Altec Lansing MR902-16HF
A high-frequency horn tweeter designed for professional and high-fidelity audio systems, featuring a manta ray Lehorn for controlled dispersion.
Overview
The Altec Lansing MR902-16HF is a horn-type tweeter manufactured by Altec Lansing, known for its use in precision audio applications. It features a 45mm voice coil and is engineered to operate efficiently with a proper crossover frequency of 5 kHz or higher. With a frequency response ranging from 2.5 kHz to 20 kHz, it delivers strong high-frequency output with an efficiency of 103dB per watt at one meter (new JIS standard). Built for reliability, it handles up to 15 watts of input power and presents a nominal 16-ohm impedance.

Design
The MR902-16HF uses a manta ray Lehorn, a horn design that prevents the directional characteristics from becoming beam-like as frequencies increase. It incorporates the newly developed driver 902-16A, which combines the manta ray Lehorn with a Tangerine phase plug and is integrated with a mounting bracket for secure installation.
