Helix Compose
The Helix Compose platform combines classic universal speakers with the advantages of vehicle-specific systems. Developed in response to the demands of modern automotive installations, it pairs innovative materials and smart engineering to deliver high efficiency, strong dynamics and excellent sound quality across a wide range of vehicles. If you need a 4 inch component option, the Helix Compose i3 Ci3 K100.2FM-S3 is also available.
The essentials for an exceptional sound experience
The Basic series is the entry point into Helix Compose. All components are designed to work together and integrate well with Helix and MATCH amplifiers for reliable performance and power output. The Basic tweeter also includes smart mechanical design features focused on safe, professional installation.
High efficiency
Helix Compose uses 3 ohm technology, which is compatible with all Helix and MATCH amplifiers and delivers a noticeable gain in efficiency and maximum sound pressure. Select models are also available as 2 ohm variants for maximum output when paired with a suitable amplifier.
Powerful bass, always on point
The Compose Basic bass-midrange driver uses a lightweight polypropylene diaphragm for strong sound performance, with a sturdy basket featuring additional ventilation holes for improved cooling. A powerful magnet system ensures accurate impulse response, and the soft polyurethane dustcap optimises frequency response in the upper midrange. The compact build makes it well suited to tight mounting locations.
High-frequency reproduction with unique dynamics
The Basic tweeter uses a coated silk dome and a highly efficient neodymium magnet, delivering dynamic high-frequency reproduction and clear, detailed sound.

Our tech experts advise
Sizes, adapter rings and harnesses vary by vehicle, year and trim, so we confirm what your car takes before ordering rather than guessing. Door treatment and tweeter placement change the result as much as the speaker does. Installation and tuning are priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
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.
Q: What size is the HELIX CB C100.2-S3?
A: It is a 4 inch (100 mm) 2-way coaxial speaker, sold as a pair.
Q: What impedance is the HELIX CB C100.2-S3 and will it work with my head unit?
A: It is a 3 ohm speaker. 3 ohm technology raises efficiency and maximum sound pressure, and it is matched to HELIX and MATCH amplifiers. It handles 60W RMS, so a dedicated amplifier lets it perform at its best.
Q: What tweeter does the CB C100.2-S3 use?
A: A 0.75 inch (20 mm) silk dome tweeter with a neodymium magnet, high-passed by an integrated 6 dB crossover.
