Sky High Car Audio FXB Series 15" Subwoofer – 1500W RMS Dual 2 Ohm / Dual 4 Ohm
Sold by AudioSellerz.com
The Sky High Car Audio FXB Series 15" Subwoofer is a heavy-hitting 1500W RMS 15 inch car audio subwoofer built for real daily abuse, street demos, and budget SPL-style systems. Part of the FXB – “Sky High Performance. Everyday Price.” line, this 15 takes the same engineering mindset as Sky High’s higher-tier subs and packs it into a more accessible package.
FXB 12–18" models are built around a rugged double-stacked ferrite motor and a 3" 4-layer high-temp voice coil, giving them strong motor force, excellent thermal capacity, and the ability to be pushed hard day after day. A full-size 10" progressive spider pack and high-excursion suspension provide about 30mm of one-way Xmax, keeping the cone controlled even at high output while still delivering deep, loud bass.
A hardened paper cone and foam surround maintain accuracy and output at high excursion, while the cast aluminum basket keeps the structure rigid without unnecessary weight. Push terminals make it easy to run heavy-gauge speaker wire cleanly in real-world installs.
Available in dual 2 ohm (D2) and dual 4 ohm (D4), the FXB 15 is easy to pair with serious monoblock amplifiers—whether you’re running a single 15 in a strong daily box or multiple 15s in a wall or big SUV build.
