Vintage 1920s Jensen Loudspeaker Heavy Steel Case w Chrome Trim & Feet Speaker. Vintage 1940s National NC-2 TS Loudspeaker. Here we have a vintage 1940s NC-2 TS speaker. It features chrome trim & feet. The speaker is 10 in diameter. The cabinet measures 15 3/4″ wide x 11 1/4″ tall x 10 deep. I tested it with a 9 volt battery and it clicks loud and clear, indicating that it works. The cone is in excellent shape with no issues. We believe this is the companion speaker to the National model NC-240 shortwave radio. Please scroll down to view all the pictures and feel free to ask questions.
