JBL LT1

Documentation on the JBL LT1 is thin — the record that survives comes down to a single personal vintage-audio site, with no production years, original price, or period advertising to pin it down. What the record does show is a three-way floor-standing loudspeaker with a 200 mm woofer, a 100 mm midrange, and a 25 mm tweeter, crossed over at 1,2 kHz and 4,5 kHz. Sensitivity is listed at 90 dB, nominal impedance at 8 ohms, frequency response at 45 Hz–22 kHz, and power handling at 100 W.

Almost nothing else is documented. There are no cabinet details, no dimensions or weight, no product-family context within JBL's lineup, and no owner commentary. A period review did appear in Studio Sound (October 1984, p.106), which covered the LT-1, but the surviving scan is fragmentary and yields no usable measurements or verdicts.
