i5 Series - The Perfect Connecting Link
Helix's i5 series is designed to be the connecting link between the i7 and i3 series'. Created for sophisticated music lovers with a sparked ambition for a true high-fidelity experience; the i5 range is the result of the successful marrying up of phenomenal sound with unmatched practicality. Like their brethren, Helix's i5 speakers are completely compatible with all Compose mechanical interfacing technologies such as the FlexMount and WireKits concepts. All in all, the i5 represent absolute value for money; proving that aural superiority is not beyond reach for the fiscally mortal sound enthusiast.

Design Ideologies
The Compose range was conceived due to the increasingly demanding challenges of modern automobile technology, not to mention Helix’s unending pursuit of intelligent solutions. Helix took its universal speaker ranges and undertook an extensive redesign. The result is this innovative series, which aptly stands by the motto developed inside the vehicle, for the vehicle. The various Compose series’ combine classic universal speakers with the advantages of vehicle-specific systems by marrying innovative materials and the latest technologies with smart, practical engineering solutions. The interlink of the Compose stable are the i5 range of components. They represent the perfect connection between the i3 and the i7 series. They represent tremendous value for money, high efficiency, fantastic sound quality and enormous dynamics.

The Sound Sensation For Sophisticated Music Lovers
The i5 were developed to embody phenomenal sound and unmatched practicality, with the vision of unique speaker highlights that are also true problem solvers. All speakers impedances are perfectly matched for modern day OEM and aftermarket amplifiers, guaranteeing maximum performance at any time. In addition to this, Helix engineers have implemented the Compose range exclusive mechanical technologies that offer unbeatable practical benefits. 

Precise Midrange Performance
The Ci5 M80FM-S3 has been engineered as an audiophile midrange driver designed to deliver exceptionally accurate midband reproduction in high-quality three-way systems. Its wide usable frequency range, high power handling and generous linear excursion make it ideal for applications where clarity, natural tonality and dynamics are essential.

Thanks to its significantly reduced outer diameter compared with conventional drivers of this size, along with the FlexMount technology; these speakers offer outstanding integration flexibility; even in tight OEM openings and without compromising the cone area size. This makes them perfectly suited for demanding multi-way systems, DSP-optimised setups or vehicles where precise midrange reproduction and a compact form factor are equally important.

Sophisticated Engineering For Dynamics, Efficiency And Low Distortion
The remarkable performance of these drivers are the result of a carefully coordinated combination of materials and mechanical design. Its silicon-coated paper cone provides high internal damping, an exceptionally natural and accurate midrange reproduction and suppresses unwanted resonance frequencies. The particularly narrow surround structure whose inward-folded surround edge is bonded in a complex manufacturing process. This works in conjunction with the innovative magnet system to allow for a large linear excursion, a key factor behind the driver’s high power handling and low-distortion behavior; ensuring confident performance even at elevated listening levels.

Furthermore, it noticeably reduces the outer diameter while increasing the effective cone area. The result is a compact form factor paired with high acoustic efficiency. Completing the design is an aluminum dust cap that enhances upper midrange performance, along with a powerful push-pull neodymium magnet system that combines high efficiency with minimal distortion. This contributed significantly to the precise, dynamic sonic character of these speakers.

High Efficiency
Helix compose equals smart engineering and accordingly implements highly efficient 3 Ohm technology, that perfectly harmonises with all Helix and Match amplifiers and at the same time allows a clearly perceptible plus in efficiency and maximum sound pressure.

High-Tech Polymer Basket
The speaker basket is made of a high-tech polymer composite, which has been additionally reinforced with glass spheres. The result is maximum stability with minimal self-resonance, while also eliminating flux modulation of the magnetic system and maximum resistance to thermal influences. Last but not least, this allows for much more compact basket dimensions and thus simplified installations in cramped installation conditions.

FlexMount – Universal Meets Car Specific
FlexMount is a mounting system based on specially developed adapter rings, allowing the installation of all Compose speakers into an almost infinite number of vehicles. Thus the universal loudspeaker effortlessly becomes a vehicle-specific loudspeaker, that can be easily installed in the original installation position of the vehicle in an acoustically optimized way with the matching FlexMount adapter ring.

WireKits – Plug And Play At Its Best
Helix WireKits allow the connection of all Compose components to the original wiring harness, or optionally to the crossover; in the most comfortable way. Manufactured according to the high standards of the automotive industry these arrestable adapter cables meet all requirements for the harsh environmental conditions that installers are facing in vehicles every day.
