About the Alpine Type-R SPR-17LP
Alpine's audio engineers have used many of the high-end elements found in their acclaimed Type-R component systems to create the smooth-sounding, high-performance Type-R coaxial speakers.
The SPR-17LP 6-3/4" 2-way speakers feature multi-layered pulp cones with rubber surrounds that hang tough when you turn up the volume. Alpine builds the woofers with high-strength steel baskets and heavy-duty speaker motors for the steady support they need when the system is cranked. You'll enjoy full low-frequency response with low distortion.
Alpine's 1" silk dome Point Source tweeters radiate enveloping highs. A special tuned chamber behind each tweeter increases driver efficiency to ensure crisp, clear reproduction.

Features
Multi-layer Pulp Woofer Cones: Each speaker features a multi-layer pulp cone, for maximum strength, powerful bass and superior musical detail. For a smoother response and improved durability, the woofers use rubber surrounds.
1" Silk Dome Tweeters: Each speaker uses a 1" silk dome point source tweeter for better sound quality with less distortion. The unique design of the point source tweeter eliminates any cross cancellation between woofer and tweeter, and aligns the sound waves, for smooth sound performance.
GM/Chrysler Adapter Rings: The GM/Chrysler adapter rings allow the speakers to be installed in a standard 6-1/2" opening or an oversized 6-3/4" GM/Chrysler opening. The adapter rings have tabs that must be broken off when the speakers are mounted in a standard 6-1/2" opening.

Excellent choice as accent speakers. I have them in the rear doors of my '03 Trailblazer and they sound great. They are powered by an Alpine CDA-9851 HU, and sound great. For those who can afford one, I'm sure they would sound even better with an amp. But they perform great off head unit power.
