Jensen TR-10 (c. 1959–1960)
The Jensen TR-10 "Tri-ette" was a three-way bookshelf loudspeaker system sold around 1959-1960. Little is documented about it beyond Jensen's own advertising. No independent test report from the period has surfaced in the usual archives, so the record rests almost entirely on the company's full-page magazine campaign.
Jensen's ads ran in both consumer and trade publications, and they told the same story every time. The TR-10 used the air-suspension principle, with Jensen's "Flexair" high-compliance moving system and "Bass-Superflex" enclosure acoustics. It was pitched at both stereo and mono listening. The copy pushed buyers to compare the Tri-ette with any other bookshelf speaker, the target being a compact box that could handle both channels. A High Fidelity ad (February 1960, p.3) listed the TR-10 at $119.50 and a TR-10U "Unfinished" version at $139.50. An Audio ad (October 1959, p.31) made the same Flexair/Bass-Superflex claims.
What the ads establish:
- 3-way bookshelf speaker system
- Air-suspension loading; "Flexair" high-compliance driver system; "Bass-Superflex" enclosure
- Marketed for stereo and mono use
- TR-10: $119.50; TR-10U (unfinished): $139.50 (per February 1960 ad)
Driver complement, cabinet dimensions, frequency response, and exact production run are not documented in the sources available. If original paperwork or a period review of the Tri-ette turns up, it would genuinely fill a gap in the record.
