Why Choose Alpine S2-S40C Component System?
Give More Drivers Access to High-res Audio
The Alpine S2-S40C is a compact and high-performance 4-inch component speaker system designed to deliver exceptional audio quality in your car. This speaker system includes two 4-inch mid-bass woofers and two 1-inch silk dome tweeters.
Ultra-wide Frequency Response
Despite its small size, the S2-S40C packs a punch with a peak power handling of 140 watts and an RMS power rating of 45 watts. The 4-inch woofers feature a specialized hybrid cone, which ensures rigidity and precise control over bass frequencies, resulting in clear and impactful sound reproduction.
Crafted From Polypropylene
Alpine's patented High Amplitude Multi-Roll (HAMR) surround technology enhances the woofers' excursion capability while minimizing distortion, improving mid-range performance. The 1-inch silk dome tweeters are adept at reproducing detailed and smooth high frequencies, enriching your music with clarity and finesse. The tweeters can be swiveled, allowing you to direct the sound towards your listening position, optimizing the soundstage and imaging.
High-frequency Detail You've Been Missing
With their low-profile grilles, the Alpine S2-S40C speakers blend seamlessly with your car's interior while protecting the drivers from potential damage. The Alpine S2-S40C component speaker system offers an impressive audio upgrade for car audio enthusiasts seeking a space-saving solution without compromising sound quality.
Frequently Asked Questions (FAQ)
- • Why do the tweeters sound too bright after installation?
This is often caused by their mounting position, equalizer settings, or crossover placement within the system. Adjusting the tweeter angle and fine-tuning your audio settings usually creates a smoother listening experience.
- • What kind of dome material do the tweeters use to produce their high frequencies?
The tweeters are built with a premium cloth silk dome design that delivers smooth, articulate, and non-fatiguing high-frequency playback. This material allows the system to easily reproduce subtle vocal details up to 40,000 Hz for high-resolution audio performance.
- • Why is one tweeter or woofer not producing any sound?
This is commonly caused by loose wiring, incorrect crossover connections, or reversed speaker polarity during installation. Inspecting every connection and confirming the crossover wiring usually resolves the issue.
- • Can I install the tweeters in my factory dash or door locations?
Yes, the included flush-mount hardware and additional mounting accessories support several installation methods depending on your vehicle. Choosing the proper mounting location helps improve stereo imaging and vocal clarity.
- • Why do the speakers distort when I turn the volume up?
Distortion usually occurs because of amplifier clipping, excessive bass boost, or incorrect crossover settings. Proper amplifier gain adjustment and balanced equalizer settings typically eliminate the problem.
- • Can I detach the fixed grilles from the flush mount tweeter housings to customize the look?
No, the grilles on the flush mount pods are permanently attached to protect the delicate silk domes from physical contact.
- • Why do the door panels vibrate more after installing these speakers?
The improved output can cause loose interior panels and factory mounting surfaces to resonate. Applying sound-deadening material and securely mounting the speakers usually reduces unwanted vibrations.
- • What is the peak power rating of this component bundle compared to its continuous capability?
The component system is rated to handle a maximum peak power burst of up to 140 watts for handling rapid musical spikes. However, for continuous daily operation, you should adjust your amplifier setup to match its clean 45-watt RMS rating.
- • How do the included flat mounting flanges help during a factory replacement?
The flat mounting flanges are engineered to replicate the standard bolt patterns used by several major vehicle manufacturers. They screw directly onto the woofer basket so you can drop the new drivers into OEM mounting locations without drilling fresh holes.
