Description

HELIX Ci5 S200FM-S2 – Hybrid Mid-Woofer Speaker

The HELIX Ci5 S200FM-S2 is part of the COMPOSE i5 series, designed for audiophiles seeking precise midrange performance and powerful low-frequency output in a compact design. This 200 mm hybrid speaker combines the clarity of a mid-woofer with the deep impact of a subwoofer, delivering dynamic sound even in tight installation spaces. Its slim 47 mm depth makes it ideal for under-seat BMW setups or Mercedes bulkhead applications.

Key Features:

• Hybrid Woofer Design: Combines midrange precision with subwoofer-level bass for balanced audio from 25 Hz to 500 Hz.

• Exceptional Excursion: ±7.8 mm linear excursion ensures clear, controlled low frequencies at high sound pressure levels.

• Compact Integration: Minimal installation depth allows fitting in constrained spaces without sacrificing cone area or performance.

• Durable Basket: High-tech polymer composite reinforced with glass spheres reduces resonance, provides thermal stability, and allows for simplified installation.

• Flexible Wiring Options: Available as 1 x 2 Ω (S2) or 2 x 2 Ω (D2) to suit various amplifier setups.

• FlexMount200 Technology: Special adaptor rings make it easy to integrate this universal speaker acoustically optimized in multiple vehicles.
