Product overview
8 inch / 200 mm high-end woofer with 3 Ω impedance, FlexMount technology, novel UHD paper cone, mounting ring & grille
Key features
- 8” / 200 mm high-end woofer which combines outstanding sound performance with versatile physical integration options
- High efficiency and 3 Ohms technology for maximized power output of the amplifier
- Ultra High Damping (UHD) crafted paper cone for outstanding impulse response and unmatched frequency response
- 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
- Large 1.46” / 37 mm voice coil ensures minimum thermal compression and 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
- Automotive grade ProConnect connection terminal allows the use of conventional speaker cables or a fast, secure and fail-safe connection via optionally available WireKits
- Powerful magnet system for highest efficiency and extremely low distortion
- Universal mounting ring with grille included in delivery
- Designed for the optionally available car-specific FlexMount200 adaptors which allow an acoustically optimized and professional integration in the original mounting location of the vehicle
- Designed for optionally available, car-specific WireKits which allow a non-destructive integration
- Made in Germany
