Every component has been optimized to deliver uncompromising sound quality, exceptional dynamics, and long-term reliability.

UHD Paper Cone Technology

At the heart of the Ci7 W130-S3 is HELIX’s exclusive Ultra High Damping (UHD) handcrafted paper cone. Manufactured using a complex production process, the cone combines extremely low resonance with outstanding impulse response, allowing music to be reproduced with exceptional speed, precision, and natural tonal balance.

The result is tight, controlled mid-bass and remarkably realistic vocal reproduction.

High Efficiency and Low Distortion

Thanks to HELIX’s 3 Ω technology, the speaker extracts more usable power from compatible amplifiers while maintaining excellent efficiency and higher sound pressure levels.

The high-tech polymer composite basket, reinforced with glass beads, minimizes unwanted resonance while remaining lightweight and extremely rigid. Combined with a powerful magnet system and optimized rubber surround, the Ci7 W130-S3 delivers clean, distortion-free performance even at high listening volumes.

Easy Integration with ProConnect

HELIX’s innovative ProConnect terminal provides a secure automotive-grade connection that supports both conventional speaker cables and optional HELIX WireKits for true plug-and-play installation in many vehicles.

This allows for professional, reliable installation without modifying the factory wiring harness.
