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 CD’s 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 painstaking 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 artists 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 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.

Perfect Integration

Alpine’s premium design ‘A Pillar’ direct-fit tweeter housings are made from premium injection moulded PC/ABS polymer and feature an debossed Alpine logo complimented by black chrome and machined metal accents which are all pre-assembled components ready for direct installation to suit your BT-50.

Premium Design Tweeter Housing

Premium audio never looked so good. The bold, yet ornate design of the tweeter housing directly replaces the OEM which elevates the interior aesthetic and optimises the tweeter axis for superior sound quality.

Alpine Patented Technology for Superior Sound

These speakers adopt a 35mm voice coil and a precision neodymium magnet motor structure delivering extraordinary cone velocity for incredible linearity and powerful bass to get an exquisite listening and driving experience.

Glass Fiber Composite Woofer Cone

The 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  lightness results in highly controlled cone excursion producing excellent 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. It’s ability to far exceed the maximum linear excursion of regular domed surround allows for beautifully pure sound and punchy bass.
