2022 R-Series Component and Coaxial Speakers
If you play music loud, the R-Series speakers are built for you. Tuned with an emphasis on high- and low-end frequencies, they deliver power and clear, distortion-free sound at high volumes. They are a natural pairing with R-Series subwoofers and amplifiers.
The 2022 R-Series line-up is fully Hi-Res Audio certified with a frequency response up to 40kHz. This generation introduces a 3-way system for the first time, with both Professional and Standard speaker options to suit different budgets and sound quality requirements. If you are looking for a 2-way option, Alpine also offer the S2-S65 6.5-inch 2-way coaxial speakers from the S2 Series.
3-Way Component PRO Speaker
The R2-S653 is the flagship model of the 2022 R-Series speaker range. It features a 16.5cm door woofer, 9.6cm mid-range and a 4.3cm tweeter with a 40kHz frequency response.
Glass-Fibre Reinforced Cone
The door woofer uses an all-new glass-fibre reinforced cone. The material is stiff yet extremely lightweight, delivering fast response and accurate music reproduction.
Die-Cast Aluminium Basket and Large Magnets
The PRO models feature high-quality die-cast aluminium baskets for increased stiffness, allowing larger magnets than previous generations without increasing mounting depth.
Hi-Res Audio Certified Hard Dome Tweeter
The magnesium hard-dome tweeters reproduce music up to 40kHz. They can be flush-mounted in their threaded housing or fitted using the included on-dash mounts, and can be swivelled to aim at the listening position.
Easy-Fit Tweeter in OEM Locations
Removing the installation frame and trim ring reduces the tweeter's overall diameter enough to fit in many OEM locations, including A-pillars, mirror triangles and door panels, for a clean, stealthy installation.
Flexible PRO X-Over Network
The large-format crossover network uses high-quality components throughout. Mid-range and tweeter levels are each independently adjustable at -3dB, 0dB or +3dB to suit your listening preferences.
HAMR Surround
Alpine's HAMR Surround (High-Amplitude Multi-Roll) maximises cone excursion while maintaining control, delivering strong bass at high volumes without distortion.
New Speaker Grilles
The included grilles feature a hexagon design and do not increase the overall installation diameter of the speaker.

About the Alpine R2-S653
From our tech experts at CEN
A 6.5 inch three-way component set, with separate tweeter, midrange and woofer. Component sets sound better because the tweeter can be aimed towards your ears rather than firing into your knees.
Who it suits
Drivers who want the best result from a door upgrade and are happy for tweeters to be mounted separately, which usually means a professional fit. They will run from a decent head unit, though an amplifier brings out more of them.
Our tech experts advise
Speaker sizes, adapter rings and harnesses vary by vehicle, year and trim, so we check what your car takes before ordering rather than guessing. Door treatment matters as much as the speaker. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs and what the work involves. See car audio installation.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Is the Alpine R2-S653 a 3-way speaker set?
A: Yes. Each side has a 16.5cm door woofer, a 9.6cm mid-range and a 4.3cm magnesium hard-dome tweeter, controlled by the PRO X-Over network.
Q: What mounting depth and cutout do the R2-S653 drivers need?
A: The woofers need 6.3cm depth and a 13.5cm cutout. The mid-ranges need 3.6cm depth and a 7.3cm cutout.
Q: Can I adjust the mid-range and tweeter levels on the R2-S653?
A: Yes. The PRO X-Over network lets you set the mid-range and tweeter levels to -3dB, 0dB or +3dB.
