About the L7

The JBL L7 is a four-way, tower-style vented speaker system introduced in the early 1990s as the top model of JBL's L Series. It features a 12-inch side-firing woofer, an 8-inch mid-bass driver, a 5-inch midrange driver, and a 1-inch pure titanium dome tweeter. The cabinet is constructed from high-density and medium-density fiberboards with extensive internal bracing and lock miter corners for rigidity and reduced vibration. The speaker is finished in black satin lacquer fronts with black lacquer over real oak veneer sides and tops. It has a narrow, tall enclosure with a slanted front baffle for correct time alignment and excellent imaging. The L7 is rated at 91 dB efficiency and can handle up to 450 watts per channel, producing a large, room-filling soundstage with near live performance sound pressure levels. It supports bi-wiring and bi-amping with two sets of heavy 5-way binding posts. The drivers use JBL's Symmetrical Field Geometry magnetic design for low distortion and high power handling. The tweeter dome and surround are made from pure titanium for high stiffness and peak power capability. The speaker includes a 4-inch diameter, 8-inch long rear-mounted plastic port and a supplied plastic base for lateral stability. The L7 is known for its powerful, articulate bass and detailed midrange and treble, making it a favorite among audiophiles and serious listeners.
