  • Dust cap is ultra stiff, helping cast a precise performance

Build and heat management

Key features include a vented T yoke, a 10 mm yoke plus an additional tension washer for robust magnet control, and high temp bonding materials. These elements work together to withstand demanding listening sessions.

Installation and enclosure options

Designed for easy integration, it ships with a dedicated mounting gasket and specifies a 7.32 inch cutout and 5.91 inch mounting depth. Recommended enclosure volumes cover sealed and vented configurations to suit your space.
