About the Alpine R2-S652

Your entry to high-res audio

Your entry to high-res audio
Enjoy the details in your favourite high-resolution audio files with this set of Next-Generation R-Series component woofers, tweeters, and external 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. Their ultra-wide frequency response ensures a detailed, authentic sound, and thanks to power-handling up to 100 watts RMS, you can play 'em loud!
Minimal distortion
Alpine optimizes their R2-S652 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-fibre 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.
Equipped for pros
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, so you'll have helpful options. Plus, you'll get robust external crossovers to ensure your speakers receive the right frequencies to perform at their very 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. 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:

I've owed about 8 pairs of the previous version of the alpine r2. The sound quality is magnificent. I've ordered 4 pairs of these new pro models. Will install in my wife's car this weekend and when my back order of the other two sets comes in they will go in my new truck.
