MSC, the North American distributor for Brax, Helix, and Match, is preparing to ship a new Helix 6.5-inch midbass speaker in its Compose series. Compose speakers can act as a universal fitment or they can be used with vehicle specific Flexmounts.
Flexmounts are available for vehicles ranging from Lamborghini to Ford.
The new Ci5 W165FM-S3 is designed as a high excursion and high output driver that adds to the Compose i5 series (joining a 25 mm tweeter and 8 inch midbass). Early in the 4th quarter, a 50mm wideband driver and 80mm midrange will be added to round out the series.
These new midbass speakers are expected to ship at the end of August with a retail price of $500.
Features of the Helix Ci5 W165FM-S3
- 6.5” / 165 mm advanced midbass with “exceptional sound performance and versatile physical integration options”
- High efficiency technology with 3 Ohm impedance, maximizing the power output of the amplifier
- Silicon coated paper cone for impulse response and frequency response
- Integrated phase plug for improved upper midrange reproduction, reduced compression effects, and increased thermal power handling of the voice coil
- Engineered for maximum flexibility – delivers depth and dynamics in both 2-way and 3-way system configurations
- High-tech polymer composite basket reinforced with glass beads for rigidity and minimized ringing
- Specially shaped rubber surround for high linear excursion
- Large 1.46” / 37 mm voice coil ensures minimum thermal compression and high power handling
- 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
- Designed for the optionally available car-specific FlexMount165 adaptors optimized for the original mounting location of the vehicle
- Designed for optionally available, car-specific WireKits which allow non-destructive integration








Awesome addition to a great lineup. Highly looking forward to the wideband driver coming later this year!
