No Speakers Needed

With Yamaha's TransAcousticâ„¢ technology there's no need to connect external loudspeakers. At its most basic level, TransAcoustic technology turns the piano into a 'loudspeaker' and the soundboard is working as the membrane for that loudspeaker. There's no need to purchase extra speakers and cables. The piano is ready for you to play as soon as it's delivered into your home.
