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.
