Stromberg-Carlson RF-460 (c. 1954–1958)

The Stromberg-Carlson RF-460 was an 8-inch loudspeaker in the company's Custom Four Hundred component line. Formal documentation is thin. No original manual or factory spec sheet appears in the archive, but the model shows up in period advertising and component listings from 1954 to 1958.

The published specs drifted a bit over that span, which suggests a long catalog life with running changes. Early ads in High Fidelity (September 1954, p.101) and Audio (August 1954, p.37) listed 50-13,000 cps response, 12-watt power handling, and 8-ohm impedance. A 1956 High Fidelity ad (September 1956, p.23) listed the RF-460 at $20 and described the cone as curvilinear and molded, with a stiff center meant to improve treble and widen sound coverage. A later High Fidelity component listing (March 1958, p.16) raised the ratings to 18 watts and 45-14,000 cps. It was sold alongside larger siblings including the RF-473 12-inch and the RF-475 15-inch coaxial.
