The sound output has been confirmed, but it is currently sold at a low price. A rare Yamaha 1 inch driver horn. I don't know the detailed specs, but when I connected to the 800Hz crossover network and made a sound, the piano and stringed instruments sounded powerfully with no fog. Comes in a wooden cabinet. How about a high frequency system for self-made people (Sasaki Shota)
