Ci7 W200FM-S3

Helix "Compose" 8" midbass woofers

8” / 200 mm high-end woofer which combines outstanding sound performance with versatile physical integration options
High efficiency and 3 Ohms technology for maximised 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 minimised ringing
Specially shaped rubber surround for high linear cone excursion
Polyurethane dust cap for optimised 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
