audioXpress has published the August 2026 edition of Voice Coil online. The issue concentrates on voice-coil production, with a profile of Poyun, an examination of coil design and manufacturing, and a tutorial on the SpeaD Spider Designer tool.
Test Bench sections evaluate the SB Audience ROSSO-25CDN-P compression driver, SEAS M64F001 midrange, and Celestion TSQ2460 24-inch subwoofer. The coverage goes beyond catalogue data to impedance, response, distortion, and Klippel-based measurements that expose design choices.
Wire, winding geometry, former material, adhesive, and heat removal sit out of sight in a completed loudspeaker, yet they determine power compression and reliability. Placing manufacturing coverage beside measurements of several new drivers makes the relationship between those decisions and electroacoustic performance easier to follow.
