I sell my Adam aufio A7X studio speaker because i can not find to buy a second single speaker so maybe is easier to sell it and buy a pair. It is in perfect like a new condition and comes with the original box and powet cable, can be tested in Friedrichshain
ADAM’s a7X has long been a respected nearfield monitor, and at €300 this looks like a strong deal against the recent local market. With a median of €804 and a 25th percentile of €552, the asking price sits well below the typical used range and is firmly bargain territory.
That makes it especially appealing if you want fast, revealing top-end detail and tight imaging for mixing or critical listening. Excellent condition is a real plus here, and at this price the main check is straightforward: confirm both drivers are clean, the amps are quiet, and all inputs/functions work properly. If it passes that, this is a very attractive buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
