HELIX S 42C.2
Highest sound quality
With the S-series loudspeakers each ride becomes a special sound experience. The sophisticated design and the use of the latest technologies guarantee excellent sound characteristics with rich bass, accurate mids and crystal-clear highs.
Features
- 4” / 100 mm woofer with novel basalt-fiber-paper compound cone – a perfect combination of lowest weight, high stiffness and inner damping
- 1” / 25 mm silk dome tweeter in a noble aluminum housing for balanced, natural sound reproduction and lowest compression effects
- Individual HELIX basket with additional ventilation holes for better voice coil cooling and high power handling
- “Flex-Crossover“ with 12/12 dB slope, bandstop filter and three-stage tweeter level adjustment – separable and therefore well suited for the installation in vehicles with separate mounting positions of the tweeter and woofer
- Crossovers solely equipped with high grade components e.g. low-distortion air-core coils and minimum-loss Audiotec-foil capacitors for tweeter crossover
Classy design
In addition to the excellent sound characteristics, the S 42C.2 also impresses with its timeless elegant design. Especially the transparent "Flex-Crossover" with its high-quality components and the noble aluminum housing of the tweeter make this system a real feast for the eyes.
Easy integration
The sophisticated design with low installation depths, a removable housing of the tweeter and the very compact and innovative "Flex-Crossover" offer much more freedom in terms of connectivity and installation – even in particularly limited space. Additionally, it provides an easy cabling, thanks to Plug & Play connections between the individual components.
Maximum flexibility – “Flex-Crossover”
The new "Flex-Crossover" is not only a visual highlight, it also involves a couple of technical refinements. To drastically reduce the dimensions, the circuit board can also be installed without its housing in a supplied foam and it can be split into two parts for separate installation (e.g. tweeter in A-pillar, woofer in the door). In addition to a 3-stage tweeter level adjustment and Plug & Play cable connections, the crossover is also equipped with screw terminals for even more flexibility when connecting with your own speaker cables.

Helix
About the Helix S722421
From our tech experts at CEN
4 inch component speakers, with separate tweeters that can be mounted higher where you will actually hear them, rated at 70w RMS.
Who it suits
Drivers building a proper front stage. Helix is a brand people choose when they care about staging and detail rather than volume, and these reward an amplifier and a processor.
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.
