S-Series 10cm (4”) Coaxial 2-Way Speakers

S2-S40

Newly redesigned and Hi-Res Audio Certified, the Next-Generation S-Series S2-S40 10cm (4”) Coaxial Speakers offer a new standard in entry-level sound performance.

We packed supreme capability into these speakers by using highly effective materials and proprietary design elements. The lightweight woofer cone, crafted from a combination of polypropylene, glass fiber, and mica materials, serves up the essential high output / low distortion sound required for High-Res Audio performance. Alpine S-Series speakers feature increased magnet sizes for more power handling and best mid-bass performance in their category.

The woofer's High Amplitude Multi-Roll (HAMR) surround brings out the best in bass by allowing maximum cone movement. A 2cm (3/4") dome tweeter serves up all the high-frequency detail you've been missing with your factory speakers.

All speakers in the S-Series line have a wide vehicle fitment range and include several adapters and spacers. Using in-line crossovers, these speakers can be installed quick and easy even at home.

Hi-Res Audio Certified

Using “trickle-down” technology, inspired design, and performance cues from the Ultra-High-Resolution AlpineF#1Status system, the Next-Generation Alpine S-Series Speakers are now Hi-Res Audio Certified and able to reproduce up to 40kHz frequency response. This new benchmark in sound quality elevates the Next-Gen S-Series Speakers resulting in a more accurate and natural sound at an entry-level price point.

Clean, Accurate Audio

Crafted with a unique combination of Poly Propylene, Glass-Fiber, and Mica Cone materials, the S2-S40 is designed for lightweight construction, high output, and low distortion, giving you a clean and accurate audio experience.

HAMR Surround

Alpine-exclusive High Amplitude Multi-Roll (HAMR) surround technology is integrated into the speaker design which allows for maximum cone movement, delivering powerful and accurate bass notes.

Extensive Mounting Options

The S-Series S2-S40 is compatible with most 10cm installation locations in various vehicles. The steel basket features several screw brackets for different mounting applications.

Made for S-Series Amps & Subs

The S-Series speakers are designed to perfectly match the Alpine S-Series amplifier and subwoofer line for perfect system building. S-Series components are designed to for customers that want to build a great sounding system without breaking the bank, for a fun and great sounding experience including Hi-Res Audio capabilities.

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.
