The Alpine R-Series Sound Components
The R-Series line-up is “The Loudest Family on the Block”. The products are designed to be played loud, delivering a fun and exciting listening experience and are known for dependable performance and high-quality sound. All R-Series components are developed to perfectly match each other.
The High Amplitude Multi-Roll (HAMR) surround allows a maximum, linear cone excursion for high SPL, while maintaining full control over the diaphragm at any excursion stage for high sound clarity.
Re-Engineered For Highest Performance
More power: the 2nd generation of R-Series speakers include many improvements over the 1st generation, such as the increased voice coil diameter from 30 to 35mm, while the Neodymium magnet diameter was also enlarged. This results in a stronger motor structure with a more powerful bass output.
CFRP (Carbon Fiber Reinforced Polymer) is a very lightweight yet rigid material. On a standard, off-the-shelf speaker cone, the edges are naturally weaker than the center due to the elongated shape. Since the CFRP material is directional, it can be manipulated during the molding process to strengthen the areas of the cone that are normally weak. The result is rigidity throughout the cone that delivers accurate and efficient performance.
Hi-Res Audio Tweeters
The 2nd generation R-Series tweeters feature Hi-Res Audio capabilities with a frequency response of higher than 40kHz. The tweeter cones are constructed by CFRP, allowing them to reproduce very high frequencies of over 40kHz, while maintaining an overall soft and smooth tonal balance of a soft dome tweeter.
The new voice coil is made of Aluminium, compared to regular copper wire coils. We increased the voice-coil diameter from 30mm to 35mm in the 2nd generation R-Series: the benefit is higher clarity especially in the mid-high frequency area and a more powerful bass reproduction.
Wave Guide Focuses the Sound
Alpine has developed a Wave Guide for the cone to further improve sound quality. Molded into the speaker cone, it prevents phase distortion of the sound waves from the diaphragm, and focuses the sound for optimum clarity.
Included Mesh Grill
We included a metal mesh grill to protect the woofer in open installations.
The included installation adapters allow easy installation in a wide range of vehicles and door speaker mounts. It also includes a 6 x 8” adapter.
Easy To Install Network
The external network is very compact and easy to install. Simply slide open the cover to gain access to the tweeter level adjustment (+3dB / 0dB / -3dB). This ensures a perfect balance between woofer and tweeter level in your car.
Both component and coaxial models feature a ring tweeter that swivels to improve off-axis response in less-than-ideal locations. You can aim it by hand for best imaging and staging at your listening position. The component type tweeter can be installed in flush-mount or on-dash configuration – all installation adapters are included.
