A bit of a collector’s piece, and A$895 is on the high side for a single 2405H unless it’s exceptionally clean, fully tested, and ideally comes with the original bracket or other useful extras. Typical used pricing in the results clusters around roughly A$700–A$1,000 for a pair, which puts a lone unit like this closer to the upper end of the market than a bargain.
What keeps it interesting is the 2405H’s reputation for that classic JBL top-end: open, lively, and very usable in vintage horn or studio-style systems. If the diaphragm is healthy, the level matched, and the cosmetics are genuinely nice, it can still be a worthwhile buy for someone restoring a JBL setup. At this price, though, I’d want clear proof of performance and no hidden issues before jumping in.

JBL traces its roots to 1946, when pioneering audio engineer James Bullough Lansing founded the company in Los Angeles, California, initially as James B. Lansing Sound, Incorporated. A veteran of loudspeaker design from earlier ventures like the Lansing Manufacturing Company and collaborations on Hollywood's first practical cinema systems, Lansing infused JBL with his relentless pursuit of acoustic clarity and fidelity. Though he passed away in 1949 amid financial strains, the brand endured under new leadership, accelerating in 1969 with acquisition by Harman International—now under Samsung—fueling global expansion and innovation.
JBL excels across professional and consumer audio realms, renowned for its loudspeakers that dominate studios, touring rigs, cinemas, and home setups. Iconic models like the D-130 woofer, Paragon stereophonic system, and L-100 Century defined eras of high-output sound, while modern lines span portable Bluetooth speakers, wireless headphones, soundbars, and pro monitors. The brand prioritizes robust transducers, advanced horns, and diamond-surround tech over niche components like turntables, DACs, or cables.
Positioned as a mid-tier powerhouse with pro-grade heritage, JBL commands respect among discerning buyers for delivering punchy, reliable performance at accessible prices, bridging live-event energy and home listening without high-end esoterica. Its vintage icons draw collectors, yet contemporary ubiquity in arenas and everyday gear cements market dominance for those valuing scale and excitement over boutique refinement.
