JAMO 20602 2-3/4" Square Frame Sealed Back Mid/Tweeter
great speaker for replacing blown tweeters or mid range/tweeters in home systems.  it's labeled Sony 8 ohm.  Not sure why it's called Jamo.  Used this to replace a  worn tweeter in a car hatchback speaker box.  I ultimately abandoned the mids and  highs and just dedicated the whole box for sub woofing.  Glad I got these in the  event I do blow a tweeter or two.  The price was right for experimenting.
