Yamaha S12 is a compact two-way bass-reflex speaker system that delivers well-balanced, high-quality sound reproduction. Its 12 cm woofer and 2.5 cm tweeter provide powerful bass and delicate high-frequency sounds. It's suitable for use with various equipment, thanks to its standard 1/4" phone jack connectors and push-button type terminals. The speakers can be mounted horizontally or vertically on a wall or column, or suspended from the ceiling using an optional bracket.
