Alpine R2-S652 R-Series 6.5" (16.5cm) 2-Way Component Car Speaker System | 300W

The Alpine R2-S652 R-Series Pro component speakers are engineered for car audio enthusiasts who demand powerful performance and precision sound reproduction. Built with glass-fibre reinforced cones and premium die-cast aluminium baskets, they deliver exceptional rigidity and low distortion while maintaining accurate, responsive playback across the full frequency range. Hi-Res Audio certification ensures detailed high-frequency response up to 40kHz, giving your music more depth, clarity and realism.

Designed to play loud while remaining clean and controlled, the speakers utilise Alpine’s High-Amplitude Multi-Roll (HAMR) surround for improved cone movement and stronger bass output. Magnesium hard-dome tweeters provide crisp highs, while premium passive crossover networks ensure precise sound separation and optimal system tuning.

Supplied as a matched pair with protective mesh grilles and full installation hardware, the R2-S652 component kit is ideal for upgrading factory car speakers or building a full Alpine R-Series performance system. Perfect for installers and enthusiasts alike, these speakers deliver the loud, dynamic and highly detailed sound signature that R-Series is known for.

R2-S652 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 Component PRO Speaker

The R2-S652 is the 2-Way PRO model of the new 2022 R-Series speaker line-up. It features a 16,5cm door woofer and a 4,3cm tweeter with up to 40kHz frequency response.

Glass-Fiber Reinforced Cone

The door woofer and the mid-range speaker feature all-new glass-fiber reinforced cones. This material is very stiff and extremely light-weight, resulting in a super-fast response and highly accurate music reproduction.

Die-Cast Aluminum Basket and Large Magnets

The PRO models (R2-S635 and R2-S652) feature high-quality aluminum baskets – resulting in high stiffness and can carry heavier magnets without warping. This allowed our engineers to 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). You have the option to flush-mount them in their threaded housing (for example in a door panel) or use the included on-dash mounts. The tweeters can be swiveled in their housing to point them right at the sweet-spot.

Easy-Fit Tweeter in OEM Locations

You can simply remove the installation frame and the trim ring of the R-Series tweeter to minimize its overall size and diameter. The tweeter itself is then small enough to fit it in many OEM tweeter locations (inside A-pillars, mirror triangles or door panels) for a stealthy installation.

Flexible PRO X-Over Network

This large-size crossover network includes many high-quality components selected for best sound quality. You can adjust the mid-range speaker level by -3dB / 0dB / +3dB and the tweeter level as well by -3dB / 0dB / +3dB.

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.
