Utah Radio Products was a Salt Lake City-based company that supplied OEM components to Allied, Knight, and other radio brands. Orthovox-branded speakers are rare, likely produced by or in partnership with Utah. It is thought the Orthovox name emphasized orthophonic fidelity, a marketing term borrowed from Victor. It originally cost about $90 new in today's money.
This speaker is mid-30's and features a moving armature-driven cone. The speaker and cone are in very good condition, tested and works well. Speaker is about 6 1/2". Has a small crack in the cone at upper left near basket, paper however is in remarkable condition.
Polarity indicated by color. Center terminal is B+. Coil resistance is ~598 ohms, with 328 Ohm (pos) and 270 Ohm (neg) from center tap respectively. Fourth lug is chassis ground. May be able to use on other restoration projects as long as specifications are similar. For reference, the output tube that drove this was an RCA 19.
