Alpine R2-S69 6x9 Coaxial Speakers with Foam Rings

This bundle pairs Alpine R-Series 6x9 coaxial speakers with RKFR6 foam rings, a pry kit and a coozy. The speakers use 16 x 24 cm composite-basket woofers and 4,3 cm magnesium hard-dome tweeters with flush or on-dash mounting. Peak power is 300 Watts and RMS power is 100 Watts at 4 Ohm nominal impedance.

Who these suit and who should look elsewhere

Buyers upgrading factory 6x9 locations who want reduced panel vibration and improved mid-bass response will benefit from the included foam rings. Installers needing shallower mounting depth than 7,6 cm or a cutout smaller than 14,9 x 22 cm cannot use these woofers. Systems requiring higher sensitivity than 88 dB SPL or lower frequency extension below 65 Hz should consider other options.

Deciding specification: 65 Hz to 40 kHz frequency

The 65 Hz to 40 kHz range sets the usable bandwidth for music reproduction. If your install needs deeper bass output below 65 Hz, these speakers will not meet that requirement without a subwoofer. The range also determines how much high-frequency detail the magnesium tweeters can deliver in a High-Resolution audio system.

Questions about this item

Will these 6x9" coaxial speakers fit the same cutout as my old 6x9" units?

The woofer cutout measures 14,9 x 22 cm, matching the standard 6x9" opening, so they drop into the existing holes without new drilling.

How can I confirm the tweeters are delivering the 40 kHz high-frequency detail after install?

Play a 1 kHz tone at 1 W and verify 88 dB SPL at 1 m with an SPL meter, then sweep to 40 kHz — smooth output indicates the 4,3 cm magnesium hard-dome tweeters are functioning.

Does the bundle include mounting hardware, or do I need separate screws and rings?

The box contains a pair of R2-S69 speakers, two RKFR69 foam rings, a pry kit, speaker grilles and an Alpine coozy; no extra fasteners are required for standard door installation.
