Your entry to high-res audio

Enjoy all the details in your favorite high-resolution audio files with this set of Next-Generation R-Series component woofers, tweeters, and convenient in-line crossover systems. Using technology developed for their flagship F#1 Status Series, Alpine built these speakers to be fun for enthusiasts interested in high-resolution audio playback.

Minimal distortion

Alpine optimizes their R2-S65C 6-1/2" 2-way component speaker system for near-perfect sound from premium sources. The woofer's combination of a highly rigid aluminum frame and a lightweight glass-fiber reinforced woofer cone helps minimize distortion. The high-amplitude multi-roll surround maximizes impact while maintaining linearity, so you'll get punch with minimal distortion. And speaking of a little more punch, the woofer's ferrite magnet and large motor structure will pump up the mid-bass in your music.

Loud and fun

All the exquisite detail you need is handled by the 1" magnesium hard dome tweeters, which contribute to the "loud and fun" sound associated with Alpine's R-Series. Because tweeters can be challenging to install, Alpine provides in-line crossover systems, a threaded removable housing, and a swivel-mount design to make sure you have what you need to make them sound their best.

Features

Size Note: Alpine describes this woofer size as 6½, but because it requires a larger cutout than a standard 6½, Crutchfield has traditionally referred to this size as 6¾. Without adapter brackets the speakers fit many standard 6¾ applications. Using the included adapter brackets they can also be mounted in a variety of 6½, 6¾, 5x7, and 6x8 applications. Please enter your vehicle information to confirm fit.

HAMR Surround: The R-Series speakers incorporate Alpine's patented High-Amplitude Multi-Roll (HAMR) surround, a technology developed for Alpine subwoofers that maintains control and stability at higher volume levels. HAMR surrounds combine increased cone area and long linear cone excursion for deep, powerful bass response.

Tweeter Mounting Options: The tweeters come installed in a flush-mount housing. Once mounted, the tweeters pivot approximately 15° in any direction, to improve the stereo image. Angled surface-mount housings are also included, or you can install the tweeters behind factory grilles using the included stealth mount brackets. The stealth mount brackets can be top or bottom mounted; they have multiple tabs that can be removed when not needed. The installed tweeter dimensions are:

  Flush Mount (swivel) Angled Surface Mount Factory Location (bottom mount) Factory Location (top mount)
Mounting Depth 0.65" N/A 0.653" 0.6"
Mounting Height 0.378" 1.325" 0" 0.075"
Cutout Diameter 2.0" N/A N/A N/A
Frame Diameter 2.285" 1.82" x 1.71" 1.726" 1.726"

Crossovers: A low-pass crossover with a 6 dB/octave slope is attached to each woofer's input terminal. The included 12 dB/octave in-line high-pass crossovers are wired between the woofers and tweeters. Each woofer has two positive and two negative terminals, one for input from the amplifier, and one for output to the tweeter (via the in-line high-pass crossover). The 12" output wires attached to the crossovers are terminated with quick slides that connect to the terminals on the 30" wires attached to the tweeters. The quick slides on the attached 31" input wires connect to the extra terminals on the woofers. Because the crossovers are separate, the system can be bi-amped. Two-sided tape is included to mount the high-pass crossovers; their dimensions are:

  • Width: 1½"
  • Height: 1¼"
  • Length: 2⅞" (3" including wire)

Tweeter Output Level: Each crossover has three tweeter output level options, allowing you to precisely tune the high frequencies to the car interior and tweeter placement. Using the supplied jumpers select -3 dB, 0 dB (flat), or +3 dB.

Q
Being glass fiber, are these capable of being marine grade?
kory  Apr 01, 2024
1 answer
A
Hey Kory, thanks for the question. While the Alpines do have a glass and fiber blend, the material while being a bit more resistant to getting wet compared to other speakers out there, Alpine has not designed their pieces to be used in a full marine setting as they would need to also design their magnets to be able to stand up to the elements, and these are just not up to that task.

Q
Where could I get one replacement tweeter and the crossover?
bryan  Jul 08, 2023
1 answer
A
We do not sell them as replacement parts and recommend contacting Alpine's customer support using 800-257-4631 to find a parts supplier.

Q
Would these speakers work in front knee panel and dash for 2014 jeep wrangler with the small tweeters on the dash?
jason  Apr 02, 2023
1 answer
A
Unfortunately, the magnet of these speakers will be too large to fit in the knee panels.
