SoundGarage - Hi-Res Audio


What is Hi-Res Audio?

With Hi-Res Audio streaming services and music downloads available, you can now appreciate a higher sampling rate than in CDs for the playback of music, which brings your favourite music tracks to life with extreme clarity. Alpine’s Hi-Res Audio Certified Head Units, Amplifiers and Digital Signal Processors are painstakingly engineered to deliver faithful audio reproduction from high-resolution sources and recordings with sample rates up to 192kHz/24Bit. These components are optimised for high-definition playback and breathtaking performance, true to the artist's original recording.

Why Hi-Res Audio?

Listening to Hi-Resolution Audio allows you to feel every emotion and hear every nuance; every detail of your favourite artist’s original studio performance is reproduced to perfection. Hi-Res Audio provides absolutely no distortion for the ultimate listening experience.

Why Hi-Res Audio Certified Speakers?

Hi-Res Audio goes beyond the limits of ordinary speakers. To accurately render the sound of Hi-Resolution sound sources and recordings in true high definition the reproduction of an extended dynamic frequency range right up to 40kHz is paramount.

Hi-Res Audio Certified

All-New for Alpine S-Series, Hi-Res Audio Certification brings a whole new dimension of sonic excellence to your everyday drive. Your recordings will come alive with a degree of clarity and delicacy authentic to the original recording, thanks to an astonishing expanded dynamic range that plays higher harmonics all the way up to 40kHz.

Alpine S2-Series Tweeters

Versatile Tweeter Installation

The 1” 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 axis sweet spot. For stealth applications, the frames can be removed to reduce down to a fraction of their original size to suit any installation and easy replacement of factory-fitted OEM tweeters.

Alpine S2-S65C Glass Fibre Composite Cone


Glass Fiber Composite Woofer Cone

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

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. Its ability to far exceed the maximum linear excursion of regular domed surround allows for beautifully pure sound and punchy bass.

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 a louder, punchier sound.
