About 34 in tall, 15 in wide, 3 way-12,5,3, 250 watts ea, champagne gold faceplate along bottom front with: "marantz" and "sound overload protection", graph image, orange power light,gold tweeter control button. Brown cloth grills, dark wood veneer is gorgeous.Gold overlay rings over speakers.I guess them to be about 1980 but could use some help with the model number.
