Up for sale here is this new Polydax AMTIW74A8 3/4" dome tweeter.  This is an 8-ohm speaker and measures around 5.3 ohms on my multimeter.  This came from a closed repair shop.  It is tested and plays well and works great.  Please make sure this is the right driver for you. 

Please see my pictures for details.

US shipping and handling is $8, and international is $28.  If you have any questions, please ask. 

I have more speaker parts and other vintage electronics listed--feel free to take a look!
