Alpine R2-S65 R-Series 6.5" (16.5cm) 2-Way Coaxial Car Speakers | 300W

The Alpine R2-S65 6.5″ coaxial speakers are engineered to deliver exceptional audio performance in car stereo systems — providing powerful mid-bass, smooth mid-range and crisp high-frequency output. As part of Alpine’s premium R-Series, these speakers utilise glass-fibre reinforced cones for strength and accurate sound reproduction with minimal distortion. The magnesium hard-dome tweeter delivers clear, detailed treble while maintaining overall tonal balance. Certified for Hi-Res Audio up to 40 kHz, the R2-S65 reproduces extended frequency content with refined detail and clarity, elevating your listening experience above standard OEM speakers.

Alpine’s High-Amplitude Multi-Roll (HAMR) surround technology allows greater cone excursion for deeper bass response while preserving responsiveness and control — even at higher volume levels. Designed for broad compatibility with both factory car stereos and aftermarket head units, the R2-S65 speakers offer efficient performance that doesn’t require complex installation. With rugged construction and reliable performance, these speakers are ideal for drivers and installers seeking a significant audio upgrade that’s still easy to fit.

Whether you’re replacing worn factory speakers or building a high-performance car audio system, the Alpine R2-S65 provides dynamic sound quality, enhanced musical detail and a satisfying listening experience on every journey.

R2-S65 Key Features

The New 2022 R-Series Speakers

Alpine's Legendary R-Series Speakers enter the 3rd generation and are designed with innovative materials to deliver more output and sound simply amazing. You can choose between a professional and standard speaker line to fit your desired sound quality and budget.

2-Way Coaxial Speaker

The R2-S65 is the 2-Way Coax model of the new 2022 R-Series speaker line-up. It features a 16,5cm door woofer as well as an integrated tweeter with up to 40kHz frequency response.

Glass-Fiber Reinforced Cone

The door woofer features an all-new glass-fiber reinforced cone. This material is very stiff and extremely light-weight, resulting in a super-fast response and highly accurate music reproduction.

Composite Basket and Large Magnets

The standard models (R2-S65, R2-S65, R2-S69C and R2-S69) feature composite baskets (in comparison to the Aluminum die-cast baskets of the PRO models) – which makes them more affordable. They fit larger magnets than in previous generations (while maintaining the same mounting depth).

Hi-Res Audio Certified Hard Dome Tweeter

The all-new magnesium hard-dome tweeters deliver clear, detailed music reproduction and play up to 40kHz (Hi-Res Audio). The Coax-tweeters can be swiveled in their housing to point them right at the sweet-spot.

HAMR Surround

Alpine’s HAMR Surround (High-Amplitude Multi-Roll) allows for a maximum cone excursion, while maintaining excellent control. This results in strong bass at high volumes without distortion.

New Speaker Grilles

The new speakers grilles in hexagon design look very aggressive and do not increase the overall speaker installation diameter.
