Helix Ci3 W200FM-S2
Ci3 W200FM-S2
8" 2 Ohm woofer set
Features
- 8” / 200 mm performance woofer which combines outstanding sound quality with versatile physical integration options
- High efficiency and 2 Ohms technology for maximum power output of the amplifier
- Unique Cenosphere coated paper cone for precise and detailed sound reproduction
- High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing
- Specially shaped rubber surround for high linear cone excursion
- Polyurethane dustcap for optimized frequency response in the upper midrange area
- 1” / 25 mm voice coil ensures high power handling
- Compact dimensions with maximum performance - despite the small outer diameter, this woofer comes with the same cone area known from typical 200 mm chassis
