JBL 3125
Documentation on the JBL 3125 is thin. Here is what the record shows. It was a three-way, bass-reflex floorstanding loudspeaker with an 8-ohm impedance, a frequency range of 45-20,000 Hz, and a sensitivity rating of 88 dB/W/m. The crossover points were 800 Hz and 6,000 Hz. Each cabinet carried a 10″ woofer, a 3½″ midrange and a 3″ tweeter (hifi-wiki.com gives metric equivalents of 25 cm, 9 cm and 8 cm). Power handling was listed at 50 watts. The source doesn't say whether that's peak or continuous.
The 3125 measured 17½″ H × 14″ W × 8½″ D (approx. 45.1 cm × 35.6 cm × 21.6 cm) and weighed 25 lbs. (approx. 11.35 kg). The only finish documented is Oiled Walnut. No production years, original price or reception data have surfaced - no period reviews, no owner commentary, no maintenance information. One current listing on eBay priced a pair at $149.99 plus shipping. The listing's title ("vintage computer speakers") may not be an accurate description of this model. If you own a pair and know more about the era, sound or build quality, the archive would welcome the word.
HiFI-Stereo (May 1980, p.119) carried classified advertising for the period, but no review of the 3125 specifically has been located.
