Alpine 2 Pack S-S57 S Series 5X7 Inch Coaxial 2 Way 230 Watts Car Speakers

Alpine 2 Pack S-S57 S Series 5X7 Inch Coaxial 2 Way 230 Watts Car Speakers

Alpine S-Series speakers have a large voice coil. The S-Series speakers are the first in the industry to use a material called CFRP (Carbon Fiber Reinforced Plastic), a very lightweight yet rigid material. On a standard, off-the-shelf oval cone, the edges are naturally weaker than the center due to the elongated shape. Alpine’s patented H.A.M.R. (High Amplitude Multi-Roll) surround is now found on the S-Series speakers.

Alpine's S-Series

Looking to upgrade your OEM sound system? Alpine's S-Series Speakers have been redesigned with upgrades to voice coil size and cone material to provide premium sound quality, making them the new benchmark for entry OEM upgrades! With both coaxial and component style speakers, the S-Series is certain to have the size and configuration you need to upgrade your vehicle’s sound system.

Superior Sound: HAMR Surround

Alpine’s patented H.A.M.R. (High Amplitude Multi-Roll) surround is now found on the S-Series speakers. This proven technology increases excursion while maintaining accuracy and linearity. The multi-roll design allows for an even unfolding of the surround which creates incredible linearity and colorization rejection.

Superior Performance: Carbon Fiber Reinforced Plastic

The S-Series speakers are the first in the industry to use a material called CFRP (Carbon Fiber Reinforced Plastic), a very lightweight yet rigid material. On a standard, off-the-shelf oval cone, the edges are naturally weaker than the center due to the elongated shape. Since the CFRP material is directional, it can be manipulated during the molding process to strengthen the areas of the cone that are normally weak. The result is rigidity throughout the cone that delivers accurate and efficient performance. The ability to manipulate the CFRP material during the molding process is currently exclusive to Alpine and the S-Series speakers. Alpine has three patent-pending procedures in support of this innovative manufacturing process. With special consideration given to oval shaped speakers that are commonly found inside the doors of most vehicles now, this process helps to ensure that distortion or warp are a thing of the past with your listening experience regarding oval shaped speakers. .

Wide Frequency Response

The 1-inch silk dome on the tweeters is perfect for recreating pleasant upper range response without creating listening fatigue. The soft silk material ensures wide frequency response and durability for long term playback. Not sure what a tweeter exactly is? A tweeter is a small speaker that produces the upper range of sound, or treble. They provide a crisp, well-detailed sound that enhances the listening experience in conjunction with the woofers, which enhance the lower range of sound, or bass. Together, this provides a full range of sound that most factory speakers are unable achieve.

Keep in mind, there is more to the S-series than just speakers. Pair your speakers with other S-series products like the S-A60 M S-Series Class D Mono Amplifier, subs, and even an Alpine Receiver to complete your system to experience superior sound quality that doesn’t break the bank.
