About the Alpine Type-S SPS171A
You'll be dazzled by the vibrant imaging of Type-S component systems. Expect shining clear sound, thanks to Alpine's combination of innovative materials and design.
Install the SPS-171A 6-3/4" component system's 1" textile dome tweeters in either flush or surface mounts, then pivot them up to 15° to fine tune your stereo image and soundstage. The Layered Hybrid Fiber woofer cones produce deep, natural-sounding bass, thanks to a linear drive magnet design and the excellent sound-propagating qualities of the woofers' built-in wave guides. Handy adapter rings are included so you can mount the woofers in either 6-1/2" or 6-3/4" openings.
External 2-way crossovers channel frequencies to the proper drivers for seamless and efficient sound reproduction.

Product Research
Layered Hybrid Fiber Cones: Each Layered Hybrid Fiber cone consists of three different layers. The middle layer is constructed of paper. A natural mica compound is layered on the front of the paper diaphragm for good sound separation and clear music reproduction. The use of a highly rigid material on the back of the paper diaphragm minimizes noise, resulting in powerful bass and natural midrange.
Air-injected Rubber Surrounds: For a smoother response and improved durability, the woofers use air-injected rubber surrounds.
Linear Drive Magnet Design: The new magnetic circuit provides linear cone motion and a wide dynamic range.
Wave Guides: The wave guides align the sound waves coming from each cone for excellent music reproduction.
Adapter Rings: The supplied adapter rings allow the speakers to be installed in a standard 6-1/2" opening or an oversized GM/Chrysler 6-1/2" opening. The adapter rings have tabs that must be broken off when the speakers are mounted in a standard 6-1/2" opening.
OEM Spacer Rings: In select Honda vehicles, the supplied OEM spacer rings can be used to replace the factory mounting cups.
Soft Dome Tweeters: Each tweeter uses a 1" textile dome tweeter for smooth, clear highs.
Tweeter Mounting Options: The tweeters may be flush, swivel angle, or fixed angle mounted. The tweeters swivel in the flush and swivel angle housings, so you can control the direction of your high frequencies.
Tweeter Mounting Dimensions:
| Flush Mount (swivel) | Swivel Angle Mount | Fixed Angle Mount | |
|---|---|---|---|
| Mounting Depth | 1.809" | 0.672" (screw depth) | 0.668" (screw depth) |
| Mounting Height | 0.793" | 1.891" | 1.358" |
| Cutout Diameter | 1.939" | N/A | N/A |
| Frame Diameter | 2.237" | 1.896" | 1.862" |
Selectable Tweeter Output Level: Each crossover allows you to select the tweeter output level according to system requirements and personal preference. The tweeter level may be set to "-6 dB", "-3 dB" or "0 dB".
Tweeter Protection: A tweeter protection circuit diverts excessive power away from the tweeters.
2-Way Crossovers: The crossovers feature a 12 dB/octave high-pass network for the tweeters and a 6 dB/octave low-pass network for the woofers.
Input/Output Connections: The crossover inputs and outputs are gold-plated screw terminals.
Mounting: There are two mounting holes in the base of each crossover.
Crossover Dimensions: L=4.673", W=2.563", H=1.324"

They sound awesome and play the the highs good enough to overcome my two JL AUDIO 12's... The speaker is really deep so make sure it fits i had to do some MAJOR modifications to get it to fit but when i did they slammed. I love them. BenzMan
