<VV> speaker resistance 4 ohm, 8 ohm, 10 ohm??

[Roger Gault]

However, half the power is not "half" the volume.  You'd have to be 10db
down to sound "half" as loud to most folks.  3db is hard to hear if you're
not comparing side-by-side.  If you have one person talking and a second one
starts saying the same thing at the same time, that's 3db louder.
