Final 0.3 ELS bass unit and x/over


2005-08-06 7:03 am
I have a pair of final 0.3 ELS which I love the sound of but I have a problem which i need advice on.
yesterday one of my bass units stopped working and when I tested the diaphragm it was locked solid and would not move. Also I find that the Els panel for that speaker works without being powered by the mains, which I find very interesting since the other panel needs mains power to fire up. I know nothing about the intrinsics of ELS and can only assume that maybe the x/over is faulty as well.
Does anyone know of a good replacement pair of bass drivers for these speakers and why one of my ELS panels doesn't require mains power?
Any help would be appreciated.
