Features
Woofers: The Alpine Type-R
series component speakers feature woofer cones made of hybrid layered-pulp with
mica coating for great bass response. For durability and superior linearity, the
woofers have rubber surrounds.
Motor Structure: The
High-performance Linear Drive Motor structure features a large magnet that is
almost as big as the voice coil diameter. Its dual radial magnet and twin gap,
combined with a square, edge-wound voice coil, gives the diaphragm linear
movement over a much greater range. This design allows the speaker to be
faithful to the input signal even during high excursion, for accurate musical
reproduction and deep bass.
Adapter Rings: The SPR-13S
component speakers come with a pair of adapter rings. The rings allow
you to install the woofers in 6"x8" openings. The tweeter can be
mounted in the adapter ring, or mounted separately. The rings have a tweeter
plug that can be removed if you choose to mount the tweeter in the adapter ring.
Tweeters
Tweeters: The SPR-13S component speakers
are equipped with 1" (25mm) silk ring-dome tweeters for greater detail and
bright, crisp highs.
Tweeter Mounting Options: The
tweeters come installed in a swiveling flush-mount cup. You can also install the
tweeters in a stealth mount when it will be hidden behind a factory grille. The
stealth mount can be used as a top mount or a bottom mount.

Crossovers
Two-way
Crossovers: The SPR-13S component speakers come with 2-way external
crossover networks. The crossover features a 6dB/octave low pass filter for
the woofers, and a 12dB/per octave high pass filter for the tweeters.

Attenuation: The crossover has a 7-level tweeter adjustment to allow you
to precisely tune your high frequencies. Using the supplied jumpers, you can
select 0dB (no attenuation), or 6 levels of attenuation: -3dB, -4dB, -5dB,
-6dB, -7dB and -8dB.
Input/Output
Connections: The crossover features
gold-plated screw terminals for the amplifier inputs and the woofer and
tweeter outputs. The screw terminals are hidden by the crossover cover.

mounting screws. Each crossover comes with flat speed clips.
