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:
