HiFonics ZSB8.3C

The HiFonics ZEUS ZSB8.3C is a high-quality, vehicle-specific 3-way component speaker system designed specifically for numerous BMW and MINI models. It combines powerful 20 cm under-seat subwoofers with precisely tuned 10 cm midrange drivers and 25 mm fabric-dome tweeters.

During development, special attention was paid to the high-performance neodymium magnet systems. Compared to conventional ferrite magnets, these enable a compact, weight-optimized design with high efficiency.

The two 20-cm subwoofers feature exceptionally sturdy glass-fiber cones and generously sized 50-mm voice coils. As a result, they deliver powerful, dynamic bass and complement the sound with a robust low-frequency foundation.

The 10-cm midrange drivers deliver precise reproduction of vocals and instruments, while the 25-mm fabric-dome neodymium tweeters ensure detailed and pleasant high-frequency reproduction.

Thanks to vehicle-specific plug-and-play connectors, compatible adapters, and the included installation accessories, the speakers can be retrofitted without requiring any major modifications to the vehicle's original wiring.
