About the Alpine R2-S653

Your entry to high-res audio

Alpine's Next-Generation R-Series Pro 3-way component speaker system harnesses trickledown technology from their famed F#1 Status line to deliver a full-bodied, six-speaker experience that's high-res capable. Play your high-resolution music files with confidence, knowing that the ultra-wide frequency response of the included woofers, midrange drivers, and tweeters will provide the detailed, authentic sound you're looking for. 

Minimal distortion

Alpine optimizes their R2-S653 6-1/2" 3-way component speaker system for near-perfect sound from premium sources. Both the woofer and midrange combine a highly rigid aluminum frame and a lightweight glass-fiber reinforced cone to keep the sound clean. The high-amplitude multi-roll surrounds of these drivers maximize 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 a threaded removable housing and a swivel-mount design to make sure you have what you need to make them sound their best.

These speakers make a great addition to any high-powered system, thanks to power-handling up to 100 watts RMS. Hook ‘em up and play ‘em loud!

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. 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. The installed tweeter dimensions are:

  Flush Mount (swivel) Angled Surface Mount
Mounting Depth 0.65" N/A
Mounting Height 0.378" 1.325"
Cutout Diameter 2.0" N/A
Frame Diameter 2.285" 1.82" x 1.71"

Midrange: The midrange drivers are not a standard size; they are similar to a 3½, but have a different screw hole pattern. They are top mounted and have these dimensions:
