JBL LX8 (1980)
The JBL LX8 is a floorstanding three-way loudspeaker introduced in 1980. It's a bass-reflex design with a 250mm (10") bass driver, a 125mm (5") midrange and a 25mm (1") dome tweeter. The crossover points are 800 Hz and 3,500 Hz. JBL rated it at 200 watts peak (100 watts RMS) into 8 ohms. The cabinet weighs 24kg. Frequency response is specified as 45 Hz to 20 kHz.
Documentation on the LX8 is thin. Sources agree on the driver complement and crossover points, but differ slightly on sensitivity - one lists 90 dB, another gives 89 dB / 2.83 V / 1 m. A 1979 issue of Audio (January 1979, p.137) noted that JBL's then-current flagship speaker, the Sovereign, could be driven either bi-amplified or through its internal crossover network.
Beyond that, almost nothing is recorded. No original price, no dimensions, no cabinet finish options, and no contemporary reviews have surfaced. If you own a pair and have documentation, the archive would welcome it.
