The Privia PX-S1100 is the world's most compact 88-key digital piano with built-in speakers and hammer action. With a depth of just 232 mm, it fits into any living room, bedroom, or studio space. Despite its compact size, it fills the room with sound - the revamped speaker system optimally delivers excellent sound quality, ensuring stronger localization and presence. The Smart Scaled Hammer Action is designed to provide a playing experience akin to that of an acoustic keyboard instrument, despite its small size. Each of the 88 keys has its own weight and timing, enhancing authenticity.
