MW Audio MT-4003: 1 inch Polyester Dome Tweeter

Good overall sounding tweeter for any home audio application. 8 ohm: ***Great replacement for the high output polycell tweeter used in many Infinity Studio Monitor speakers. Faceplate and screw holes line up perfect, but you will have to file/route the cabinet for the terminals. The terminals are on opposite sides of the magnet instead being next to each other. On some cabinets, you may also need to file/route the opening about 1/16″ for the magnet. See pictures.
