Woofer Mounting: Although Alpine describes the woofers' size
as 6-1/2, without adapter brackets the woofers fit many standard 6-3/4 applications.
Using the two types of adapter brackets included, they can be mounted in a wide
variety of 6-1/2, 6-3/4, 5x7, and 6x8 applications. Please enter you vehicle
information to confirm fit.
HAMR Surround: Type-R speakers use Alpine's multi roll HAMR
surround (patent pending), a technology developed for Alpine subwoofers that
maintains control and stability at higher volume levels. HAMR surround combines
increased cone area and long linear cone excursion for deep, powerful bass
Tweeter Mounting Options: The tweeters come installed in a
swiveling flush-mount housing. You can also install the tweeters behind factory
grilles using the included stealth mount brackets. The stealth mount brackets
can be top or bottom mounted. The installed tweeter dimensions are:
| ||Flush Mount (swivel) ||Factory Location (bottom
mount) ||Factory Location (top mount) |
|Mounting Depth ||0.657" ||0.756" ||0" |
|Mounting Height ||0.436" ||0" ||0.756" |
|Cutout Diameter ||2.005" ||N/A ||N/A |
|Frame Diameter ||2.277" ||1.723" x 2.5" ||1.723" x 2.5" |
Crossovers: The R-S65C features low-pass crossovers attached
to each woofer's input terminal and separate high-pass crossovers in-line between
the woofers and tweeters. Because the crossovers are separate, the system can be
bi-amped. Two-sided tape is included to mount the high-pass crossovers and their
- Width: 2.475" (2.686"
- Height: 0.96"
- Depth: 1.27"
Tweeter Attenuation: Each crossover has four tweeter level
options, allowing you to precisely tune the high frequencies to the car interior
and tweeter placement. Using the supplied jumpers select 0dB (no attenuation),
-2dB, -4dB, or -6dB.
