The Klipsch kg4 is a two-way floor-standing speaker system featuring unusually high efficiency (for a home speaker) combined with an extended, smooth frequency response. Its handsomely finished oak-veneer enclosure is 24-1/4 inches high, 15-3/4 inches wide, and 10-3/4 inches deep, and the system weighs 45 pounds. The dark brown, wood-framed cloth grille is retained by strong plastic fasteners and requires considerable effort for removal.
The front panel of the kg4 contains two white plastic-cone woofers, one above the other, with a nominal diameter of 8 inches. At the top of the panel is a horn-loaded tweeter—a device unusual in home speakers—with mouth dimensions of 8-1/2 x 3 inches. The crossover frequency is 1,800 Hz. On the rear panel of the enclosure is a 12-inch passive cone radiator that extends the low-frequency response limits of the smaller bass drivers. The binding-post terminals, recessed into the rear of the cabinet, accept banana plugs, including dual plugs on 3/4-inch centers, as well as wires. There are no external controls or adjustments
The speakers are 9/10 - Incredible condition
