About: Skar Audio SDR-18 18" 600W RMS Car Subwoofer

The Skar Audio SDR-18 subwoofer was designed to redefine the term "daily" subwoofer, both in terms of power output and acoustic responsiveness across the entire low end frequency range. The engineering considerations that went into developing this 18-inch subwoofer are extensive, and contribute to why the SDR series has continued to be one of the most popular subwoofer lines we have ever released.

Featuring a 2.5" 4-layer high temperature copper voice coil, the SDR-18 can operate at peak performance for hours on end with the peace of mind knowing that it can handle the brutality. Combine that with the top-tier, high flux ferrite motor of this driver, and it is by no surprise that this subwoofer can reproduce low end bass frequencies with authority. Furthermore, we integrated a unique red nomex spider suspension system into the design that utilizes the perfect blend of stiffness and flexibility. The aforementioned components of the SDR-18 as well as its advanced air flow cooling design, are what ultimately allow for the incredible responsiveness & power handling of this subwoofer.
