Description
Ci5 S200FM-S2
Helix 2 Ohm slim 8″ woofer – pair
Features
- Exceptional cone excursion – ensures high sound pressure levels and impressive low-frequency reproduction
- Hybrid flat woofer concept – a perfect balance between a powerful subwoofer and a mid-woofer driver that covers a frequency range from 25 to 500 Hz
- Chassis with 1 x 2 Ohms single voice coil for maximum power output of the amplifier
- Minimum installation depth – an innovative basket design with only 47 mm installation depth for the use in restricted mounting spaces
- Compact dimensions with maximum performance – despite the small outer diameter, this woofer comes with the same cone area known from typical 200 mm chassis
- Lightweight polypropylene cone which provides essential stiffness for phenomenal sound performance
- High-tech polymer composite basket reinforced with glass beads for enormous rigidity and minimized ringing
- Powerful magnet system for high efficiency and optimum impulse response
- Perfect for difficult applications – e.g. can be installed under the seats in various BMW models or as front subwoofer in Mercedes cars
