Alpine S2-S40 S Series 4" 同軸揚聲器

The Hi-Res certification is what sold me, and these little 4-inchers genuinely deliver crisp highs without harshness. Replaced my factory dash speakers and the clarity at low volume is immediately noticeable. They handle the midrange well for such a compact size, making podcasts and acoustic tracks

Installed these in my car’s dash last weekend and the clarity at higher volumes really surprised me for a 4-inch speaker. The tweeter’s crossover does a great job keeping vocals crisp without any harshness.

The Hi-Res certification actually makes a noticeable difference—streaming from Tidal sounds clearer and more detailed than my old setup ever did. Install was straightforward for a 4-inch coaxial, and the tweeter angle lets me aim the sound right at my ears.
