Usher Audio Technology speakers and electronics are built for the experienced listener who won't compromise on sound quality even at moderate prices. The CP-6391 is the heavy hitter of the 6 Series, a 3-way design with a large 10-inch woofer for solid 24Hz extension, a 7-inch mid-bass driver, and a 1-inch silk-dome tweeter mounted on top to avoid diffraction effects resulting in a more natural sound and better imaging. The speaker delivers an effortless, powerful, transparent and engaging sound from beautifully crafted and lustrously finished cabinets made with leading-edge components at very affordable real-world prices. They're as accomplished with two channels as they are in surround applications, and work best with solid-state amplifiers. The CP-6391 is available in a number of richly-finished colors including Ferrari Red, Gloss Yellow, and Piano finishes in White, Black, or Silver. No compromise performance means Joseph D'Appolito-approved bi-wire/bi-amp crossovers, removable solid brass jumpers, and massive cast-iron bases plus four oversize solid-brass cones to couple the speaker to the floor.
