HELIX CB C87.2-S3 Compose Basic - 87mm 2-way coaxial system

The Helix CB C87.2-S3 series was born from the commitment to tackle the increasingly challenging demands of modern automotive technology, combined with HELIX's constant pursuit of intelligent solutions. This series represents the evolution of proven universal speaker systems, integrating innovative materials, cutting-edge technologies and intelligent engineering. The goal is to provide an exceptional sound experience inside the vehicle, combining the advantages of universal loudspeakers with those of vehicle-specific systems. All components are designed to work in harmony with HELIX and MATCH amplifiers, ensuring maximum performance and power.
High Efficiency
HELIX COMPOSE adopts a high-efficiency 3 Ohm technology. This technological choice integrates perfectly with HELIX and MATCH amplifiers, offering tangible advantages in terms of efficiency and maximum sound pressure. Some models are also available as optional 2 Ohm variants, optimizing performance in combination with compatible amplifiers.
COMPOSE Midrange Driver
The CB C87.2-S3 series features a COMPOSE midrange driver characterized by a lightweight yet stable polypropylene diaphragm, which delivers exceptional sound performance. The robust basket includes ventilation holes for optimal cooling. The powerful magnet system guarantees ideal impulse response, while the soft polyurethane dust cap optimizes frequency response in the upper midrange area. The compact design is ideal for installations in tight spaces.
PEI Dome Tweeter
For precise reproduction of high frequencies, the CB C87.2-S3 series uses a PEI dome tweeter and a high-efficiency neodymium magnet. The result is a unique dynamic in high-frequency reproduction and crystal-clear sound.
