US$650 is a fair asking price for the JBL MPX 600, sitting near the typical median for this unit in the used market. While a single unit recently sold for US$379.99, that was an outlier, and reliable listings often range between US$450 and US$700 depending on condition. At US$650, you are paying a standard price for a working amplifier, not a bargain, but certainly not an ambitious overcharge.
This amplifier is a worthwhile buy because it delivers robust power (600W/CH into 4Ω) and is built for professional durability, making it a trusted choice for touring and studio use. Its linear sound and reliable bridged-mono capability (1700W) offer significant upside for high-power applications. Since the price is fair and the model is well-regarded for its longevity, this listing represents a solid buying opportunity for an enthusiast seeking a proven, high-wattage stereo amp without the risk of questionable condition or missing accessories.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
