Jensen 10-TRI (c. 1959–1960)
Nearly everything documented about the Jensen 10-TRI comes from Jensen's own advertising. The ads ran in American hi-fi magazines from late 1959 through mid-1960. They identify it as the TR-10 Tri-ette, a three-way bookshelf speaker system built on the air-suspension principle. It used Jensen's FLEXAIR high-compliance moving system and BASS-SUPERFLEX enclosure acoustics. The campaign pushed it for both stereo and mono listening, invited comparison with any other bookshelf speaker, and claimed the model's popularity was growing rapidly.
The only hard figures in the record come from Jensen's price list, shown in its High Fidelity advertisement (February 1960, p.3). The TR-10 Tri-ette was $119.50 and the unfinished TR-10U was $139.50. An earlier appearance in Audio (October 1959, p.31) confirms the model was in distribution by autumn 1959. No independent test report of the 10-TRI from the period has surfaced in the surviving record. Beyond the advertising claims and prices, little is known.
