Ideas for Speaker Enclosures Now in Voice Coil March 2024

Voice Coil March 2024 focuses on speaker enclosures with a unique directory of innovative material ideas, followed by an always insightful patent review, where James Croft revisits the pivotal Dinaburg invention. For Test Bench, this month Vance Dickason characterizes the SIG180-4 6.5” woofer from Dayton Audio’s Signature Series, and a midbass shallow-profile 6.5” driver, the Stereo Integrity TM65 mkIV.

Founded in 2001, Stereo Integrity is an OEM speaker driver manufacturer from North Carolina that also designs its own range of hi-fi amplifiers, sold directly to consumers online. The company sent its M25 mkII high-end tweeter, which features a 25mm silk dome diaphragm and surround, a dual-magnet neodymium motor, a black anodized aluminum motor housing with a tuned rear chamber, two-layer CCAW wound voice coil, and a compact 50mm diameter face plate with a steel anodized grill.
