This Atwater Kent Radio Speaker Horn was originally manufactured in Philadelphia in 1923. This Type M Atwater Kent Radio Speaker Horn was the only Atwater Kent that was built to swivel in its own base and was the first horn Atwater Kent ever made. Siren #153 is approximately 19” tall with a 14.5” bell and paired with a reclaimed floor joist found from a house restoration Swarthmore, PA. Finished with Betty’s Board Butter (beeswax & mineral oil). You may want to re-oil your base occasionally.

In the late 1920s, Atwater Kent was the largest producer of radios in the world. Between 1923-1929, The Atwater Kent Manufacturing Company factory, at the corner of Wissahickon and Abbottsford Avenues in northwest Philadelphia, built radios, receiving sets, radio horn speakers, and other components. The factory consisted of two plants, the South Plant and the North Plant, that together covered more than 34 acres. The two plants were connected by an enclosed pedestrian bridge in 1929; that bridge was destroyed when the Roosevelt Extension was built.
