How can you tell that the power will be low into 4 ohms? I don't know much
about this subject, but I would have thought that if you get 90W into 8
ohms, 125W into 6 ohms, then reducing the impedence further to 4 ohms would
have meant the power would go up again- not fall. How does this work?


If you look at the two sets of figures, even for the modest power rise
into 6 ohms, they had to accept a hugely increased distortion figure.
That effectively means that the amplifier has already gone past its
comfort zone at 6 ohms so 4 would be asking too much.
