All parts are pre-assembled with ‘plug-n-play’ connections providing a straightforward, no-fuss installation with no need for any modifications, cutting of wires, or soldering.

Perfect Integration

Alpine’s premium design ‘A Pillar’ direct-fit tweeter housing with machine cut Alpine logo and black chrome bezel which are all pre-assembled parts ready for direct installation to your BT-50.

Premium Design Tweeter Housing

Premium audio never looked so good. The bold, yet the 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.

Experience your music with remarkable Power and Authenticity

S-Series are engineered for amazing sound quality coupled with Alpine-specific audio tuning. They feature Alpine’s HAMR surround for high linearity and accuracy, plus a CFRP-patented cone technology reproducing exceptional clarity and bass dynamics.

Industry First CFRP Woofer Cone

The S-Series speakers set an industry first, utilising CFRP (Carbon Fibre Reinforced Plastic), a very lightweight yet rigid material. On an ordinary oval cone, the edges are naturally weaker than the centre due to the elongated shape.

Alpine HAMR Surround

Alpine’s patented H.A.M.R. (High Amplitude Multi-Roll) surround is now found on the S-Series speakers. This proven technology increases excursion while maintaining accuracy and linearity creating incredible linearity and colourisation rejection.

1-Year warranty as per Alpine Electronics Australia's terms and conditions
