Trade Liquidation & Testing Scope

Sourced as corporate surplus from a commercial production facility. Both monitors have been power-on tested; the rear OLED setup displays, rotary encoder controls, and internal electronics respond cleanly without fault codes[cite: 26]. All driver units—including the delicate folded S-ART ribbon tweeters, composite midrange domes, and dual low-frequency woofers—are physically flawless with zero indentation, tearing, or surround damage[cite: 27, 29]. Supplied in their heavy-duty original factory boxes with tailored dense foam inserts[cite: 26, 28, 33].

Top panels show faint circular mug/coaster outline marks and light surface scuffs from gear being rested on top[cite: 30, 31].
Minor edge rubbing and paint abrasions along the bottom and side bevelled corners from standard console mounting/repositioning[cite: 30, 32, 35].
