Technics SB-F3
Little is documented about the Technics SB-F3. The sources examined turned up no original specifications, price or production dates. The model never appears in a complete period listing either.
What the record does show is that the name puts the SB-F3 in Technics' SB-F speaker series. A 1983 HI-Fi-Stereo-Buyers directory (p.152) lists two mounting accessories for the related SB-F1 and SB-F2 - an SH-S2 angle mount at $40 and an SH-S3 suspension chain/bracket at $30. That suggests these were speakers meant for flexible placement, on stands or walls. The same directory pages also carry a Technics speaker entry with a truncated model name. It describes a 10-inch cone woofer, 4-inch cone midrange, tapered-flare radial horn tweeter, 100 W music / 65 W continuous power handling, 8-ohm impedance, tweeter level control, and resettable thermal protection (HI-Fi-Stereo-Buyers, 1981, p.199). That entry cannot be confirmed as the SB-F3, but it brackets the kind of technology the series used.
Beyond that, the record goes quiet. If you have an SB-F3, a photo of it and its rear label would be a real help to the archive.
