Small Size. Big Conversation. Endless Possibilities.
The Sky High Car Audio FXXL 3.5” Mini Subwoofer takes everything that defines our flagship lineup and compresses it into a palm-sized powerhouse. Built with the same aggressive styling and attention to detail as its larger FXXL brothers, this miniature woofer features a forged carbon fiber dust cap, an all-black stealth aesthetic, and your choice of ferrite or neo motor structures—delivering both visual impact and real functionality in an ultra-compact form.
The FXXL 3.5” Mini Sub opens the door to a wide range of creative uses:
Retail Display Piece – Every dealer needs one. Put it on the counter and watch customers pick it up. It naturally starts conversations about your full subwoofer lineup.
RC & Mini Builds – Perfect for RC cars, custom scale builds, or compact demo setups where space is limited but impact still matters.
Desktop Audio Projects – Build a small enclosure and pair it with a micro amp for a unique desk setup with real sub-bass presence.
Show & Demo Props – Great for trade shows, events, and social media content—small enough to grab attention instantly.
Collector / Novelty Item – A must-have for audio enthusiasts who appreciate engineering scaled down to the extreme.
This isn’t just a gimmick—it’s a true, working subwoofer designed to move air, produce low-end response, and spark curiosity the second someone lays eyes on it. Whether sitting on a counter or wired into a small-scale build, the FXXL 3.5” is impossible to ignore.
