JBL 3120

Documentation on the JBL 3120 is thin. It shows up in period classified and dealer listings - Recording Engineer (April 1991, p.77) and HiFI-Stereo (September 1992, p.98) both list it as used equipment - but JBL never seems to have left much of a paper trail. What the record does establish: it is a 3-way floorstanding loudspeaker, and a powered subwoofer variant, the P3120, was also marketed around the same time.

The HiFi Engine listing gives the known specs. They are modest, and consistent with JBL's late-80s/early-90s consumer line:

System type: 3-way floorstanding speaker
Frequency response: 55 Hz – 20 kHz (±3 dB)
Sensitivity: 90 dB (1W/1m)

Beyond that, almost nothing is recorded. No crossover points, driver complement, or power handling figures have turned up in any documentation we've been able to locate. If you own a pair and have the original manual or spec sheet, we'd be glad to hear from you.
