This 1922 Magnavox R3 14-inch horn speaker will eventually be on display at the New England Wireless and Steam Museum. Currently it awaits reconditioning of the companion radio that we have chosen to pair it with, the Grebe Synchrophase MU1. The R3 speaker was introduced in 1922 at a price of $45 and by 1923 it was reduced to $35. They sold very well!  →
