The Radiola UZ-1325 loudspeaker was manufactured by the Radio Corporation of American and utilized a horn manufactured by the Miller Rubber Company (as did all of the upright horns manufactured by RCA). The UZ-1325 was introduced for the 1924 Christmas season and was the last horn marketed by RCA; by the end of 1926, RCA stopped selling horn speakers and moved entirely to cone type speakers.

This rubber radio speaker horn stands approximately 21” with a 12” bell (the whole piece is 24” tall x 12” wide x 8.75” deep) with its original metal label. The base is made from salvaged black walnut and finished with Betty’s Board Butter (Beeswax & mineral oil.) You may wish to re-oil your base occasionally. If your phone has stereo options you may want to play around with mono and stereo settings to see which you prefer.
