The JBL LS40 is a three-way monitor speaker designed to deliver high-quality sound through a well-engineered driver configuration. It features a unique combination of a supertweeter, a high-frequency tweeter, and a low-frequency woofer, which together provide a broad frequency response and tightly focused soundstage. The supertweeter is a 0.75-inch polyimide ring radiator, while the high-frequency driver is a 2-inch pure titanium dome housed within a Bi-Radial horn. The woofer, made from pure pulp fiber, emphasizes JBL's commitment to using quality materials for sound reproduction. A distinctive feature of the LS40 is its medium-density-fiberboard enclosure, designed with curved sides to eliminate standing waves and enhance sound clarity. The speakers are available in beautiful high-gloss ebony or mahogany finishes, which improve their aesthetic appeal. Bi-wire capability is provided via gold-nut binding posts for flexible connectivity.
