Alpine R2-S69C Component Set
The Alpine R2-S69C is a 6x9-inch high-resolution 2-way component speaker set built for car-audio enthusiasts who want detailed sound from a factory door location. It pairs a glass-fibre reinforced woofer cone with a 4,3 cm magnesium hard-dome tweeter for extended frequency response.
RKFR6 Fast Rings Upgrade
The bundle adds RKFR6 Roadkill Fast Rings that adhere directly to the metal door panel around each woofer. Their three-ring foam structure reduces panel vibration, minimises destructive wave interference and prevents front-to-rear wave cancellation for tighter mid-bass.
Straightforward Door Install
Both woofers and tweeters use standard 6x9 cutouts with a 7,6 cm mounting depth, while the tweeters offer flush or on-dash mounting flexibility. The peel-and-stick Fast Rings require a clean, flat surface; dust or curved panels can weaken adhesion and reduce their damping effect. Buyers needing shallower mounting depth or a coaxial design should look elsewhere.

Questions about this item
How often will the 100 Watt RMS crossovers or 4,3 cm hard-dome tweeters need replacement under normal use?
The 100 Watt RMS crossovers and 4,3 cm hard-dome tweeters are passive components with no scheduled replacement interval; they last the life of the speaker unless physically damaged.
What is the first limit reached when the 65 Hz to 40 kHz speakers run at high output for long periods?
Thermal compression in the 100 Watt RMS voice coils is the first limit, reducing output before the 300 Watt peak rating or mechanical excursion limits are reached.
How hot do the 4 ohm woofers and 88 dB sensitivity tweeters get during all-day playback?
The 4 ohm woofers and 88 dB sensitivity tweeters run warm but stay within safe thermal limits; the included RKFR6 foam rings also damp panel vibration that can add heat buildup.
