Hi-Res Audio Certified Hard Dome Tweeter

They play right up to 40kHz allowing harmonics to reveal the finest of nuances for an authentic sound experience, faithfully to the original recording.

Direct Fit Installation

All speakers interface directly to the OEM, providing a quick and easy ‘plug-n-play’ connection. This means there is no need to cut, solder or modify any of the vehicle’s original wiring — saving you time by easily utilising the original speaker wires, allowing for a straight and simple installation.

Larger Magnet Structure

The new R-Series speakers feature a larger magnet structure for incredible bass. Despite this, the driver depth is unchanged from the previous generation to retain installation versatility, but with improved performance.

Glass-Fibre Reinforced Cone

The high-performance midrange and woofer drivers feature an all-new glass-fibre reinforced cone. This material is extremely rigid and light-weight, resulting in exceptionally fast cone velocity and response time, delivering highly accurate music reproduction.

Exclusive HAMR Surround

Alpine’s High Amplitude Multi-Roll (HAMR) surround provides a greater maximum and linear cone excursion for high SPL. The HAMR surround maintains full control over the cone at any excursion stage for powerful bass and pure sound.

High-Pass X-Over Network

This small X-Over networks are very easy to install – in may cases you can keep the original wiring in the vehicle’s doors by simply putting this network in, saving lots of time during installation. You can adjust the tweeter level by -3dB / 0dB / +3dB.
