Up for sale here is this used or possibly unused Peerless 811830 dome tweeter.  This is an 8-ohm speaker and measures around 5.6 ohms on my multimeter.  This came from a closed repair shop.  It is tested and plays well and works great.  The dome might have a very slight wrinkle--I don't think so, but it's hard to tell.  Please make sure this is the right driver for you. 

Please see my pictures for details.

US shipping and handling is $10, 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!
