JL Audio Fathom F113 V1 Subwoofer (Active / Powered) JL Audio Fathom F113 V1 13" active sealed subwoofer. I am selling two of these units, this is number two. Am open to reasonable offers for both if someone wants dual subs. Very good condition, functions perfectly, some very slight blemishes to the paint. Comes with REQ mic & lead, power lead & manual. I no longer have the original carton. Pick up is preferred but I can drop to a pack and send at buyers expense if required. Plenty of reviews available online. Condition: Used Payment Method: EFT or Cash on Pick Up Region/State: (NSW) New South
This is the V1, so timing matters: it’s the earlier generation, but the Fathom F113 still has a strong reputation and the current replacement sits far higher in price. At A$3,000, this looks fair to slightly good rather than a steal, because used examples have shown up around A$2,700–A$4,200 while new/current retail for the line is much higher.
What you’re buying is a serious sealed sub with clean, fast, high-output bass and proper control — the kind of JL piece that still earns respect in 2-channel and home-theater systems. The upside is that a well-kept original-owner unit with the right accessories can be a long-term keeper; the main thing to verify is age, amp health, and that it’s complete, because parts and servicing matter more on an older heavyweight like this than on a newer mass-market sub.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 1975 in Miramar, Florida, by James Birch and Lucio Proni—whose initials inspired the JL name—the company began as a modest venture crafting high-fidelity home speaker systems and kits. Riding the car audio boom of the early 1980s, Birch and Proni pivoted to automotive applications, pioneering subwoofers like the W2, W5, and later the acclaimed W7 series, which featured patented technologies for superior bass performance. This heritage of engineering innovation, fueled by competition wins and relentless R&D, propelled JL Audio from a garage operation to industry trailblazer, expanding facilities in Florida and Arizona.
JL Audio excels in high-performance categories tailored to demanding environments, with a core focus on car audio amplifiers, subwoofers, and full-range speakers, alongside marine audio systems built for harsh saltwater conditions. Their lineup extends to home audio, including powered subwoofers and high-output enclosures like the Stealthbox, but eschews mainstream consumer fare such as turntables, DACs, headphones, or cables. Decades of acoustic expertise ensure products deliver precise, powerful sound reproduction across vehicles, boats, and living spaces.
Renowned as a high-end authority in mobile and marine audio, JL Audio commands premium positioning among discerning enthusiasts who prioritize uncompromised fidelity and durability over mass-market compromises. While mid-tier options exist, their reputation rests on boutique-level engineering—think W7 subwoofers that redefined bass standards—cementing a loyal following in competitive scenes and upscale installations. For the knowledgeable hi-fi buyer, JL Audio represents enduring excellence in specialized, physics-driven audio solutions.
