Alpine R2-S652

R-SERIES PRO 2way Component Speakers

If you play your music loud and want others to know, the R-Series speakers are the match for you. You’ll enjoy a centre sound stage with speakers that play loud and clear without distortion.

The R-Series speakers are tuned with an emphasis on the high- and low-end frequencies, so they deliver power while naturally producing bright, active sound. They are the perfect power and performance match for the R-Series subwoofers and amplifiers.

The all-new 2022 line-up of R-Series speakers are all Hi-Res Audio certified and features a frequency response up to 40kHz. For the first time, the R-Series line includes a 3-way system and you can even choose from a Professional and Standard speaker line.


2-Way Component PRO Speaker

The R2-S652 is the top of the line 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.

Alpine R2-S653

Glass-Fiber Reinforced Cone

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

R-Series speakers are engineered to deliver prodigious power while maintaining extreme sound clarity for a totally exciting sound. They provide high power output and handling, wide frequency response, and powerful bass. The R-Series line includes component and coaxial speakers, subwoofers and for the first time, amplifiers.

Alpine R2-S653

Die-Cast Aluminum Basket and Large Magnets

The PRO models (R2-S635 and R2-S652) feature high-quality aluminium 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 swivelled 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.

New 2-Way PRO Component Speakers

The PRO versions feature rigid die-cast aluminium baskets for higher stiffness and build quality and are available in a 2-way (16.5cm woofer and 4.4cm tweeter) and 2-way configuration. The standard R-Series speakers feature composite baskets available in 2-way component and coaxial variations.

Flexible PRO X-Over Network

This large-size crossover network includes many high-quality components selected for the 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.

Professional Speaker Network

The all-new speaker networks are much larger than the 2nd generation R-Series, which include more and better components and many tuning options. This gives installers many possibilities to adjust the sound perfectly for your vehicle.

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 Grills

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

R-Series Technology

The 3rd generation of R-Series speakers features a more powerful motor structure (larger magnet size and 35mm voice coil) for increased SPL and bass output and less distortion. The new glass-fibre reinforced cone delivers warm, natural sound, while the HAMR surround ensures maximum cone excursion and control.
