Description
Black and white 4 3/4″ x 12 1/2″ ad for their Labyrinth Radio. The ad headline generously calls it “The Greatest Tonal Advance in Radio History” and assures you that it can be yours for “As Low as $119.50”. The ad has a picture of a couple standing and staring in wonderment at the No. 340-V in an Early American Maple Corner Cabinet that sits in their house. The ad also has pictures of a No. 325-S which is in an Authentic Early American Design Maple Cabinet and a No. 345-F which has an Authentic Chippendale Design Mahogany Cabinet. The ad explains the theory to the outstanding sound these units were famous for. Addressing The Trouble of empty cabinet space allowing “boom” and “distortion” they developed The Theory of using a long tube to absorb the excess sound. Finding this answer impractical they developed The Theory made Practical by folding the long tube into a Labyrinth which could fit into the cabinet. The Patented Labyrinth is now the necessary baffle wrapped up and put in troublesome space in the cabinet. This ad is taller than my scanner bed so the outer edges of the ad will not be visible in the scanned view.
