The AOS Studio 30 (S30) is a closed box MTM loudspeaker (Photo 1). The S30 is in many ways a bigger brother of the S24. I built this Studio 30 for use in a large room, so I changed the «bookshelf» format of the original AOS design to a full-size floor-standing loudspeaker. The S30 uses high-quality driver units made by ScanSpeak (Photo 2).
