"The production L250 was introduced in 1982. The B460 subwoofer was developed at the same time, and was marketed with the L250 as the ultimate accessory. Given that the L250, was flat to 30hz, it could function quite capably without the subwoofer. Nonetheless, the addition of this sub resulted in the first JBL system that had frequency extension beyond the limits of human hearing at both extremes. The industrial design was performed by Doug Warner and was an elegant expression of the speaker's function. Doug was responsible for recommending the trapezoidal enclosure shape that accomplished the engineering function of the original pyramid design, but resulted in a more satisfying, understated appearance.
The driver compliment in the L250 consisted of the LE14H-1 bass driver, the 8" 108H midbass, the LE5-11 midrange, and 044-1 aluminum coated dome tweeter. In 1984, the tweeter was replaced with the titanium diaphragm 044Ti and the midrange was replaced with the 104H. This midrange driver was the first JBL transducer to use a polypropylene cone. The revised system was named the L250Ti and the driver compliment has remained pretty much constant thereafter. There were a number of refinements in the network designs through various re-issues such as the Limited Edition, Classic and Jubilee. The latest Jubilee incorporates the "Charge-Coupled Linear Definition Dividing Network" that was pioneered in the K2-S5500. "
