Sold by AudioSellerz.com

The Sky High Car Audio FXB Series 18" Subwoofer is built for people who want real 18 inch bass without jumping into four-figure woofer territory. Part of the FXB – “Sky High Performance. Everyday Price.” line, this 18" sub is designed to bring serious low-end output, strong motor control, and real-world reliability to street demos, loud dailies, and budget SPL-style builds.

Engineered with the same design mindset as Sky High’s higher-tier series, the FXB line focuses on motor strength, coil durability, and suspension control—not just flashy spec-sheet numbers. The FXB 18 sits in the 1500W RMS class, using a heavy-duty motor, big coil, and robust suspension to handle real power in real enclosures.

With its huge cone area and long throw design, the FXB 18 can move a serious amount of air when paired with the right amp and box, giving you deep, room-filling bass in SUVs, vans, and wall builds.
