Next-generation 6.5-inch 2-way R-Series component speakers

The R-Series speakers are built for loud, clean playback with a centred sound stage and no distortion. Tuned to emphasise high and low-end frequencies, they deliver power alongside bright, detailed sound. They are an ideal match for R-Series subwoofers and amplifiers. All 2022 R-Series speakers are Hi-Res Audio certified with frequency response up to 40kHz. The range now includes a 3-way system, with a choice of Professional and Standard speaker lines.

2-way component speaker

The R2-S65C is the 2-way model in the 2022 R-Series line-up. It pairs a 16.5cm door woofer with a 4.3cm tweeter delivering up to 40kHz frequency response. If you are looking for a coaxial alternative, the Alpine S2-S65 is a 6.5-inch 2-way coaxial from the S2-Series at 80W RMS.

Glass-fibre reinforced cone

The door woofer uses a glass-fibre reinforced cone — stiff and lightweight — for fast response and accurate music reproduction.

Composite basket and large magnets

The R2-S65C uses a composite basket (rather than the aluminium die-cast baskets found on the PRO models), keeping costs down while accommodating larger magnets than previous generations — without increasing mounting depth.

Hi-Res Audio certified hard-dome tweeter

The magnesium hard-dome tweeters reproduce clear, detailed sound up to 40kHz (Hi-Res Audio certified). They can be flush-mounted in their threaded housing or installed using the included on-dash mounts, and can be swivelled to point towards the listening position.

Easy-fit tweeter in OEM locations

Remove the installation frame and trim ring to reduce the tweeter to its minimum size and diameter. This allows it to fit many OEM tweeter locations — A-pillars, mirror triangles and door panels — for a discreet installation.

High-pass crossover network

The compact crossover networks are straightforward to install. In many vehicles you can retain the original door wiring and simply add the network in-line. Tweeter level is adjustable by -3dB / 0dB / +3dB.

HAMR surround

Alpine's HAMR Surround (High-Amplitude Multi-Roll) maximises cone excursion while keeping control, producing strong bass at high volumes without distortion.

New speaker grilles

The hexagon-design grilles give an aggressive appearance and do not increase the overall speaker installation diameter.

About the Alpine R2-S65C

From our tech experts at CEN

The Alpine R2-S65C is a 6.5-inch (16.5cm) 2-way component speaker set from Alpine's 2022 R-Series, rated at 100W RMS and 300W peak. It pairs a glass-fibre reinforced door woofer with a 4.3cm magnesium hard-dome tweeter, covering 65Hz to 40kHz and carrying Hi-Res Audio certification.

Who it suits

These suit drivers wanting precise stereo imaging, with tweeters that can be aimed towards the listening position and stripped down to fit many OEM locations such as A-pillars and mirror triangles. Those who want aluminium die-cast baskets and a three-way setup should consider the Alpine R2-S653.

Our tech experts advise

The woofer needs a 13.5cm cut-out and 6.3cm mounting depth — check your door cards before ordering. Crossover networks can often be wired in-line with existing door wiring, and tweeter level is adjustable at -3dB, 0dB or +3dB to suit your listening position. Fitting is priced per vehicle; see our Nottingham car audio installation page for details.

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: Can the R2-S65C tweeters be fitted in factory tweeter locations?

A: Yes. They can be flush-mounted in their threaded housing or used with the included on-dash mounts, and with the installation frame and trim ring removed the tweeter is small enough for many OEM locations such as A-pillars, mirror triangles or door panels.

Q: What mounting depth and cut-out do the R2-S65C woofers need?

A: The woofers need a mounting depth of 6.3cm and a cut-out diameter of 13.5cm.

Q: Can I adjust the tweeter level on the R2-S65C?

A: Yes. The high-pass crossover networks let you set the tweeter level to -3dB, 0dB or +3dB, and in many cars they can be fitted using the original door wiring.
