Sold by AudioSellerz.com

The Sky High Car Audio FE Slim Series 10" Subwoofer (FE-10SL) is a shallow-mount 10 inch sub built for tight spaces, stealth installs, and clean daily bass without needing a huge enclosure. With only 3.62" (91.95mm) mounting depth and a 2" dual voice coil rated at 250 watts RMS, this FE-SL 10 is perfect for trucks, standard cab pickups, behind-seat boxes, under-seat enclosures, and small trunk builds where traditional subs won’t fit.

Powered by a 61oz underhung ferrite motor, the FE-10SL is engineered for tight, controlled low end and efficient output on modest power. A 7.1" (180mm) spider and 11mm Xmax (one-way) give this shallow 10" real stroke capability, so it doesn’t feel “weak” or thin like typical budget shallows. It’s tuned for musical daily use—great on hip-hop, rock, and bass-heavy playlists in compact systems.

Like the rest of the FE-SL (Slim Line) family, the FE-10SL uses an all-new tooled SHCA shallow basket designed specifically to reduce depth while keeping motor strength and mechanical control. This is not a generic off-the-shelf shallow woofer—Sky High built the line from the ground up to fix the usual shallow-mount problems: limited excursion, weak spiders, and rubbing surrounds in tight boxes.

All FE-SL subs share a uniform basket and dustcap design, giving your system a clean, consistent look whether you’re running a single FE-10SL or mixing 8", 10", and 12" models in a multi-sub layout. Available in dual 2 ohm (D2) and dual 4 ohm (D4) options, wiring is simple for single-sub and multi-sub setups on small to mid-size monoblocks.
