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 fibre 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.
KTE-S50G Grilles pictured are sold separately.
Key Features:
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 directional 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.
Integrated Hi-Resolution Soft Dome Tweeter
- The integrated 2omm Soft Dome Tweeters allow your music to come alive! Playing upper harmonics climbing all the way to 40kHz, these beautifully soft yet remarkably detailed tweeters are Hi-Res Audio Certified, bringing the studio to the dashboard with a level of nuance and authenticity not possible with traditional speakers.
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.
