviews an interesting invention to improve the bass response in automotive audio applications. And this edition includes an updated measurement microphone directory, and two interesting low-frequency drivers on Test Bench, with the Dayton Audio Epique MMAG E150HE-44 subwoofer, and the powerful 10NW76 high-SPL woofer from B&C Speakers.
