About the Alpine SPR-57C
You can't hear your favorite songs live in concert everyday, but Alpine's Type-R Series speakers can recreate the concert feel as they bring out your music's natural vibrance and detail.
The efficient SPR-57C 5"x7" speakers broadcast full low-frequency response with hybrid layered-pulp woofers, so you'll feel as if the bass guitarist is right beside you. Rubber surrounds resist deterioration and keep the woofers moving smoothly and consistently for accurate sound.
Premium silk ring-dome tweeters radiate bright vocals and sparkling instrumentals, without the annoying ear fatigue that inferior tweeters can cause. You can swivel the tweeters to provide the best stereo imaging for your car.

Woofers: The Alpine Type-R series coaxial 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.
Swivel Tweeters: The speakers are equipped with 1" (25mm) silk ring-dome tweeters for greater detail and bright, crisp highs. These tweeters can swivel to improve off-axis response in less-than-ideal installations. You can aim the tweeter by hand for best high frequency response at your listening position.
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.
