JBL 6012

Little is documented about the JBL 6012. What the record shows comes from a single dealer listing. The details below sound plausible for a JBL loudspeaker of its era, but nothing independent backs them up.

The 6012 is a loudspeaker rated at 125 watts power handling, with a frequency response of 45 Hz to 40 kHz, an 8-ohm impedance, and a sensitivity of 93 dB. It weighs 13 kg. A European audio resale site shows a current asking price of 340 EUR. Whether that reflects a completed sale is unclear.

Past those figures, almost nothing is recorded. No production years, original retail price, dimensions, driver complement, crossover details, or cabinet construction have turned up in the available documentation. Nothing confirms where the 6012 sits in JBL's broader lineup, and no period review has been found. Studio Sound (August 1978, p.50) covered power amplifiers in that era, but not this model.
