1980's Realistic 2 inch PIEZO TWEETER speakers, Cat. No. 40-1383

For Sale-   Listing is for ONE PAIR of tested and working classic tweeters. Three pairs are available.

Good sound quality, no issues.

I purchased these new back in the 1980's.  They are supposed to be burnout proof and do not require a crossover network- just hook them up in parallel with your other drivers.  If I remember correctly piezo tweeters read very high resistance on a meter but they work fine. 

Email your zip code for ship cost - should be between $3.99 and $5.99 if you are in the continental US (listed August 2013).
