Altec Lansing 89
Not much information on the Altec 89 has survived. Here is what the record shows. It was a three-way bookshelf loudspeaker system with a 12″ woofer, a 1″ horn driver and a 1″ dome tweeter, all in a bass-reflex enclosure. The driver complement and crossover network were designated the 892A assembly. An optional 892 enclosure and grille were also sold separately.
The specs describe a capable, high-sensitivity design. It is rated at 94 dB at one watt, one meter, and was intended for amplifiers delivering 10 to 175 watts RMS. Crossover points were set at 800 Hz and 4500 Hz, and the system was rated 125 watts program power. Each cabinet measured 26″ H × 16¼″ W × 12¾″ D and weighed 55 pounds.
