Brand New Genuine Cerwin Vega VE12, VE15, VE15F Tweeter. 113.6 ml or 4.5″ outside diameter. Metal dome. 6 ohms
This tweeter also makes a great replacement for the JBL CF120 & CF150 Tweeter.
You can use this tweeter to replace the DT1860 used in the LS10, LS12 and LS15, but you have to slightly enlarge the cabinet hole to fit the new tweeter.
