Alpine S-S57 5×7″ 2-Way Coaxial S-Series Car Speakers
The Alpine S-S57 5″x7″ 2-way speakers are no exception, considering the Alpine has been building quality car speakers for decades. If you’ve been living with anemic factory sound, this step up in range, tone definition, and power handling will make you giddy just about every time you hop behind the wheel. And if you’re really jonesing for a boost in sound quality, hook them up to a powerful aftermarket stereo or amp for increased performance. The new cosmetics of the S-Series looks good in nearly any car and their shallow mounting design allows for easy installation in a wide range of door panels. As well, their high-efficiency design can run off of the power from the factory or Alpine head unit, resulting in an easy system improvement for any vehicle.
Ballistic sound dampening material is an elastomeric butyl and aluminum layered vibration dampener that conforms and fuses easily to sheet metal and other hard surfaces. The Alpine S-S57 5″x7″ 2-way speakers greatly reinforces the interior of the Door, Floor, or Trunk and reduces vibrations and road noise. Properly applied Ballistic will even help prolong your speakers life by diminishing exposure to moisture and helping to stabilize tempters. The Alpine S-S57 5″x7″ 2-way speakers are relatively odor free, designed to eliminate the smell issue without sacrificing effectiveness. Perma Stick allows Ballistic to adhere to almost any surface. The better your sound dampening material adheres the more effective it will be.
INCREASED DRIVING POWER AND CONTROL
The S-Series speakers have a large voice coil. The 6.5-inch and 6×9-inch models have a 35-mm voice coil, and this large voice coil size increases their driving power and control of the motor. 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.
INCREDIBLE LINERITY AND ACCURACY
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.
SMOOTH, WIDE FREQUENCY RESPONSE
The 1-inch silk dome is perfect for recreating pleasant upper range response without creating listening fatigue in the vehicle. The soft silk material ensures wide frequency response and durability for long term playback.
