A high-efficiency speaker system from Altec Lansing, with MantaRay horns and an 8-ohm impedance.
Overview
The Altec Model 14 is a speaker system Altec Lansing built between 1979 and 1984. It was marketed as one of the most efficient speakers the company ever produced. It uses the MantaRay MR931 horn and the 902-8B high-frequency driver, which has Altec's Tangerine phase plug for extended high-frequency response. Nominal impedance is 8 ohms and the crossover frequency is 1.2 kHz. Richard Christianson developed a redesigned crossover in the mid-2000s for improved performance.
