Vintage Machine Age Motorola 8 Round Speaker Chrome Metal Case Works – Art Deco. This is a vintage 1930s 8 Motorola speaker. The cylindrical metal case features a chrome front and a nice red and chrome Motorola emblem. It sits on its two original cylindrical feet. I have tested it with a 9-volt battery and got a good loud response, also just tested with our big Hallicrafters S-36 and it works, sounding great for its size. It measures 8″ wide x 8 1/4″ tall and is 4 deep. Please scroll down to view all the pictures and feel free to ask questions.
