USED - 1989 Allison Acoustics LC110 Wood Bookshelf Speakers (Set of 2)

The Allison LC110 is the smallest of the three speakers that make up the company's "Room-Matched" series. These are conventionally constructed, compact, two-way systems that are designed to achieve a proper balance of bass-to-treble energy when they are placed close to one room surface. According to Allison, the best results are obtained with the woofer end of the cabinet resting on the floor, a few feet from the nearest wall and farther away from other walls. The speakers can also be placed on stands, tables, or bookshelves.

The LC110 features the same convex-diaphragm tweeter used in every other Allison speaker. This driver-noted for its wide, smooth frequency response and excellent dispersion-is designed to simulate the motion of a pulsating hemisphere, and it is cooled and damped by ferrofluid. The tweeter crosses over at 2,000 Hz to an 8-inch acoustic-suspension woofer operating in an enclosed volume of 930 cubic inches. The quarter-section crossover network uses an air-core inductor and a computer-grade nonpolar capacitor.

The system's impedance is rated at 6 ohms nominal and 4 ohms minimum. Other specifications include a sensitivity of 90 dB sound-pres-sure level (SPL) at 1 meter with an input of 2.83 volts, a low-frequency resonance of 59 Hz (with the bass output down 3 dB at 46.5 Hz and 6 dB at 39 Hz), and a recommended amplifier driving power of between 15 and 150 watts.

The wooden cabinet of the Allison LC 110 measures 18 inches high, 11-1/2 inches wide, and 7-1/2 inches deep, and each speaker weighs 16-1/2 pounds. The cabinet is finished in walnut-grain vinyl. The removable sculptured grille, made of black perforated plastic, snaps into a groove around the speakerboard. The spring-loaded connectors recessed into the rear of the cabinet accept the stripped ends of speaker wires or dual banana plugs.
