Experience the Era of High-Resolution Audio

We greatly admire Alpine's dedication to bringing high-resolution audio to more car enthusiasts. Drawing upon the technological advancements of their esteemed F#1 Status Series, Alpine's Next Generation S-Series car speakers offer an enticing opportunity to indulge in the exquisite intricacies of your beloved high-resolution audio files, all at an affordable price. While we recommend utilizing aftermarket power for optimal performance, these speakers deliver exceptional results even when powered by factory systems, thanks to their remarkably broad frequency response that guarantees a rich and authentic sound experience.

Unleashing Innovation through Materials

Alpine has infused these speakers with unmatched capabilities by incorporating highly efficient materials and exclusive design elements. The lightweight woofer cone, meticulously crafted from a blend of polypropylene, glass fiber, and mica materials, effortlessly produces the perfect balance between high output and low distortion, essential for outstanding high-resolution performance. Amplifying the bass to its finest, the woofer's High Amplitude Multi-Roll (HAMR) surround allows for maximum cone movement, bringing out the best in low-frequency reproduction. Moreover, the inclusion of a 3/4" silk dome tweeter ensures that you won't miss a single detail in the high-frequency range, enhancing your audio experience beyond what factory-installed speakers can offer.

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

NVX SDBSK2 Premium Stealth Black

The following review is for SDBSK2, which is a part of the bundle you are viewing.

For the price, I wish it came with a bit more of the material compared to other packages, but it definitely does what it's supposed to and will make a noticeable difference if you knock on the door/panel where it was placed vs where it wasn't.
