ALPINE R-S652 : HANDLES UP TO 100 WATTS
Alpine has designed these speakers to work perfectly with your car stereo, but they’ll really come into their own when you power them with an outboard amp. Power handling up to 100 watts RMS ensures you can get big, dynamic sound and plenty of volume out of these sturdy speakers. If you like to turn it up loud, Alpine R-Series speakers will give you a no-regrets sound upgrade.
MOUNTING
Although Alpine describes this speaker size as 6½, the required cutout is larger than a typical 6½, and without adapter brackets the woofers fit many standard 6¾ applications. Using the included adapter brackets, they can be mounted in a variety of 6½ and 6¾ applications. Please enter you vehicle information to confirm fit.
DRIVER MATERIALS
The R-Series speakers use Carbon Fiber Reinforced Polymer (CFRP) woofer cones. This high-strength, lightweight material is formed with its fibers aligned in the same direction as the curve and shape of the cone, thereby reducing resonant peaks. This balance of light weight and rigidity improves the speakers’ mid-bass performance and dynamic range. CFRP is also used for the tweeter diaphragm, enabling the system to perform into the 40 kHz range.
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.
PIVOTING TWEETER
The tweeter pivots approximately 15° in any direction in its housing, so it can be angled to optimize imaging.
