This £302 listing for a used pair of ADAM A3X monitors is a strong deal, sitting well below the typical used market range of roughly £350–£450 for a pair in good condition. The A3X is a discontinued generation now replaced by the T-series, but that age doesn’t diminish its value here—especially at this price, which is closer to the 25th percentile of used transactions.
The A3X remains well-regarded for its X-ART tweeter, delivering crisp, detailed highs and a frequency response up to 50 kHz that outperforms many budget rivals. Its 5-inch carbon-fiber woofers offer solid low-end for desktop or nearfield use. At this price, you’re getting pro-grade clarity without the premium cost of current models. If the pair is clean, with original cables and no cosmetic damage, this is a timely buying opportunity for enthusiasts seeking high fidelity on a budget.

ADAM Audio traces its origins to March 1999, when it was founded in Berlin, Germany, by Klaus Heinz amid the city's pulsating techno scene near Moritzplatz. Emerging as Advanced Dynamic Audio Monitors, the company quickly distinguished itself through innovative engineering, particularly the development of its signature Accelerated Ribbon Technology (ART) tweeter. Inspired by Oskar Heil's 1960s Air Motion Transformer, this handcrafted driver—still produced in Berlin—employs a pleated diaphragm to move air four times faster than traditional designs, delivering exceptional transparency and speed from the outset.
The brand focuses exclusively on professional studio monitors, eschewing amplifiers, turntables, DACs, headphones, or cables. Its active loudspeakers, from the iconic early-2000s S Series like the breakthrough S3A to modern lines featuring X-ART and U-ART tweeters, prioritize precision for recording, mixing, and mastering. This singular dedication to nearfield and midfield monitors has solidified ADAM's role in pro audio workflows.
ADAM Audio commands a premium position in the professional market, revered by sound engineers for sonic excellence, reliability, and benchmark-setting clarity. As an independent Berlin manufacturer, it caters to high-end studios and discerning home recordists, maintaining a global reputation built on over 25 years of innovation without corporate dilution.
