This listing is for a single (1) JBL 353107-001 ultra high frequency tweeter, also known as a super tweeter. It was used in the following models: L810, L820, L830, L890, LC1, LC2, ES20, ES30, ES80, ES90 & ES100.

 Tweeter has been tested with music & a multi meter. It is in very good working condition. It has a few small marks on the diaphragm that I touched up with a tiny dot of silver paint (see picture #3). They were tiny dents, not holes.

 Impedance is 4 ohms & DCR = 3.6.
