I?ve come into a pair of MR902-16HF Horn/Drivers. The spec sheet claims it to be a UHF system with a ?low mass aluminum diaphragm? and ?new ferrite magnetic structure? with a recommended crossover frequency of 5000 Hz or higher. The spec sheet also states that the diaphragm is a 34852 (present and working perfectly) which is the standard 16ohm diaphragm used in the 802/902-16ohm drivers. The driver itself appears to be a 902 driver minus the rubber magnet cover. In addition to a 6uf protection capacitor the diaphragm has a loading cap which I understood to limit high frequency output which doesn?t seem to make sense in a system designed to be an UHF system.

Is this all Altec marketing hype and the driver is really a 902 without cosmetics like the 416-16Z is a 416-16A without the cosmetic magnet cover and does the loading cap help or hinder high frequency output? Can you get the same or better high frequency output with a 902A driver (no loading cap) paired with the MR902 horn.
