The Alpine R-S65C.2 is a 6.5-inch, 2-way, component car speaker system that includes two woofers, two tweeters, and two external crossovers. The woofers have a 35 millimeter voice coil for increased motor control over the bass output. The R-Series speakers are tuned with emphasis on the high- and low-end frequencies, so they deliver power while naturally producing bright, active sound. The R-S65C.2 also features high-resolution audio speakers with features such as HAMR Surround, carbon fiber reinforced polymer woofers, and tweeters.
