The July 2026 issue of Voice Coil provides a comprehensive update on loudspeaker manufacturing, featuring a technical analysis of new drivers from SB Audience, REDCATT, and Dayton Audio, alongside an expanded directory of industrial adhesives and acoustic measurement hardware. The industry continues to emphasize precision, with new testing equipment from Z-Tech and Roga Instruments joining the global supply chain.
What are the latest developments in measurement microphones?
Vance Dickason reports that the global measurement microphone market is expanding, specifically noting two precision manufacturers that have recently entered the professional audio sphere. Z-Tech (Zhengtian Technology Co., Ltd.), founded in 2006, provides a broad range of microphones and acoustic accessories. Roga Instruments, established in 2004 and based in Nentershausen, Germany, specializes in vibration and acoustic test equipment. According to Dickason, these firms offer alternatives to established players currently listed in the Loudspeaker Industry Sourcebook.
How are manufacturers evolving driver design?
Recent Test Bench evaluations highlight three distinct approaches to transducer engineering, each focusing on different segments of the professional and home audio markets:
- SB Audience NERO-5CCN125D: A 5” pro midrange driver featuring a closed-back design with a cast-aluminum rear cavity filled with damping material. It utilizes a carbon fiber cone and a neodymium ring magnet motor.
- REDCATT 121XR-X8: An innovative 12” pro sound woofer that employs a radially charged neodymium magnet structure. A key feature is the “active” shorting ring—a secondary copper winding connected in parallel to the main voice coil to minimize modulation.
- Dayton Audio EC30MP-4: A 30mm ceramic dome tweeter designed for home audio. It features an aluminum faceplate, a copper-clad pole piece for impedance control, and a rated sensitivity of 92.5dB.
Why is the “gooey” supply chain critical for loudspeaker production?
Mike Klasco and the Menlo Scientific team have updated the industry directory for chemical and dispensing products essential to driver assembly. This resource covers adhesives, coatings, and sealants required for diaphragm damping and environmental protection. The directory highlights treatments that resist UV degradation, corrosion, and microbial growth, as well as hydrophobic and oleophobic coatings. These chemical solutions are critical for ensuring long-term performance in diverse acoustic environments.
Frequently Asked Questions
Where can industry professionals access the full Voice Coil directory?
Subscribers can access the digital version of the latest issue by logging into the platform at www.gotomyvcoil.com using their subscriber number and postal code.
What distinguishes the REDCATT 121XR-X8 motor design?
The driver utilizes a unique active shorting ring, which is a secondary winding inset into the inner gap area of the return cup, rather than a passive metal ring.
Is the NERO-5CCN125D designed for open-baffle use?
The driver features a closed-back design with a removable rear cavity, allowing users to either use the factory-provided cast-aluminum housing or integrate the driver into a custom back box.
