Vintage ADS Tweeter for an L620 speaker p/n 206-0100 - work well

Description

Nice working  tweeter removed from an ADS L620 speaker with bad cabinets.  Part number  206-0100.  The tweeters work well and sound good.  Cosmetically they are overall in good condition with the one detractor being the bits of dust and particles stuck to the sticky dome material.  This appears to be common with these tweeters and does not affect the sound.  I have not tried to remove any of it as I did not want to damage the tweeter and read that the sticky coating is important for the tweeter damping.
Includes the four mounting screws.  This auction is for one tweeter.  I have two available.  If both are bought at the same time, I will provide a discount for shipping.  Thanks for looking.
