Sky High Car Audio FXB Series 12" Subwoofer – 1500W RMS Dual 2 Ohm / Dual 4 Ohm
Sold by AudioSellerz.com
The Sky High Car Audio FXB Series 12" Subwoofer is a serious 1500W RMS 12 inch car audio subwoofer built for real-world abuse, big output, and strong motor control—without jumping into crazy flagship pricing. Part of the FXB: “Sky High Performance. Everyday Price.” line, this 12" driver takes the same engineering mindset as Sky High’s top subwoofers and packs it into a budget-conscious, heavy-hitting platform.
At the core of the FXB 12 is a 3" 4-layer high-temp voice coil paired with a rugged double-stacked ferrite motor. This combo is rated to handle 1500W RMS and is designed to be pushed hard daily without giving up. The larger FXB sizes (10", 12", 15", 18") all share this big-coil, big-motor architecture, giving them way more thermal capacity and control than typical “budget” subs.
The suspension uses a large, progressive spider and high-roll surround to support serious excursion, while the frame and motor structure are tuned for strong mechanical control and air movement. Available in dual 2 ohm (D2) and dual 4 ohm (D4), the FXB 12 is easy to match with stout monoblock amplifiers for single-sub builds, pair setups, or multi-woofer systems.
In the right ported or sealed enclosure, the FXB Series 12" delivers deep, hard-hitting bass with enough cone area and Xmax to move real air—perfect for street demos, loud dailies, or budget SPL-style builds.
