ESB Audio 9.1T-28 Ring — 9.1T-28 CNC Mounting Ring (pair) | HF Audio
CNC-machined aluminum mounting ring for 9.1T-28 tweeter flush install.
Built for the Passionate. Engineered for the Road. The ESB 9.1T-28 CNC Mounting Ring is a precision-machined aluminum accessory designed for flush-mount installation of the 9.1T-28 tweeter. At the 9000 Series level, the quality of the mechanical installation matters — an imprecise mount introduces vibration paths that degrade the acoustic performance of even the finest tweeter. Machined from aluminum billet, the ring provides a rigid, resonance-free mounting surface with a precise fit tolerance matched to the 9.1T-28 tweeter housing. The flush-mount profile integrates cleanly into custom A-pillar pods, CNC-milled baffles, and precision fabricated door panels. Sold as a pair. Required accessory for any 9000 Series installation where aesthetics and mechanical precision are as important as acoustic performance — which, at this level, they always are.
