Steakster,
You've got good reason to be confused - I don't understand
part of it either.
First, it's the electrostatic panel that's the problematic
actor here. Secondly, the impedance of the panel doesn't
drop to 0.5 ohms at loud volume - at high frequency; yes -
but not high volume.
Let's assume that the woofer is a 6 ohm woofer. The bi-wire
model - with two sets of binding posts - can probably be
used with a single wire pair by putting in a jumper. That
puts the woofer in parallel with the panel. So when the
panel impedance drops - the fact that you have a 6 ohm
woofer in parallel with the low impedance doesn't make any
difference - your amp still sees a low impedance.
When speaker manufactures supply only a single pair of
binding posts - the jumper is on the inside - the two
drivers are still in parallel and the above applies.
The only thing I can think of is that the earlier model
puts the woofer in series with the panel. That way the
impedance of the system will not drop below that of the
woofer.
That's not the usual way - but perhaps that's what Final
did in order to "tame" the low impedance of the panel -
and give a more benign impedance for the system.
