Adam Audio S2A – in excellent condition – in perfect working order

For sale: a pair of Adam Audio S2A – legendary studio monitors originally priced at 85,000 CZK. They are highly regarded for their detail in the midrange and treble. They feature the original ART ribbon tweeter, which is considered the best of all ART tweeter models (ART-X and ART-S). This is a fully analogue monitor, without DSP, which is still highly regarded today for its natural sound and frequency response. You can listen to them at my studio; given their size and weight, I prefer collection in person.

The ADAM Audio S2A is a professional two-way active studio monitor that utilises ribbon tweeter technology (ART) for detailed high-frequency reproduction and a HexaCone woofer for precise bass.
