The Era of High-Resolution Audio
We are enthusiastic supporters of Alpine's commitment to bringing high-resolution audio to a wider audience, particularly within the automotive realm. Leveraging the cutting-edge technology developed for their esteemed F#1 Status Series, Alpine presents the Next Generation S-Series car speakers, allowing every driver to experience the captivating intricacies of their favorite high-resolution audio files at an irresistible price point. While we recommend utilizing aftermarket power to fully unleash the potential of these speakers, their remarkable performance is evident even when powered by factory systems, thanks to their exceptional frequency response that ensures a meticulous and authentic sound reproduction.
Revolutionary Design Elements
Alpine has ingeniously incorporated highly effective materials and exclusive design components to optimize the capabilities of these speakers. The woofer cone, expertly engineered using a blend of polypropylene, glass fiber, and mica materials, delivers the essential balance of high output and low distortion required for impeccable high-resolution performance. Additionally, the woofer features the High Amplitude Multi-Roll (HAMR) surround, allowing for maximum cone excursion and elevating the bass reproduction to its finest. Complementing the woofer, a 3/4" silk dome tweeter unveils the intricate nuances of high-frequency sounds that were previously absent with factory-installed speakers.

NVX SDBSK2 Premium Stealth Black
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.
