JBL L150 (Late 1970s – Early 1980s)
The JBL L150 was part of the company's consumer speaker lineup during the 1970s and 1980s. It sat alongside the L65 Jubal, L112, and the flagship L300 Summit. It was a full-range home loudspeaker that drew on JBL's studio monitor heritage. Surviving documentation on its exact driver complement, cabinet dimensions, and price is thin.
The period press is clear on the strengths. High Fidelity (August 1979, p.47) led with the headline "JBL's New L150 - Bottom Puts It On Top," which tells you where the reviewer's attention went: low-frequency extension. A follow-up review in the same magazine (October 1980, p.19) called the bass "reproduced with depth and power that few speakers can equal." It was tight, free of boom, and capable of levels approaching live performance without distortion. HiFI/Stereo (February 1980, p.48) measured tone-burst response at 100, 1,000, and 10,000 Hz and found distortion unusually low. It was 0.21 percent at 70 Hz, rising smoothly to 0.45 percent at 50 Hz, and just 2 percent at 25 Hz. In listening comparisons with other comparably priced speakers, the L150 showed no coloration to program material.
The published reviews note a 5-inch midrange transducer and a dome radiator tweeter for wide dispersion. The full driver configuration, crossover points, and enclosure specs are not recorded in the available archive.
