THIS IS A YAMAHA HS50M SPEAKER MONITOR in excellent condition. THE SPEAKER WORKS BUT THE AMPLIFIER NEEDS REPAIR OR FOR PARTS. I DO NOT HAVE THE EQUIPMENT FOR TESTING THESE SPEAKERS BECAUSE I DO NOT HAVE THE APPROPRIATE CABLES AND AMPLIFIER. I TESTED ONLY THE SPEAKER DIRECTLY TO RECEIVER. FOR MORE DETAILS, LOOK AT THE PICTURES AND SHORT VIDEO. I AM SELLING FOR PARTS OR REPAIR. AND AT A LOW COST.
