SPEC SHEET

This 4 inch Aluminum Alloy Tweeter, 4 ohm, with Front-Mounting panel. It has good process ability and
high yield for mass production. Because of this special raw material structure and unique processing
technology, from magnesium lithium metal foil, the attributes of Magnesium Lithium offer high strength,
good rigidity, good heat resistance, low density and so on.
