The Sky High Car Audio FXXL Series 12" Subwoofer is the flagship ferrite woofer from Sky High – built for hardcore demo builds, competition lanes, and ultra-violent daily systems that actually see real use, not just pretty numbers on paper. Rated at 5000 watts RMS, this 12 inch subwoofer uses a huge 4 inch 8-layer high-temperature voice coil and a quad-stack ferrite motor to deliver massive output, serious control, and the thermal headroom you need when you lean on big power for long stretches.

At the heart of the FXXL 12 is that 4" high-temp coil and a quad-stacked 9.96" Y35 ferrite motor, designed to move a lot of air, stay cool, and stay linear at high excursion. Aluminum shorting rings, pole venting, and drilled/tapped backplate holes are built in to improve cooling and give enclosure builders more options for reinforcement or additional airflow tricks. This motor package is aimed at the sweet spot between SPL monster and brutal daily driver – big motor strength with real musical control.

Mechanically, the FXXL 12 uses a 10" progressive spider pack, fiberglass cone support, and a hardened paper cone with a recessed seat for the forged carbon-style dust cap, giving the moving assembly serious rigidity at full stroke. A precision-molded foam surround is tuned for control, compliance, and long life at extreme excursion, while a secondary internal pressure cap adds more strength to the main cap and helps balance pressure under heavy use.

On the outside, the FXXL carries Sky High’s stealth all-black look – carbon dust cap, tooled SHCA magnet boot, and oversized push terminals for secure, high-current connections. The motor and basket are designed with airflow in mind from every angle, so when you pair this 12" FXXL with the right box and real electrical, it’s built to survive serious clamp numbers and long demos. Engineered with low Fs and high BL, it plays low, hits hard, and stays precise across the bass band.

Available in dual 1 ohm (D1) and dual 2 ohm (D2) configurations, the FXXL Series 12" makes wiring simple whether you’re running a single powerhouse woofer or stacking multiples in a wall, blow-through, or big SUV build. It’s a perfect match for high-power Korean or Brazilian monoblocks in the 5k+ RMS range when paired with proper electrical and a correctly designed enclosure.

Sky High also supports the FXXL line with box design resources so you can get the most out of the sub in ported, 4th order, or 6th order enclosures—ideal if you’re trying to squeeze every last dB and still keep the woofer alive.

If you’re ready to move into a true flagship-level 12 inch subwoofer that can take real power, the Sky High Car Audio FXXL Series 12" 5000W RMS subwoofer is the one to build a serious system around—competition grade, demo ready, and daily drivable when it’s set up right, backed by the crew at AudioSellerz.com
