Hi
What I have learned from this forum by Giskard and others is that the voice coil to the LE15A was the same in the 8 ohms and in the 16 ohms versions. JBL used the same spec. voice coil regardless of the two models.
Could this allso be the case with other JBL transducers?
As an exampe, I have LE8Ts which gave the following results when measured:
1. DCR: 12,9 ohm Z: 14,3 ohm JBL label marked as 8 ohms
2. DCR: 3,56 ohms z: 4,7 ohms JBL label marked as 8 ohms (LE8T-H cone)
3. DCR 5,22 ohms z: 7,3 ohms JBL label marked as 8 ohms
(z was measured at 1kHz)
No 2 was found to be the oldest of the speakers measured
When measured two new LE8T-Hs cone kits I found it to be 6,1 and 6,3 ohms (DCR) respectively
A litle bit confusing eh ??!!
Any comments on this subject.......?
