These vehicle-specific adaptor rings transform a universal 6.5" / 165 mm HELIX COMPOSE midbass into a speaker that slots perfectly into the original mounting position of a BMW i4. Each ring is 3D-printed in-house using FDM technology, using a material engineered for automotive use that resists UV, oils, greases, and temperatures from -40°C to over +90°C. Gaskets are included to prevent acoustic short circuits and keep moisture out, while the torsion-resistant design makes installation straightforward.
