HELIX Ci3 T20FM-AL MK2
HELIX COMPOSE. The perfect speaker for any composition.
Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies paired with smart, practical engineering - the best of both worlds in harmony: high efficiency, fantastic sound quality and enormous dynamics that fit in any vehicle. HELIX COMPOSE - universal speakers evolved.
- 0.75” / 20 mm performance tweeter with black aluminum dome for accurate, pure and detailed treble response
- High-quality aluminum dome with perfect balance of low weight and high rigidity – for natural brilliance and fine detail reproduction
- Refined highly efficient neodymium magnet for high magnetic flux linearity and optimized performance
- Compact design and various mounting options for numerous installation demands
- Mounting pods for flush mount and angle mount included in delivery
- Designed for the optionally available car-specific FlexMount20 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
Price-performance highlight
Our HELIX COMPOSE i3 series is an absolute price-performance highlight, providing a first-class sound experience thanks to high-quality components and smart engineering. As you already know from our i7 series, our new mechanical technologies with unbeatable practical benefits, are implemented here as well. All speaker impedances are perfectly matched for the combination with our HELIX and MATCH amplifiers, guaranteeing maximum performance at any time.
Natural brilliance and precise detail resolution
The new Ci3 tweeter features an elegant black aluminum dome that strikes the perfect balance between low weight and high rigidity. Combined with the refined, highly efficient neodymium magnet system, it delivers an even more precise, clear, and detailed high-frequency response. The result is natural brilliance with outstanding resolution and impressive dynamics – for an exceptional listening experience.
FlexMount20 – Universal meets car-specific
FlexMount is a mounting system based on specially developed adaptor rings, allowing the installation of COMPOSE FlexMount speakers in an almost infinite number of vehicles. Thus, the universal tweeter effortlessly becomes a vehicle-specific tweeter, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount20 adaptor ring.

FAQs
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
