Offered here is a rare Zenith Royal 55 speaker box complete with the radio. These speaker boxes were offered for a short time with the intent of giving the shirt pocket-sized Royal 50 a bigger table radio sound, and it worked, but it was not popular because everyone already had a table radio.
These speaker boxes proved to be a fragile item with thin plastic feet and a top-heavy design, especially with the radio inserted. Therefore, most of these have sustained substantial damage with very few have survived in collector condition. So here you can get the speaker box and the matching Royal 50 in fine playing condition.
