Description
HELIX Ci5 S200FM-D2 – Hybrid Mid-Woofer with Dual Voice Coils
The HELIX Ci5 S200FM-D2 from the COMPOSE series is designed for car audio enthusiasts who seek both high performance and installation flexibility. This 200 mm hybrid speaker merges the clarity of a mid-woofer with the deep output of a subwoofer, providing a precise and powerful listening experience in any vehicle. Its compact 47 mm installation depth allows integration in tight spaces, such as under-seat BMW or Mercedes bulkhead applications, without sacrificing sound quality.
Key Features and Advantages:
-
Hybrid performance: Delivers the midrange precision of a woofer combined with subwoofer-level bass control.
-
High excursion capability: ±7.5 mm linear excursion ensures accurate low-frequency output even at high volumes.
-
Compact design: Extremely low installation depth for easy integration in constrained vehicle spaces.
-
Dual 2 Ω configuration (D2): Ideal for multi-amplifier setups, providing maximum flexibility in mono, 2-channel, or multi-channel systems.
-
Robust basket construction: Made of a high-tech polymer composite reinforced with glass spheres for minimal resonance, thermal resistance, and compact dimensions.
-
FlexMount200 compatibility: Special adaptor rings allow universal speakers to fit acoustically optimized in a wide range of vehicles.
-
High efficiency: Optimized for powerful output and dynamic response with HELIX and MATCH amplifiers.
-
Non-destructive connectivity: Compatible with HELIX WireKits for fast, secure, and safe installation.
The Ci5 S200FM-D2 is engineered for audiophiles who want the best of both worlds—a hybrid speaker that provides exceptional midrange clarity and powerful bass, while maintaining flexibility for professional installation.
