Experience the rich detail and sonic excellence of Alpine’s next-generation S-Series loudspeakers — now featuring Hi-Res Audio for the first time.

The S-Series continues to establish the benchmark in sound quality and value by producing impressively detailed loudspeakers that accurately represent true studio-level Hi-Resolution audio faithful across the entire frequency bandwidth.

Alpine innovation continues with all-new technology and engineering in the construction and materials adopted in the new S-Series.  The exclusive design composite glass fiber hybrid cone is extremely rigid and lightweight, which further unites with Alpine’s patented HAMR surround to achieve increased control and excursion of the woofer diaphragm, resulting in pure, punchy sound and powerful bass at high SPL.

In addition, the 1” soft dome tweeters come alive in the upper harmonics, delivering an incredibly smooth and detailed high frequency response that’s extended right up to 40kHz — so you can hear the finest nuances in your music.

With an extensive range of component and coaxial speakers, the new S-Series is the most impressive and versatile speaker line-up ever, providing system configuration flexibility and installation compatibility into virtually any vehicle type.

Take your in-car sound to the next-level with the new S-Series loudspeakers rivalling performance far beyond their modest price-point.

Hi-Res Audio Certified

All-New for S-Series, Hi-Res Audio Certification brings a whole new dimension of sonic excellence to your everyday drive. With an impressive extended dynamic range, playing upper harmonics all the way up to 40kHz, your tracks will come alive with a level of detail and nuance faithful to that of the original recording.

HAMR Surround

Not only does Alpine’s patented High Amplitude Multi-Roll (HAMR) surround maintain full control over the cone at any stage of excursion for high SPL. It’s ability to far exceed the maximum linear excursion of regular domed surround allows for beautifully pure sound and punchy bass.

Glass Fiber Composite Woofer Cone

The door woofer features an all-new glass fiber composite cone, which due to its directionally weaved construction is engineered to be far stronger than a traditional oval cone diaphragm. The resulting rigidity coupled to glass-fiber’s innate lightness results in highly controlled cone excursion producing excellent response and audio reproduction. 

Versatile Tweeter Installation

The 20mm Soft Dome Tweeters cater to a wide-array of installation methods. They can be flush mounted and swivelled within the housing to find the exact audio sweet spot. Or for stealth applications can reduce down to a fraction of their original size by removing the installation frame and trim ring for installations into OEM locations such as inside A-pillars, mirror triangles or door panels. 

Large Magnet Structure

The large strontium magnets housed on the back of S-Series speakers mean business. Combined with large voice coils and Alpine’s patented HAMR Surrounds, increase cone excursion and the force of the driver to provide louder, punchier sound.

Compact Footprint

S-S40C compact footprint makes it perfect for a myriad of installation options. From stealth speaker replacements to fit behind an OEM grille, to being proudly displayed within a custom A-pillar or dash housing, the choices are almost limitless.
