MW Audio MM-0206: Infinity Quantum Series Copy 1.5″ Dome Midrange
Price is for 1 midrange. If you need more than 1, just adjust the quantity.
This is NOT a factory Infinity part as they are not available anymore. It is a great replacement midrange for the Infinity Quantum Line Source speakers. Below is a list of models that the mids will work well in.
The specs and parameters were copied from the original Infinity 902-0206 1.5″ dome midrange to ensure similar sound. Same impedance (8 ohms), face plate and screw holes. Some cabinets you do have to modify the hole just a hair for terminals that come out on the side of the magnet.
