Alpine SPR Component Systems
If you appreciate good music, what better place to create an amazing audio system than in your car? Alpine's SPR Series component speakers offer you smooth, extremely accurate performance that'll set up a powerful soundstage.
High-tech woofers and tweeters
The SPR-17S component system utilizes 6-3/4" hybrid layered-pulp woofers that send out punchy midbass and vibrant midrange. Silk ring-dome tweeters highlight the vocals and instruments, delivering the subtle details that your old speakers could never reproduce. You can pivot the tweeters up to 15 degrees to optimize the stereo image in your car.
Crossovers direct the flow

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-17S component speakers come with two pairs of adapter rings. One set of rings allows you to install the woofers in 3-hole 6-3/4" GM/Chrysler installations or 3-hole 6-1/2" installations. The other set of rings will adapt the woofers for 6"x8" openings.
Tweeters: The SPR-17S 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.

Tweeter 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.
