Get It in Motion with Voice Coil August 2025

In this issue, Jonathan Gerbet explains everything we need to know about the next-generation of Klippel's Fast Large Signal Identification (FLSI) measurement tool. And as scheduled, Mike Klasco prepared a valuable directory of Voice Coil Winders, plus a subdirectory with Converters, Lead Out Wire, and Magnetic Fluid suppliers. For this month's Test Bench, Vance Dickason characterizes the new 10NTLW2500 Pro Sound Tetracoil midbass woofer from Eighteen Sound, followed by the UMII12-22 subwoofer from Dayton Audio's new Ultimax II line.

August is traditionally the voice-coil-focused issue of Voice Coil, offering an always-valuable perspective on the state of the loudspeaker industry. In this issue, Mike Klasco discusses Audio Manufacturing in The Philippines, James Croft explores another key Mayht patent, and Vance Dickason measures and characterizes the B&C Speakers DE111-8 1" compression driver, and the MD60N-6 2.5” Dome Midrange from SB Acoustics' Satori line.
